SOUND PROCESSING SYSTEM WITH DEGRADED SIGNAL OPTIMIZATION

摘要

A sound processing system adaptively mixes active matrix decoding and passive matrix processing of incoming audio signals. Mixed outp ut signals are generated with active matrix decoding where the audio signals ar e stereo. Mixed output signals are generated with passive matrix processing where the audio signals are monaural. The sound processing system reduces the degree of acti ve matrix decoding in the mixed output signals where the incoming audio signals are stereo and monaural. The sound processing system also generates virtual ster eo signals from incoming audio signals having monaural signals. Mixed output signals are generated of the virtual stereo signals using active matrix decoding.
