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 indicative of the reduced audio signals, said method comprising the steps of:

  • converting the first signals to audio data of integers for providing second signals indicative of the audio data; and

    reducing inter-channel signal redundancy in the second signals for providing third signals indicative of the reduced second signals.
