                               ($0.001 Par Value)

     Pursuant to Rule 429 of the Securities Act of 1933, as amended (the
"Securities Act"), this prospectus incorporates Aureal Semiconductor Inc.'s
earlier Registration Statement (the "Prior Registration Statement") on Form
S-2/A-2 (No. 333-39939) and updates certain information contained therein. The
Prior Registration Statement relates to, among other things, the Shares (as
defined below) issuable upon conversion of the Series A Shares (as defined
below), the Shares issuable upon exercise of the Series A Warrants (as defined
below) and the Common Shares (as defined below).

     Of the aggregate 32,110,000 shares, par value $0.001 (the "Shares"), of
Common Stock of Aureal Semiconductor Inc., a Delaware corporation ("Aureal" or
the "Company"), offered by this Prospectus, 70,000 Shares are issued and
outstanding (the "Common Shares"), 3,750,000 Shares are issuable upon conversion
of issued shares of Series A Preferred Stock of the Company (the "Series A
Shares"), 23,200,000 Shares are issuable upon conversion of issued shares of
Series B Preferred Stock of the Company (the "Series B Shares"), 3,600,000
Shares are issuable upon conversion of issued shares of Series C Preferred Stock
of the Company (the "Series C Shares"), 1,350,000 Shares are issuable upon
exercise of issued warrants to purchase Common Stock (the "Credit Warrants") and
140,000 Shares are issuable upon exercise of issued warrants to purchase Common
Stock (the "Series A Warrants"). With respect to the Common Shares, the Series A
Shares, the Series B Shares, the Series C Shares, the Credit Warrants and the
Series A Warrants issued by the Company, the Company relied upon the exemptions
provided by Section 4(2) of the Securities Act of 1933, as amended (the
"Securities Act"), and Regulation D promulgated thereunder as transactions by an
issuer, none of which involved a public offering (the "Exemption"). With respect
to the Shares issuable upon exercise of the Credit Warrants and the Series A
Warrants and the Shares issuable upon conversion of the Series A Shares, the
Series B Shares and the Series C Shares, the Company will rely upon the
Exemption. None of the Shares being registered hereby is being offered to the
public by the Company. Accordingly, the Company will not receive any of the
proceeds from the resale of such securities.

     The Common Shares, the Series A Shares and the Series A Warrants were
issued in connection with a privately placed equity financing to institutional
investors (the "Series A Selling Stockholders") pursuant to a series of
subscription agreements (the "Series A Financing Agreements"). The Series A
Shares are convertible into shares of the Company's Common Stock, calculated
pursuant to a formula based on the lower of (i) $2.50 (the "Fixed Conversion
Price") or (ii) a defined percentage (not less than 80%) of the lowest average
closing bid price of the Company's Common Stock for any five (5) trading days
during the thirty (30) trading days immediately preceding the date of conversion
(the "Variable Conversion Price"), all as set forth in the Company's Certificate
of Designation for the Series A Shares (the "Series A Certificate of
Designation"). Conversion of the Series A Shares can commence any time after
July 11, 1998. Variable Conversion Price conversions can be completed at the
rate of 15% of the originally issued Series A Shares per month. Hence, 100% of
the Series A Shares are available for Variable Conversion Price conversion as of
January 1999. No such limitations apply to Fixed Conversion Price conversions.
The Series A Certificate of Designation also gives the Company the right to
redeem some or all of the Series A Shares at a per share price equal to a
percentage of the purchase price of the Series A Shares being called for
redemption, ranging from 115% to 130%, depending upon the date of the
redemption. The Common Shares and the Series A Warrants were issued as
compensation to certain persons as part of the Series A Preferred Stock
financing. The

                                       4
<PAGE>   5

Series A Warrants were issued to such persons (the "Series A Warrant Selling
Stockholders") in February 1998 and have an exercise price of $2.50.

     The Company issued Series B Shares with a conversion value of $39.375
million in exchange for the cancellation of $31.5 million of indebtedness under
the Company's prior line of credit held by entities controlled by TCW Special
Credits and DDJ Capital Management, LLC (the "Series B Selling Stockholders"),
holders of approximately 44% and 17% of the Company's outstanding Common Stock,
respectively. The Series B Shares are convertible into shares of the Company's
Common Stock based on a conversion rate of $2.50, as set forth in the Company's
Certificate of Designation for Series B Shares (the "Series B Certificate of
Designation"). The Series B Certificate of Designation provides for, among other
things, (i) the payment of dividends, in cash or Series B Shares, at the rate of
eight percent (8%) per annum, (ii) the right of the Series B Selling
Stockholders to vote the equivalent number of shares of the Company's Common
Stock as would be held upon conversion of the Series B Shares and (iii) the
redemption of the Series B Shares at face value (plus accrued but unpaid
dividends) at any time at the option of the Company.

     The Company issued the Series C Shares in connection with a privately
placed equity financing to institutional investors (the "Series C Selling
Stockholders") pursuant to a series of subscription agreements (the "Series C
Financing Agreements"). The Series C Shares are convertible into shares of the
Company's Common Stock, calculated pursuant to a formula based on the lower of
(i) $2.50 (the "Fixed Conversion Price") or (ii) a defined percentage (not less
than 80%) of the lowest average closing bid price of the Company's Common Stock
for any five consecutive trading days during the thirty (30) trading days
immediately preceding the date of conversion (the "Variable Conversion Price"),
all as set forth in the Company's Certificate of Designation for the Series C
Shares (the "Series C Certificate of Designation"). Conversion of the Series C
Shares may commence at any time after October 26, 1998. Variable Conversion
Price conversions can be completed at the rate of 15% of the originally issued
Series C Shares per month. Hence, 100% of the Series C Shares are available for
Variable Conversion Price conversion as of April 1999. No such limitations apply
to Fixed Conversion Price conversions. The Series C Certificate of Designation
also gives the Company the right to redeem some or all of the Series C Shares at
a per share price equal to a percentage of the purchase price of the Series C
Shares being called for redemption, ranging from 115% to 130%, depending upon
the date of the redemption.

     The Credit Warrants were issued to Goldman Sachs & Co. and Transamerica
Business Credit Corporation (the "Credit Warrant Selling Stockholders" and
together with holders of the Common Shares, the Series A Selling Stockholders,
the Series B Selling Stockholders, the Series C Selling Stockholders and the
Series A Warrant Selling Stockholders, the "Selling Stockholders") in connection
with a $40 million line of credit entered into with the Technology Finance
Division of Transamerica Business Credit Corporation and Goldman Sachs Credit
Partners LP . The Credit Warrants are exercisable at any time during their five
year term and have an exercise price of $2.156 per Share.

     The Company will bear all out-of-pocket expenses incurred in connection
with the registration of the Shares, including, without limitation, all
registration and filing fees imposed by the Securities and Exchange Commission
(the "Commission"), the National Association of Securities Dealers, Inc. (the
"NASD") and blue sky laws, printing expenses, transfer agents' and registrars'
fees, and the reasonable fees and disbursements of the Company's outside counsel
and independent accountants, but excluding transfer or other taxes and other
costs and expenses incident to the issuances of the Shares.

     The Company's Common Stock is quoted on the Over-the-Counter Electronic
Bulletin Board (the "OTC Bulletin Board") under the symbol "AURL". On August 19,
1998, the average of the closing bid and asking price of the Company's Common
Stock was $1.234. The 32,110,000 Shares being offered hereby represent
approximately 47% of the Company's total outstanding securities, recognizing
that 32,040,000 Shares being registered herein are subject to issuance by the
Company pursuant to conversion of the Series A Shares, the Series B Shares and
the Series C Shares and exercise of the Credit Warrants and the Series A
Warrants but are not currently outstanding. Registering such a large percentage
of the Company's total outstanding securities may have an adverse effect on the
market price for the Company's Common Stock.

                                   THE COMPANY

     Aureal Semiconductor Inc. is a producer of audio semiconductor products and
advanced audio technologies for the PC and consumer electronics markets. The
Company contracts with independent silicon foundries for production of its
semiconductor products, and thus is a "fabless" semiconductor company. The
foundry that manufactures the majority of the Company's semiconductor products
is one of the three largest foundries in the world that manufacture products
exclusively for third parties. The Company's objective is to be a leading
provider of advanced digital audio solutions for the PC and consumer electronics
markets. In its pursuit of this objective, the Company has had several
significant accomplishments over the past year.

     Most recently, in August 1998, the Company introduced the Vortex 2 AU8830
audio processor (the "Vortex 2"), the newest generation solution for advanced
audio features on personal computers. The Vortex 2 is the only processor which
provides dedicated processing power for A3D 2.0 technology. It is a significant
upgrade to the original Vortex AU8820 Digital Audio Processor (the "Original
Vortex") that the Company is currently shipping. The Company commenced sales of
the Vortex 2 during the third quarter of 1998.

                                       7

     In July 1998, the Company announced that it had entered into a strategic
alliance with Diamond Multimedia Systems, Inc., a leader in the interactive
multimedia market, to co-develop and market PC audio solutions for the PC
consumer and game markets.

     In June 1998, the Company announced that Compaq Computer Corporation, the
world's leading personal computer company, would begin featuring Aureal's A3D
Interactive 3D audio technology on its new line of Presario desktop computers.

     In April 1998, the Company introduced A3D 2.0, a significant enhancement to
the existing version of A3D that was originally introduced in September 1996.
The new A3D 2.0 includes Aureal Wavetracing Technology (which enables real-time
acoustic reflections, reverb and occlusion rendering features), more 3D sources,
a higher sample rate and larger Head-Related Transfer Function (HRTF) filters.
Together, all of these feature enhancements provide for improved
three-dimensional rendering of audio for interactive applications.

     In February and March 1998, Aureal announced several major design wins for
the Original Vortex, including: Dell Computer Corporation, the world's leading
direct computer systems company; Turtle Beach Systems, a leading U.S. provider
of premier audio products for the PC; TerraTec Electronic GmbH, a leading
European provider of sound card products; and Aztech Systems Ltd., a leading
sound card retail and OEM company. By these design wins, the foregoing
manufacturers have agreed to incorporate the Original Vortex in their products
or in their component parts for their products. In addition, pursuant to
standard open purchase orders with the Company for the purchase of the Original
Vortex, these customers or component manufacturers for such customers, along
with others, have agreed to promote the Company's A3D technology. During the
first two quarters of 1998, the Company recorded revenues of $7.0 million, the
vast majority of which consisted of sales of its Original Vortex.

     Earlier in 1998, the Vortex AU8820 received Microsoft's Windows Hardware
Quality Labs ("WHQL") certification. Microsoft's WHQL certification virtually
ensures that customers integrating the Vortex AU8820 chip into their audio
subsystems will receive quality approval from Microsoft which is a key
differentiation for consumers looking for quality in PC products.
   
     The Company also completed some significant financing transactions in 1997
and early 1998. The Company completed the sale of Series A Shares and issued the
Series A Warrants in March 1998. In June 1998, the Company exchanged the
outstanding balance of $31.5 million under its working capital line of credit
into Series B Shares with a conversion value of $39.375 million. Also in June
1998, the Company completed the sale of the Series C Shares, entered into a new
$40 million line of credit agreement and issued the Credit Warrants.
    
     In the consumer electronics field, the Company has announced licensing
deals with Zoran Corporation, LSI Logic Corporation and Yamaha Corporation for
its A3D Surround technology. Advent has introduced its Powered Partners speaker
product line, which is based on Aureal's VSP901 ProLogic chip. The Company
continues to invest significant resources in the development of semiconductor
products targeted for the multi-channel mini-component and audio receiver
markets that will include the Company's A3D Surround technology for Dolby
ProLogic, Dolby Digital and MPEG II audio.

     The Company's revenues for 1997 were primarily related to the up-front
licensing fees for its A3D technologies, the sale of a modest number of VSP901
chips and the initial shipments of the Vortex AU8820 chip. The Company has begun
volume shipments of its Vortex AU8820 device in 1998.

     The Company, in May 1996, acquired 100% ownership of Crystal River
Engineering, Inc., a leader in the field of 3D audio technology. This merger of
resources has enabled Aureal to offer hardware and software solutions optimized
for 3D audio presentation.

     In August 1995, the Company announced that it was divesting its multimedia
components business to implement its current business plan based on development
and sale of software and semiconductor solutions providing advanced audio for
the PC and consumer electronics markets. The Company was active in the business
of selling multimedia components for the retail market from its founding in 1990
through mid-1995 (operating as Media Vision Technology Inc.). Since November
1995, the Company has operated under its current name, which was formally
changed at its Annual Stockholders' Meeting in May 1996.

     The Company is headquartered in Fremont, California in a leased 36,000
square foot building. As of December 28, 1997, the Company had 81 employees. Of
this total, 47 were engaged in engineering functions, 23 were in sales and
marketing activities, and 11 were engaged in administrative support. Competition
for employees in the Company's industry is intense. None of the Company's
employees is represented by a labor union. The Company considers its relations
with its employees to be good.

                                  RISK FACTORS

     In addition to the other information in this Prospectus or incorporated
herein by reference, the following factors should be considered carefully in
evaluating the Company and its business before purchasing the Shares offered
hereby:

     HISTORY OF LOSSES AND ACCUMULATED DEFICIT; EXPECTATION OF FUTURE LOSSES.
The Company emerged from bankruptcy in December 1994. Since that time, the
Company has recorded an accumulated deficit of $162 million as of June 28, 1998
comprised of $150 million of incurred losses (including $11 million in 1998, $18
million in 1997, $17 million in 1996 and $104 million in 1995) from (1) its
previous retail products operations in 1995, (2) the research and development
phases of its advanced audio technologies business operations in 1996 and 1997,
and (3) the start of its sales efforts for its advanced audio products in the
first half of 1998, and $12 million of accretion and dividends on preferred
stock. While the majority of the Company's revenues in 1996 and 1997 were
generated through technology licensing transactions, the Company anticipates
that the majority of its revenues will come from the sale of audio products in
1998 and future years. There can be no assurance that the Company will be able
to sell significant volumes of its products in the future, and the Company's
ability to attain profitability or generate positive cash flows is dependent
thereon.

     NEW TECHNOLOGIES AND PRODUCTS DEVELOPED WITH NEW TECHNOLOGIES. The
Company's success depends on its ability to develop and market new technologies
aimed at advancing the level of audio quality in the PC and consumer electronics
devices. With respect to the PC market, audio technology is shifting from
utilization of the ISA bus to utilization of the more advanced (higher
band-width) PCI bus. This change enables advanced digital audio functionality
including positional 3D audio, streaming audio and higher quality presentation.
There can be no assurance that the shift from ISA-based audio to PCI-based audio
will occur in a time frame for the Company to benefit from its PCI-based
products and technologies. As new technologies are developed, there can be no
assurance that markets will develop for them, or that markets will develop on a
timely basis for the Company to benefit therefrom.

     The success of new products depends on a number of factors, including
timely completion of product development, market acceptance of the Company's and
its customers' new products and the Company's ability to offer new products at
competitive prices. Incorporating the Company's new products into its OEM
customers' new product designs requires the anticipation of market trends and
performance and functionality requirements of OEMs, the development and
production of products that meet the timing and pricing requirements of OEMs and
the production of products that can be available in a timely manner consistent
with the OEMs' development and production schedules. A failure in any of these
areas could have a material adverse effect on the Company's business, financial
condition and results of operations.

     Each successive generation of microprocessors has provided increased
performance, which could in the future result in a microprocessor capable of
performing advanced audio functions to an extent that the need or preference for
the Company's products could be diminished or eliminated. Conversely, each new
generation of technology, including digital audio technology, generally requires
increased processing power. In this regard, Intel Corporation has created the
MMX functionality with its Pentium line of processors and is promoting the
processing power of MMX for data and signal intensive functions such as graphics
and audio processing. The Company believes that advanced audio processing, done
in conjunction with either video or graphics processing is best performed with a
separate accelerator chip in addition to the host processor. There can be no
assurance that the increased capabilities of microprocessors in the future will
not adversely affect demand for the Company's products.

     PRODUCT CONCENTRATION AND EXPANSION OF BUSINESS MODEL. Substantially all of
the Company's revenues are related to advanced audio solutions for the PC and
consumer electronics markets, and the Company expects this to continue for the
foreseeable future. The Company is just embarking on an expansion of its
semiconductor business model to provide for an increased number of audio related
products including audio cards and audio communications combination cards. This
expansion may require additional working capital funds to provide for
incremental inventory as well as broader marketing programs. The failure of this
market to continue to grow, any reduction in demand as a result of increased
competition in this market, technological change, failure by the Company to
introduce new versions of products acceptable to the marketplace or other
similar factors would have a material adverse effect on the Company's results of
operations.

     COMPETITION AND PRICING PRESSURES. The markets in which the Company
competes are intensely competitive and are characterized by evolving industry
standards resulting in relatively short product life cycles, significant pricing
and performance improvement pressures and frequent new product introductions.
The Company expects competition to increase in the future from existing
competitors and from other companies that may enter the markets with products
that may be less costly or provide higher performance or additional features.
The Company is unable to predict the timing and nature of any such competitive
product

                                       10
<PAGE>   11

offerings. In general, product prices in the semiconductor industry have
decreased over the life of a particular product. The willingness of prospective
customers to design the Company's products into their products depends to a
significant extent upon the ability of the Company to price its products at
levels that are cost-effective for such customers. As the markets for the
Company's products mature and competition increases, the Company anticipates
that prices for its products will generally decline over time. If the Company is
unable to reduce its costs sufficiently to offset declines in product prices or
is unable to introduce new, higher performance products with higher product
prices, the Company's results of operations could be materially adversely
affected.

     The Company anticipates that it will compete for the development of new
technologies and for the sale of semiconductor products with a number of
companies who have more extensive resources including financial, manufacturing,
technical, marketing and distribution. In addition, some of those firms have
greater intellectual property rights, broader product lines and longer-standing
relationships with customers than the Company. The Company's competitors may
also include a number of emerging companies.

     DEPENDENCE ON CREDIT FACILITY. Because it has not been profitable to date,
the Company has funded its losses through a combination of equity and debt
financing. In June 1998, the Company entered into a credit facility (the "Credit
Facility") with Goldman Sachs Credit Partners LP and the Technology Finance
Division of Transamerica Business Credit Corporation, which provides for an
aggregate maximum borrowing of $40 million. The interest rate on the Credit
Facility is generally the prime rate plus 3% to 5%. Accordingly, while the
Credit Facility provides the Company with working capital, the high cost of
servicing any borrowing thereunder could negatively effect the Company's
liquidity. There can be no assurance that this line of credit will be sufficient
to meet the Company's needs. In the event the Company is required to secure
additional capital, there can be no assurance that such capital will be
available on acceptable terms or at all. The Company's inability to secure such
potential future financing, if necessary, would have a material adverse effect
on the Company's business, financial condition and results of operations.

     FACTORS INHIBITING TAKEOVER. The Company is subject to the provision of
Section 203 of the Delaware General Corporation Law, which imposes certain
restrictions on the ability of a third party to effect an unsolicited change in
control of the Company. In addition, the Company's Amended and Restated
Certificate of Incorporation does not provide for cumulative voting in the
election of directors, and certain provisions of the Company's Amended and
Restated Certificate of Incorporation and Bylaws, including the provision which
divides the Board into three separate classes, may have the effect of delaying
or preventing changes in control or management of the Company.

     TRADING IN THE NON-NASDAQ OVER-THE-COUNTER MARKET; DISCLOSURE RELATING TO
LOW PRICED STOCK. The Company's Common Stock trades only on the OTC Bulletin
Board, and the trading volume has been generally light. The Company does not
currently meet the requirements of the Nasdaq National Market ("Nasdaq") or
other national stock exchanges. There can be no assurance that the Company in
the future will meet such listing requirements or that it will be accepted for
trading on any such national exchange.

     Because the Company's Common Stock trades on the non-Nasdaq
over-the-counter market, an investor may find it more difficult to dispose of,
or to obtain accurate quotations as to the market value of, the Company's Common
Stock. In addition, because the Company's Common Stock is not listed on Nasdaq,
trading in its Common Stock is also subject to certain rules promulgated under
the Exchange Act, which require additional disclosure by broker-dealers in
connection with any trades involving a stock defined as a penny stock
(generally, any non-Nasdaq equity security that has a market price of less than
$5.00 per share, subject to certain exceptions). The additional burdens imposed
upon broker-dealers by such requirements may discourage broker-dealers from
effecting transactions in the Company's Common Stock, and may limit the ability
of purchasers of the Company's Common Stock to resell such securities in the
secondary market.

     RISK OF ADDITIONAL SHARES SOLD IN THE PUBLIC MARKET. Because the holders of
the Series A Shares and the Series C Shares may convert such shares into shares
of the Company's Common Stock at variable conversion prices, the exact number of
shares of Common Stock which the Company may issue upon conversion of Series A
Shares and Series C Shares is not currently known, and may fluctuate based on
the market value of the Company's Common Stock. Because of the variable
conversion price feature of the Series A Shares and Series C Shares, holders of
such shares may have incentive to take certain actions, including shorting the
Company's Common Stock, to decrease the market price of such Common Stock. Upon
a decrease in the market price of the Company's Common Stock, holders of the
Series A Shares and Series C Shares may elect to convert such shares at the
variable conversion price and thereby receive a greater number of shares of the
Company's Common Stock. Short selling is illegal if used to manipulate the price
of a company's securities for profit, and the Company has no knowledge that any
holders of Series A Shares or Series C Shares intends to take any action that
may cause the price of the Company's Common Stock to fall. However, there can be

                                       11
<PAGE>   12

no assurance that holders of the Company's Series A Shares or Series C Shares
will not short the Company's Common Stock or take such other actions, the effect
of which may be to drive down the market price of the Company's Common Stock.

     CONCENTRATION OF STOCK OWNERSHIP. Currently, three parties control
approximately 75% of the outstanding Common Stock, each of whom controls at
least 10% individually. There can be no assurance that the liquidity of the
market for the Common Stock will be maintained at or increase over its current
levels, and the trading price for the Common Stock may be influenced by the
volume and liquidity of the market for the Common Stock. Sales of a large
percentage of the Company's total outstanding Common Stock may have an adverse
effect on the market price for such securities.

     DEPENDENCE ON FOUNDRIES. The Company is a "fabless" semiconductor firm that
depends on outside manufacturing resources for production of all of its
semiconductor products. Currently the Company utilizes two foundries, one
domestic and one foreign, for production of its existing products. Both of these
foundries have indicated to the Company that they have the manufacturing
availability to provide for the Company's planned production of each of its
products for the next 12 months; however the Company's production relationship
with each foundry is based only upon purchase orders, and there is no assurance
that either foundry will continue to provide adequate manufacturing capacity to
the Company for its current level of production or any potential increases in
production levels. In the event that either or both foundries cease to
manufacture the Company's semiconductor products, the Company would have to
contract with alternative foundries. There can be no assurance that the Company
would be able to contract with alternative foundries in a timely manner or at
all. The failure to do so would have a material adverse effect on the Company's
business, financial condition and results of operations.

     The manufacture of semiconductor products is a highly complex and precise
process. Minute levels of contaminants in the manufacturing environment, defects
in the masks used to print circuits on wafers, difficulties in the fabrication
process or other factors can cause a substantial percentage of wafers to be
rejected or a significant number of die on each wafer to be non-functional. Many
of these problems are difficult to diagnose and potentially time-consuming or
expensive to remedy. There can be no assurance that the Company's foundries will
not experience irregularities or adverse yield fluctuations in the manufacturing
processes of the Company's products in the future, which could have a material
adverse effect on the Company's business, financial condition and results of
operations.

     DEPENDENCE ON KEY PERSONNEL. The Company's success depends to a significant
extent upon continued services of key engineering, marketing, sales and
management personnel. The Company's employees may voluntarily terminate their
employment with the Company at any time. The Company recognizes the value of the
contributions of each of its employees and has developed compensation programs,
including stock option plans for the granting of options to all employees,
designed to retain its employees. Competition for such employees is intense, and
the loss of the services of such employees could have a material adverse effect
on the Company's business, financial condition and results of operations.

     DEPENDENCE ON PROPRIETARY TECHNOLOGY. The Company's ability to compete
successfully will depend, in part, on its ability to protect its proprietary
technology. The Company relies on a combination of patents, trade secrets,
copyright and trademark laws, nondisclosure agreements and other contractual
provisions and technical measures to protect its proprietary rights. There can
be no assurance that such measures will be adequate or safeguard the proprietary
technology underlying the Company's products, or that its agreements with
employees, consultants and others who participate in the development of its
products will not be breached, that the Company will have adequate remedies for
any breach or that the Company's proprietary information or trade secrets will
not otherwise become known. Moreover, notwithstanding the Company's efforts to
protect its intellectual property, there can be no assurance that competitors
will not be able to develop products that are equal or superior to the Company's
products without infringing any of the Company's intellectual property rights.
In addition, effective protection of intellectual property rights may be
unavailable or limited in certain countries. Accordingly, there can be no
assurance that the Company's means of protecting its intellectual property will
be adequate or that the Company's competitors will not independently develop
similar technologies or products.

     Although the Company does not believe that its products infringe the
proprietary rights of any third parties, there can be no assurance that
infringement or invalidity claims (or claims for indemnification resulting from
infringement claims) will not be asserted against the Company or that any such
assertions will not materially adversely affect the Company's business,
financial condition or results of operations. Irrespective of the validity or
the successful assertion of such claims, the Company could incur significant
costs with respect to the defense thereof which could have a material adverse
effect on the Company's business, financial condition or results of operations.

                                       12
<PAGE>   13

     In February 1998, the Company was served with a lawsuit for patent
infringement filed by Creative Technology Ltd., a Singapore corporation
("Creative"), and its subsidiary, E-MU Systems, Inc., a California corporation
("E-MU"), in the U.S. District Court, Northern District of California. The
lawsuit alleges that the Company's Original Vortex infringes on a patent that
describes a specific implementation for an electronic musical instrument
designed by E-MU. Creative and E-MU seek, among other things, a preliminary and
permanent injunction against continuing acts of infringement by the Company and
an accounting of damages plus interest. In response, the Company filed a motion
for summary judgment. In August 1998, E-MU and Creative filed a motion for a
preliminary injunction with respect to the Company's Original Vortex and the
Vortex 2. The Company believes that the actions filed by Creative and E-MU are
without merit and is vigorously defending against these actions.

     Litigation may be necessary to resolve the claims asserted by Creative and
E-MU and any other claims asserted in the future to defend against claims of
infringement or invalidity or to enforce and protect the Company's intellectual
property rights. There can be no assurance that the Company will prevail in any
such litigation and any such litigation, whether or not determined in the
Company's favor or settled by the Company, would be costly and would divert the
efforts and attention of the Company's management and technical personnel from
normal business operation, which could have a material adverse effect on the
Company's business, financial condition and results of operations. Adverse
determinations in litigation could result in the loss of the Company's
proprietary rights, subject the Company to significant liabilities, require the
Company to seek licenses from third parties or prevent the Company from
licensing its technology, any of which could have a material adverse effect on
the Company's business, financial condition and results of operations.

     YEAR 2000 COMPLIANCE. The Company uses a number of computer software
programs and operating systems in its internal operations, including
applications used in financial business systems and various administration
functions. To the extent that these software applications contain source code
that is unable to appropriately interpret the upcoming calendar year "2000,"
some level of modification or even possible replacement of such source code or
applications could be necessary. Given the information known at this time about
the Company's systems, it is currently not anticipated that such "Year 2000"
costs will have a material impact on the Company. The Company is not aware that
any of its key suppliers or customers are not fully "Year 2000" compliant. If
any of its key suppliers or customers are not yet fully "Year 2000" compliant,
there can be no assurance that such non-compliance would not have a material
adverse effect on the Company's business, financial condition and results of
operations.

                                 USE OF PROCEEDS

     The Company will receive the proceeds from the exercise of the Series A
Warrants and the Credit Warrants, if any, and expects to use such proceeds, if
any, for general working capital purposes. The Company will not receive any
proceeds from conversions of the Series A Shares, Series B Shares and Series C
Shares and all proceeds from any sales of such Shares will go to the
respectively Selling Stockholders to be used for their own purposes.

                              SELLING STOCKHOLDERS

     The Selling Stockholders will hold the Shares that are issuable upon

*    Less than one percent

(1)  Beneficial ownership is determined in accordance with the rules of the
     Commission. In computing the number of shares beneficially owned by a
     person and the percentage ownership of that person, shares of the Company's
     Common Stock subject to options and warrants held by that person that are
     currently exercisable or become exercisable within 60 days of August 17,
     1998 are deemed outstanding. However, such shares are not deemed
     outstanding for purposes of computing the percentage ownership of any other
     person. This table is based upon information supplied by officers,
     directors and principal stockholders. Except as otherwise indicated, the
     Company believes that the persons or entities named in the table have sole
     voting and investment power with respect to all shares of the Company's
     Common Stock shown as beneficially owned by them, subject to community
     property laws where applicable.

(2)  The number of Shares set forth in the table represents an estimate of the
     number of Shares to be offered by the Selling Stockholders and assumes the
     exercise of all Series A Warrants and Credit Warrants issued as described
     in this Prospectus. Pursuant to the Company's agreement with the Series A
     Selling Stockholders as set forth in the Series A Financing Agreements, the
     number of shares of Common Stock registered by this Registration Statement
     equals approximately 188% of the shares of Common Stock that would be
     issued had the Series A Shares been converted on April 13, 1998. The actual
     number of shares of Common Stock issuable upon conversion of Series A
     Shares and exercise of the Series A Warrants issued or issuable is
     indeterminate, is subject to adjustment and could be materially more than
     such estimated number depending on factors which cannot be predicted by the
     Company at this time, including the future market price of the Common
     Stock. The actual number of shares of Common Stock offered hereby, and
     included in the Registration Statement of which this Prospectus is a part,
     includes such additional number of shares of Common Stock as may be issued
     or issuable upon conversion of the Series A Shares and exercise of the
     Series A Warrants by reason of the floating rate conversion price mechanism
     or other adjustment mechanisms described therein, or by reason of any stock
     split, stock dividend or similar transaction involving the Common Stock, in
     order to prevent dilution, in accordance with Rule 416 under the Securities
     Act.

     Pursuant to the Company's agreement with the Series C Selling Stockholders
     as set forth in the Series C Financing Agreements, the number of Shares
     registered by this Registration Statement equals approximately 150% of the
     Shares that would be issued had the Series C Shares been converted on
     August 17, 1998. The actual number of Shares issuable upon conversion of
     Series C Shares is indeterminate, is subject to adjustment and could be
     materially more than such estimated number depending on factors that cannot
     be predicted by the Company at this time, including the future market price
     of the Company's Common Stock. The actual number of Shares offered hereby,
     and included in the Registration Statement of which this Prospectus is a
     part, includes such additional number of Shares as may be issued or
     issuable upon conversion of the Series C Shares and by reason of the
     floating rate conversion price mechanism or other adjustment mechanisms
     described in the Series C Certificate of Designation, or by reason of any
     stock split, stock dividend or similar transaction involving the Company's
     Common Stock, in order to prevent dilution, in accordance with Rule 416
     under the Securities Act.

                              PLAN OF DISTRIBUTION

     The Shares being offered by the Selling Stockholders or their respective
pledgees, donees, transferees or other successors in interest, will be sold in
one or more transactions (which may involve block transactions) on the OTC
Bulletin Board or on such other market on which the Common Stock may from time
to time be trading, in privately-negotiated transactions, through the writing of
options on the Shares, short sales or any combination thereof. The sale price to
the public may be the market price prevailing at the time of sale, a price
related to such prevailing market price or such other price as the Selling
Stockholders determine from time to time.

     The Selling Stockholders or their respective pledgees, donees, transferees
or other successors in interest, may also sell the Shares directly to market
makers acting as principals and/or broker-dealers acting as agents for
themselves or their customers. Brokers acting as agents for the Selling
Stockholders will receive usual and customary commissions for brokerage
transactions, and market makers and block purchasers purchasing the Shares will
do so for their own account and at their own risk. It is possible that a Selling
Stockholder will attempt to sell shares of Common Stock in block transactions to
market makers or other purchasers at a price per share which may be below the
then market price. There can be no assurance that all or any of the Shares
offered hereby will be issued to, or sold by, the Selling Stockholders. The
Selling Stockholders and any brokers, dealers or agents, upon effecting the sale
of any of the Shares offered hereby, may be deemed "underwriters" as that term
is defined under the Securities Act or the Exchange Act, or the rules and
regulations thereunder.

     The Selling Stockholders and any other persons participating in the sale or
distribution of the Shares will be subject to applicable provisions of the
Exchange Act and the rules and regulations thereunder, which provisions may
limit the timing of purchases and sales of any of the Shares by the Selling
Stockholders or any other such person. The foregoing may affect the
marketability of the Shares.

     The Company has agreed to indemnify in certain circumstances the Selling
Stockholders against certain liabilities, including liabilities under the
Securities Act. The Selling Stockholders have agreed to indemnify in certain
circumstances the Company against certain liabilities, including liabilities
under the Securities Act.

     The Company has agreed to use its best efforts to keep the Registration
Statement, of which this Prospectus constitutes a part, effective until the
earlier of (i) the date on which the Selling Shareholders can sell all the
Shares pursuant to Rule 144 of the Security Act (without regard to volume
limitations) or (ii) when all of the Shares have been resold pursuant to Rule
144 or an effective registration statement.

                                  LEGAL MATTERS

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     As permitted by Section 145 of the Delaware General Corporation Law (the
"DGCL"), the Registrant's Certificate of Incorporation provides that each person
who is or was or who had agreed to become a director or officer of the
Registrant or who had agreed at the request of the Registrant's Board of
Directors or an officer of the Registrant to serve as an employee or agent of
the Registrant or as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall be
indemnified by the Registrant to the full extent permitted by the DGCL or any
other applicable laws. Such Certificate of Incorporation also provides that no
amendment or repeal of such Certificate of Incorporation shall apply to or have
any effect on the right to indemnification permitted or authorized thereunder
for or with respect to claims asserted before or after such amendment or repeal
arising from acts or omissions occurring in whole or in part before the
effective date of such amendment or repeal.

     The Registrant's Bylaws provide that the Registrant shall indemnify to the
full extent authorized by law any person made or threatened to be made a party
to an action or a proceeding, whether criminal, civil, administrative or
investigative, by reason of the fact that he, his testator or intestate was or
is a director, officer or employee of the Registrant or any predecessor of the
Registrant or serves or served any other enterprise as a director, officer or
employee at the request of the Registrant or an predecessor of the Registrant.
The Registrant's Bylaws also provide that the Registrant may enter into one or
more agreements with any person which provides for indemnification greater or
different than that provided in such Certificate of Incorporation.

     The Registrant has entered into indemnification agreements with its
directors and its officers.

     The Registrant intends to purchase and maintain insurance on behalf of any
person who is a director or officer against any loss arising from any claim
asserted against him and incurred by him in any such capacity, subject to
certain exclusions.

     See also the undertakings set out in response to Item 17 herein.

ITEM 17.  UNDERTAKINGS.

     (a)  The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement;

               (i)  To include any prospectus required by section 10(a)(3)of the
Securities Act;

               (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement;

               (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement; provided,
however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.

          (2)  That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bonafide offering thereof.

                                      II-2
<PAGE>   23

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     (b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c)  The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (d)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers, and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in The
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

     (e)  The undersigned Registrant hereby undertakes that:

          (1)  For the purposes of determining any liability under the
Securities Act, the information omitted from the form of prospectus filed as
part of this registration statement in reliance upon Rule 430A and contained in
a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
or 497(h) under the Securities Act shall be deemed to be part of the
registration statement as of the time it was declared effective.

          (2)  For the purposes of determining any liability under the
Securities Act, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
