VOICE-TO-REMAINING AUDIO (VRA) INTERACTIVE CENTER CHANNEL DOWNMIX.

摘要

A method for decoding an audio signal includes receiving a digital audio signal having a plurality of channels (221-226 or CENTER, ALL OTHER SPEAKERS) defined thereon, wherein one of the plurality of channels is a center channel (C or CENTER) and at least one of the other of the plurality of channels is a remaining audio channel; comparing the center channel (C or CENTER) with the at least one of the other of the plurality of channels (221-224 or ALL OTHER SPEAKERS); and automatically adjusting (232, 233) the center channel and the at least one of the plurality of other channels when a predetermined value for the ratio is not met.
