A proprietary signal processing technology developed for the consumer
electronics and multi-media markets, the 3D Stereo integrated circuit is based on
technology derived from Desper Products multi-channel PRO 3D Audio Production
System.
The AN7399 makes use of this innovative technology to enhance and expand
existing stereo program material delivered by conventional 2 speaker stereo system.
