METHOD FOR DECODING M ENCODED AUDIO CHANELS REPRESENTING N AUDIO CHANNELS

摘要

The present invention discloses a method for decoding M encoded audio channels representing N audio channels, where N is two or more, and a set of one or more spatial parameters, wherein one or more of said spatial parameters are differentially encoded, the method comprising receiving said M encoded audio channels and said set of spatial parameters, applying a differential decoding process to the one or more differentially encoded spatial parameters, deriving N audio signals from said M encoded channels, wherein each audio signal is divided into a plurality of frequency bands, wherein each band comprises one or more spectral components, and generating a multichannel output signal from the N audio signals and the spatial parameters.
