Recording & playback of multi-channel digital audio having different resolutions for different channels

摘要

The method involves sampling a set of channels of audio data (12,14,16,18). Two of the set of channels are encoded at different data depths and encoding rates in a single stream in a track on a software carrier (10). Weighting information is provided for deriving two-channel stereo from the set of channels of audio data. An additional two-channel audio track is provided on the software carrier. Independent claims are also included for the following: (a) a method of recording and playing back a set of channels of recorded multi-channel digital audio signal samples provided on a software carrier (b) a device for playing back recorded multi-channel digital audio signal samples.
