The information in this prospectus is not complete and may be changed. These

SUBJECT TO COMPLETION DATED NOVEMBER __, 1998

13,387,449 SHARES (issuable upon conversion of Series A Preferred Stock)

19,954,137 SHARES (issuable upon conversion of Series C Preferred Stock)

                            AUREAL SEMICONDUCTOR INC.
                                  COMMON STOCK
                               ($0.001 Par Value)

     Pursuant to the registration statement of which this prospectus is a part,
we are registering 33,341,586 shares (the "Shares") of our Common Stock, par
value $0.001 per share (the "Common Stock"). Of the Shares offered by this
prospectus, we are registering 13,387,449 of such Shares pursuant to our
registration obligations to the holders of Series A Preferred Stock (the "Series
A Shares"), and an additional 19,954,137 of such Shares pursuant to our
registration obligations to the holders of Series C Preferred Stock (the "Series
C Shares"). We previously registered on Form S-2 (Registration no. 333-62083)
(the "Prior Registration Statement") a total of 7,350,000 shares of our Common
Stock for issuance upon conversion of the Series A Shares and the Series C
Shares. Contractual obligations to the holders of Series A Shares and the
holders of the Series C Shares require us to register a certain number of our
Common Stock to be issued to the holders of Series A Shares and the holders of
Series C Shares upon the conversion of their preferred stock into our Common
Stock. The conversion mechanism of the Series A Shares and the Series C Shares
is tied to the current market price for our Common Stock. As a result of the
recent decline in the market price of our Common Stock, we are required to
register the Shares to cover the increased number of shares of Common Stock into
which the Series A Shares and the Series C Shares may convert. For a more
complete description of the Series A Shares and the Series C Shares and the
transactions under which they were issued, please see the Prior Registration
Statement.

     We 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 our outside counsel and independent
accountants, but excluding transfer or other taxes and other costs and expenses
incident to the issuances of the Shares.

     Our Common Stock is quoted on the Over-the-Counter Electronic Bulletin
Board (the "OTC Bulletin Board") under the symbol "AURL". On October 30, 1998,
the average of the closing bid and asking prices of our Common Stock was $0.525.
The 33,341,586 Shares being offered by this prospectus represent approximately
32% of the Company's total equity securities, recognizing that the Shares being
registered are subject to issuance upon the conversion of the Series A Shares
and the Series C Shares. 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.

prospectus is truthful or complete. Any representation to the contrary is a
criminal offense.

                                   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 manufactures 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.

                                       1
<PAGE>   6

     In July 1998, the Company announced that it had entered into a strategic
alliance with Diamond Multimedia Systems, Inc. ("Diamond"), a leader in the
interactive multimedia market, to co-develop and market PC audio solutions for
the PC consumer and game markets. Pursuant to this alliance, Diamond has 
announced and commenced shipping two new audio add-in card products for the 
PC market, the Monster Sound 300 (incorporating the Aureal Vortex 2 and A3D 
2.0) and the Sonic Input (incorporating the Original Vortex and A3D).

     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. With these design wins, the foregoing
manufacturers 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 three quarters
of 1998, the Company recorded revenues of $14.6 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.

</TABLE>

We generated the majority of our revenues in 1997 and 1996 through technology
licensing transactions. We anticipate that the majority of our revenues will
come from the sale of advanced audio products in 1998 and future years. As of
September 27, 1998, we have sold $14.6 million of advanced audio products during
1998. We may not be able to sell significant volumes of our advanced audio
products in the future. If we do not sell significant volumes of our advanced
audio products, we will not be profitable.

NEW TECHNOLOGIES AND PRODUCTS DEVELOPED WITH NEW TECHNOLOGIES. Our success
depends on our ability to develop and market new technologies aimed at advancing
the level of audio quality in personal computers 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 (high band-width)
PCI bus. This change enables advanced digital audio functionality including
positional 3D audio, streaming audio and higher quality audio presentation.
However, we may not be able to benefit from the shift from ISA-based audio to
PCI-based audio because the market may not accept the new format in time for us
benefit. The success of our new audio products depends on various factors
including: 

o  timely completion of product development; 
o  market acceptance of our new products and those of our customers; and 
o  our ability to offer new products at competitive prices.

In addition, a number of factors affect our ability to incorporate our new
products into our Original Equipment Manufacturers' new designs. In order to be
successful in incorporating our designs into the new products developed by our
OEMs, we must:

o  anticipate market trends;
o  anticipate the performance and functionality requirements of our current and 
   potential customers;
o  develop and produce products that meet the timing and pricing requirements of
   our current and potential customers; and
o  produce products that can be available in a timely manner consistent with our
   current and potential customers' development and production schedules.


                                       4
<PAGE>   9

A failure in any of these areas could materially adversely affect our business,
financial condition and results of operations.

     We also face the risk that new generations of microprocessors that are
capable of performing the function of advanced audio products will greatly
reduce demand for our products. 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
could diminish or eliminate the need or preference for our products. In
addition, each new generation of technology, including digital audio technology,
generally requires increased processing power. For example, 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. We believe 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. However, the increased capabilities of microprocessors in the future
may adversely affect demand for our products.

PRODUCT CONCENTRATION AND EXPANSION OF BUSINESS MODEL. Substantially all of our 
revenues are related to advanced audio solutions for the PC and consumer
electronics markets, and we expect this to continue for the foreseeable future.
We are currently embarking on an expansion of our semiconductor business model
to provide for an increased number of audio related products including audio
cards and audio communications combination cards. We may require additional
working capital funds for this expansion to provide for incremental inventory as
well as broader marketing programs. A number of factors may limit the success of
our expansion and could each negatively impact our business and results of
operations. These factors include:

o  the failure of this market to continue to grow;
o  reduction in demand as a result of increased competition in this market;
o  unexpected technological change; and
o  our potential failure to introduce new versions of products acceptable to 
   the market.

COMPETITION AND PRICING PRESSURES. The markets in which we compete are intensely
competitive and are characterized by evolving industry standards that result in:

o  relatively short product life cycles;
o  significant pressure to improve price and performance; and
o  frequent new product introductions.

We expect competition to increase 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 than the products we currently
offer. However, we are unable to predict the timing and nature of any such
competitive product offerings. In addition, product prices in the semiconductor
industry generally decrease over the life of particular products. The
willingness of prospective OEM customers to design our products into their
products depends to a significant extent upon our ability to price our products
at levels that are cost-effective for these customers. As the markets for our
products mature and competition increases, we anticipate that prices for our
products will generally decline over time. If we are unable to reduce our costs
sufficiently to offset declines in our product prices, or if we are unable to
introduce new, higher performance products with higher product prices, our
results of operations could be materially adversely affected. We anticipate that
we 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 these competitors have greater intellectual
property rights, broader product lines and longer-standing relationships with
their customers than do we. In addition to our established competitors, we may
also face competition from a number of emerging companies.

DEPENDENCE ON CREDIT FACILITY. Because we have not been profitable to date, we
have had to fund our losses through a combination of equity and debt financing.
In June 1998, we entered into a credit facility (the "Credit Facility") with
Goldman Sachs Credit Partners LP and the Technology Finance Division of
Transamerica Business Credit Corporation. The Credit Facility 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 us with needed working capital, the high cost of
servicing any borrowing under the Credit Facility could negatively affect our
liquidity. In addition, the Credit Facility may not be sufficient to meet our
working capital requirements. In the event we must secure additional capital,
there can be no assurance that such capital will be available on acceptable
terms or at all. Our inability to secure such potential future financing, if
necessary, would have a material adverse affect on our business, financial
condition and results of operations.

FACTORS INHIBITING TAKEOVER. We are subject to the provision of Section 203 of
the Delaware General Corporation Law. These provisions impose certain
restrictions on the ability of a third party to acquire us without our consent.
In addition, our Amended and Restated Certificate of Incorporation does not
provide for cumulative voting in the election of directors. Further, certain
provisions of our Amended and Restated Certificate of Incorporation and Bylaws,
including the provision that divides the Board into three separate classes, may
have the effect of delaying or preventing changes in control or changes of our
management.

TRADING IN THE NON-NASDAQ OVER-THE-COUNTER MARKET; DISCLOSURE RELATING TO LOW
PRICED STOCK. Our Common Stock trades only on the Over-the-Counter Bulletin
Board. We do not currently meet the requirements for listing on the Nasdaq
National Market ("Nasdaq") or any national stock exchange. In addition, in the
future we may still not meet such listing requirements, or we may not ever be
accepted for trading on any national exchange. Because our Common Stock trades
on the non-Nasdaq over-the-counter market, an investor may find it more
difficult to sell, or to obtain accurate quotations as to the market value of,
our Common Stock. Furthermore, because our Common Stock is not listed on Nasdaq,
trading in our Common Stock is also subject to certain rules promulgated under
the Securities and Exchange Act of 1934, as amended. These rules require
additional disclosure by broker-dealers in connection with any trades involving
a stock defined as a penny stock (generally, any non-Nasdaq listed equity
security that has a market price of less than $5.00 per share, subject to
certain exceptions); our Common Stock meets this definition. The additional
burdens imposed upon broker-dealers by such requirements may discourage
broker-dealers from affecting transactions in the our Common Stock, and may
limit the ability of purchasers of our Common Stock to resell our stock 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 these securities into shares
of our Common Stock at variable conversion prices, we do not currently know the
exact number of shares of our Common Stock that we may be required to issue upon
conversion of the Series A Shares and the Series C Shares. Further, this number
may fluctuate based on the market value of our 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 our Common Stock, to decrease the market price of our Common Stock. By
decreasing the market price for our Common Stock, the holders of the Series A
Shares and Series C Shares can convert their shares at the lower variable
conversion price and thereby receive a greater number of shares of our Common
Stock. Short selling is illegal if used to manipulate the price of a company's
securities for profit. We have no knowledge that any holder of Series A Shares
or Series C Shares intends to take any action that may cause the price of our
Common Stock to fall. However, we can not assure you that holders of the Series
A Shares or the Series C Shares will refrain from short selling our Common Stock
or will refrain from taking other actions that would drive down the market price
of our Common Stock.

CONCENTRATION OF STOCK OWNERSHIP. Currently, three parties collectively control
approximately 75% of our outstanding Common Stock, each of whom controls at
least 10% individually. We do not know if the liquidity of the market for our
Common Stock will maintain, or increase from, its current levels. In addition,
the volume and liquidity of the market for our Common Stock may influence the
trading price for our Common Stock. Sales of a large percentage of our total
outstanding Common Stock may have an adverse affect on the market price for such
securities.

DEPENDENCE ON FOUNDRIES. We are a "fabless" semiconductor firm that depends on
outside manufacturing resources for production of all of our semiconductor
products. Currently, we utilize two semiconductor foundries, one domestic and
one foreign, for production of our existing products. Both of these foundries
have indicated to us that they have the manufacturing availability to provide
for our planned production of each of our products for the next 12 months;
however our production relationship with each foundry is based only upon
purchase orders. Consequently, either foundry may not continue to adequately
provide manufacturing capacity to us for our current level of production or any
potential increases in our production levels. In the event that either or both
foundries cease to manufacture our semiconductor products, we would have to
contract with alternative foundries. However, we may not be able to timely
contract with alternative foundries or to contract with them at all. Such a
situation could materially adversely affect our 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 and other factors can cause a substantial percentage of wafers to be
rejected or a significant number of die on each wafer not to function. Many of
these problems are difficult to diagnose and potentially time-consuming or
expensive to remedy. The foundries that we employ may, in the future, experience
such irregularities or adverse yield fluctuations in the manufacturing processes
of our products. Such an event could materially adversely affect our business,
financial condition and results of operations.


                                       6
<PAGE>   11

DEPENDENCE ON KEY PERSONNEL. Our success depends to a significant extent upon
the continued services of key engineering, marketing, sales and management
personnel. Our employees may voluntarily terminate their employment with us at
any time. We recognize the value of the contributions of each of our employees,
and we have developed compensation programs, including stock programs open to
all employees, designed to retain our employees. However, competition for such
employees is intense, and the loss of the services of such employees could have
a material adverse affect on the our business, financial condition and results
of operations.

DEPENDENCE ON PROPRIETARY TECHNOLOGY. Our ability to compete successfully will
depend, in part, on our ability to protect our proprietary technology. We rely
on a combination of patents, trade secrets, copyright and trademark laws,
nondisclosure agreements and other contractual provisions and technical measures
to protect our proprietary rights. Nevertheless, there can be no assurance that
such measures will be adequate or safeguard the proprietary technology
underlying our products. In addition employees, consultants and others who
participate in the development of our products may breach their agreements with
us regarding our intellectual property, and we may not have adequate remedies
for any such breach. We also realize that our proprietary information and trade
secrets may become known through other means not currently foreseen by us.
Moreover, notwithstanding our efforts to protect our intellectual property, our
competitors may be able to develop products that are equal or superior to our
products without infringing on any of our intellectual property rights. In
addition, we may not be able to effectively protect our intellectual property
rights in certain countries.

     Although we do not believe that our products infringe the proprietary 
rights of any third parties, third parties may still assert infringement or
invalidity claims (or claims for indemnification resulting from infringement
claims) against us. Such assertions could materially adversely affect our
business, financial condition and results of operations. In addition,
irrespective of the validity or the successful assertion of such claims, we
could incur significant costs in defending against such claims. In defending
such claims we could incur expenses and waste resources that could have a
material adverse affect on our business, financial condition and results of
operations.

     In February 1998, Creative Technology Ltd., a Singapore corporation
("Creative"), and its subsidiary, E-MU Systems, Inc., a California corporation
("E-MU"), served us with a lawsuit for patent infringement that Creative and
E-MU had filed in the U.S. District Court, Northern District of California. The
lawsuit asserts that our 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 alleged continuing acts of infringement by us and an
accounting of damages plus interest. In response, we filed a motion for summary
judgment. In August 1998, E-MU and Creative filed a motion for a preliminary
injunction with respect to our Original Vortex and the Vortex 2. In October
1998, the court denied Creative's motion for preliminary injunction. In
addition, our motion for summary judgment was also denied. We believe that the
actions that Creative and E-MU filed are without merit, and we are vigorously
defending against these actions.

     Additional 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 our intellectual
property rights. There can be no assurance that we will prevail in any such
litigation. Also, any such litigation, whether or not determined in our favor or
settled by us, would be costly and would divert the efforts and attention of our
management and technical personnel from normal business operations; this could
have a material adverse affect on our business, financial condition and results
of operations. Adverse determinations in litigation could result in the loss of
our proprietary rights, subject us to significant liabilities, require us to
seek licenses from third parties or prevent us from licensing our technology,
any of which could have a material adverse affect on our business, financial
condition and results of operations.

YEAR 2000 COMPLIANCE. We use a number of computer software programs and
operating systems in our 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 current information, we currently do not
anticipate that such "Year 2000" costs will have a material impact upon us. We
have requested and obtained information regarding "Year 2000" compliance from
suppliers and providers of all of our mission critical software systems. Based
on the information we currently have, all mission critical systems appear to be
"Year 2000" compliant. We are currently contacting major vendors and customers
to obtain "Year 2000" compliance certificates. The failure of any of our key
suppliers or customers to be "Year 2000" compliant could have a material adverse
effect on our business, financial condition or results of operations.

                                 USE OF PROCEEDS

     The Company will not receive any proceeds from conversions of the Series A
Shares and Series C Shares and all proceeds from any sales of such Shares will
go to the respective Selling Stockholders to be used for their own purposes.

                              SELLING STOCKHOLDERS

     The Selling Stockholders will hold the Shares that are issuable upon
conversion of the Series A Shares and Series C Shares. The table below lists the
(i) Selling Stockholders, (ii) the number of Shares that each currently owns or
will own, assuming the conversion of the Series A Shares and the Series C Shares
on October 30, 1998 and the exercise of certain warrants, (iii) the number of
Shares subject to sale pursuant to this Registration Statement and (iv) the
number of shares of Common Stock each Selling Stockholder would own assuming the
sale by such Selling Stockholder of all Shares registered by this Registration
Statement.

     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. 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 150% of the
     shares of Common Stock that would be issued had the Series A Shares been
     converted on October 30, 1998. The actual number of shares of Common Stock
     issuable upon conversion of Series A Shares 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 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
     October 30, 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.

     Securities including both the TCW holdings and 7.8 million shares of the
     Equity Securities held by Oaktree as a fiduciary on behalf of a third party
     separate account of which Mr. Masson may be deemed a beneficial owner to
     the extent of any indirect pecuniary interest therein. Mr. Masson disclaims
     beneficial ownership of such shares of the Equity Securities.

                              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. Some or all of the Shares offered hereby may not 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 Stockholders can sell all the
Shares pursuant to Rule 144 of the Securities 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

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>   20

          (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.

Ladies and Gentlemen:

As legal counsel for Aureal Semiconductor Inc., a Delaware corporation (the
"Company"), we are rendering this opinion in connection with the preparation and
filing of a registration statement on Form S-2 (the "Registration Statement")
relating to the registration under the Securities Act of 1933, as amended, of
33,341,586 shares of Common Stock, par value $0.001 per share (the "Common
Stock"), to be issued by the Company upon conversion of shares of the Company's
Series A Preferred Stock and Series C Preferred Stock.

We have examined such instruments, documents and records as we deemed relevant
and necessary for the basis of our opinion hereinafter expressed. In such
examination, we have assumed the genuineness of all signatures and the
authenticity of all documents submitted to us as originals and the conformity to
the originals of all documents submitted to us as copies.

Based on such examination, we are of the opinion that the 33,341,586 shares of
Common Stock of the Company being registered pursuant to the Registration

accordance with the terms of the Company's Certificate of Designation of Series
A Preferred Stock or Certificate of Designation of Series C Preferred Stock, as
applicable, duly authorized shares, validly issued, fully paid, and
nonassessable.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement referred to above and the use of our name wherever it
appears in said Registration Statement.

This opinion is to be used only in connection with the issuance of the Common
Stock while the Registration Statement is in effect.
