Mountain View, CA. Desper Products, Inc., the audio products division of Spatializer Audio Laboratories, Inc. today announced Digital Virtual Surround-5.1™ (DVS-5.1). This is a technology that enables Dolby Digital Surround (AC-3) playback from two conventional speakers or headphones, instead of the 5+ speakers normally required.
DVS-5.1 is the second such technology introduced this month. Two weeks ago, Aureal Semiconductor Inc. announced Aureal 3D™ (A3D), which will use proprietary Aureal chips to get the job done. Desper’s technology is currently running on the Motorola 56009 AC-3 decoder, and is available for licensing on numerous DSP platforms.
“With the advent of high-density data media such as DVD, DSS and HDTV, consumers will find more software titles, music and videos are encoded in the AC-3 format,” said Steven D. Gershick, President and CEO of Spatializer. “However, not everyone can justify having six speakers to enjoy true multi-channel playback. With DVS-5.1, we offer an easily implemented, cost-effective, high-fidelity two-speaker solution for AC-3 multi-channel audio playback.”
The name DVS-5.1 refers to the speaker configuration of Dolby AC-3: 5 main speaker channels at left, center and right front, left and right surround; plus a low frequency channel (the “.1”) directed to a subwoofer if available. In DVS-5.1, the surround, center-front and low frequency channels are eliminated and their corresponding signals are processed by DVS- 5.1 to simulate the effect of loudspeakers placed at those locations.
