Press Release Summary: CSR's MusiCore1 is the world's first fully featured
single-chip stereo audio processor with Bluetooth for mobile phones.

Press Release Body: Bangalore, 21st April 2008 - CSR (LSE: CSR) and QSound Labs Inc.
(NASDAQ: QSND) today announced that CSR's MusiCore1 is now being offered with
mQSynthT, a powerful wavetable MIDI synthesiser 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
36mm2 of 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 synthesiser 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 synthesiser 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 PCB space of mobile devices, CSR designed MusiCore1 to be
even smaller than most Bluetooth chips. Samples of the very compact 3.8x4.8mm CSP or
BGA packages are available now and volume production is scheduled to start in
September 2008.
