ABSTRACT:
A five-channel perceptual audio compression system which encodes five matrixed channels switches among a fourteen encoding modes each utilizing a respective different set of matrixed channels. Six of the modes are for encoding the three front channels and eight of the modes are for encoding the two back channels. The rate of perceptual encoding the matrixed channels is controlled by adjusting individual noise thresholds as a function of a global masking threshold.
