Abstract:
1. A method of coding audio signals in a sound system having a plurality of sound channels for providing M sets of audio signals from input signals, wherein M is a positive integer greater than 2, and wherein a plurality of intra-channel signal redundancy removal devices are used to reduce the audio signals for providing first signals in the plurality of sound channels indicative of the reduced audio signals, said method comprising the steps of: converting the first signals in at least two of the plurality of sound channels to audio data for providing second signals in said at least two sound channels indicative of the audio data; quantizing the second signals according to a masking threshold for providing a further second signals; and operatively engaging the further second signals in said at least two sound channels, separately from the intra-channel signal redundancy removal devices, for reducing inter-channel signal redundancy in the further second signals in order to provide third signals indicative of the reduced further second signals in said at least two sound channels.
