CSR Offers QSound's MIDI Synthesizer in its MusiCore1 Audio Processor

CALGARY, ALBERTA AND CAMBRIDGE, UNITED KINGDOM, Apr 17
(MARKET WIRE) --
QSound Labs, Inc. (NASDAQ: QSND) and CSR today announced that CSR's
MusiCore1 is now being offered with mQSynth(TM), a powerful wavetable
MIDI synthesizer from QSound. CSR's MusiCore1 is the world's first fully
featured single-chip stereo audio processor with Bluetooth for mobile
phones. QSound's mQSynth provides MusiCore1 with the capability to
support a complete spectrum of audio features including polyphonic
ringtones, multi-track game audio and user interface sounds.

CSR's MusiCore1 technology presents handset makers with the first
practical audio processor architecture for phone designs, saving 75
percent of the cost, and over 36 mm2 of PCB space, of adding a separate
audio processor. Handset makers using CSR's MusiCore1 can, for the first
time, have stereo audio along with fully featured Bluetooth on a single
chip.

QSound's mQSynth is a wavetable MIDI synthesizer that supports polyphonic
ringtone files, game music and interactive real-time sound events using
digital wavetable instruments. mQSynth will also support formats
including SMF, SP-MIDI, SMAF, mXMF and JSR135.

MusiCore1 can support decoding of all mainstream music file formats
including MP3, AAC, WMA and SBC. The efficiency of CSR's mature DSP
architecture contributes to MusiCore1's ability to provide a phone with
100 hours of music playback. In addition, MusiCore1 enables sophisticated
voice processing in handsets, allowing users to comfortably make calls in
noisy environments.

"QSound's mQSynth engine provides a capability that is directly in line
with our own product strategy in delivering the most powerful and
complete audio solution for mobile handsets", commented Felicity
Skingley, Product Manager, Mobile Handset Connectivity Business Unit CSR

David Gallagher, QSound CEO commented, "CSR's selection of mQSynth as an
embedded MIDI synthesizer for MusiCore provides testament to the best in
class performance and efficiency of QSound's technology. It has been
gratifying to work with the established industry leader in the Bluetooth
market." Mr. Gallagher added, "The additional availability of QSound's
mQFX, our 3D stereo enhancement solution for multimedia on the MusiCore1
platform provides an attractive, compelling technology and licensing
proposition for all leading mobile OEMs."

Conscious of the limited space of mobile devices, CSR designed MusiCore1
to be even smaller than most Bluetooth chips. Samples of the very compact
3.8 x 4.8 mm CSP or BGA packages are available now and volume production
is scheduled to start in September 2008.
