method for decoding m encoded audio channels representing n audio channels and method for encoding n input audio channels into m encoded audio channels.

摘要

multi-channel audio encoding. The present invention relates to multiple audio channels that are combined in either a monophonic composite signal or multiple audio channels together with the relative auxiliary information from which multiple audio channels are reconstructed, including a multi-channel reduction mix. audio to a monaural audio signal or to multiple audio channels, and an enhanced correlation of multiple audio channels derived from a monaural audio channel or multiple audio channels. Aspects of the described invention are usable in audio encoders, decoders, encoding / decoding systems, reduction mixers, expansion mixers, and correlators.
