QS7779CM/QS7779PM
QSurround Matrix Surround Decoder/Virtualizer
Device Specifications - Preliminary Information
Overview:
The QS7779 is an audio processor IC which implements a decoder for a stereo matrix encoded source material such as
Dolby Surround, along with surround virtualization using QSurround
TM
technology developed by QSound Labs, Inc.
This chip also produces an enhanced stereo sound field for a stereo input signal. If the input signal contains matrix
encoded surround sound, the chip automatically decodes it and produces virtualized surround sounds for two-speaker
playback.
Feature:
Dolby Surround decoder capability
Virtualized surround sound with two speakers
Stereo sound enhancement
Center channel output option
Two enhancement levels
Parallel and serial digital interface for mode control
