QSound Launches QDVD Plug-in For InterVideo's WinDVD



CALGARY, CANADA - February 5, 2003: QSound Labs, Inc. (NASDAQ: QSND), a leading supplier of audio software solutions, and InterVideo, Inc., a leading provider of software for movies, music and DVDs, today announced the immediate availability of the QDVD plug-in for InterVideo’s popular DVD player, WinDVD. QDVD is available for download from both QSound’s and InterVideo’s web sites for $14.95 US.

QDVD is based on QSound's High Definition audio library (QHD™). At the heart of QHD is QSound’s best-selling audio expansion technology, QXpander®, which takes the existing mono or stereo sound information and applies 3D processing proportionately to it, resulting in two-channel stereo output with a dramatically wider perceived sound field. QHD uses QSound's QRumble™ and QSizzle™ to restore both punch and brilliance to music, bringing the “warmth” of analogue playback to digital audio files. QDVD also features QSound’s newly developed “Dialog Enhancer”, which allows users to improve the dialog intelligibility independent of the remaining soundtrack, addressing the problem of muffled or masked dialog due to competing audio effects.

"WinDVD is the perfect showcase for QHD technology,” said David Gallagher, President and CEO, QSound Labs. “The combination of InterVideo’s leading video technology and QSound’s superior audio processing makes for an extremely compelling user experience."

InterVideo's WinDVD is a software-only DVD player for personal computers, that allows users to playback DVD movies, interactive DVD titles, MPEG audio and video, and audio CDs without the need for an expensive hardware decoder card. WinDVD has received praise from many leading trade magazines in the PC and DVD industry for its "remarkably pure DVD audio and video" and "impressive playback" capabilities.

"InterVideo is committed to providing the absolute best audio and video DVD experience for our users,” said Steve Ro, CEO of InterVideo. “QSound’s QDVD is a superb add-on for DVD movie fans who want clear, rich audio. The QDVD plug-in is a perfect addition for WinDVD users and works great whether you have WinDVD 3, WinDVD 4 or WinDVD Platinum."
