Claim Text:
1. A method for determining an encoding parameter for an audio channel signal of a plurality of audio channel signals of a multi-channel audio signal, each audio channel signal having audio channel signal values, the method comprising: determining for the audio channel signal a set of functions from the audio channel signal values of the audio channel signal and reference audio signal values of a reference audio signal, wherein the reference audio signal is another audio channel signal of the plurality of audio channel signals or a down-mix audio signal derived from at least two audio channel signals of the multi-channel audio signal; determining a first set of encoding parameters based on a smoothing of the set of functions with respect to a frame sequence of the multi-channel audio signal, the smoothing being based on a first smoothing coefficient; determining a second set of encoding parameters based on a smoothing of the set of functions with respect to the frame sequence of the multi-channel audio signal, the smoothing being based on a second smoothing coefficient; and determining the encoding parameter based on a quality criterion with respect to at least one of the first set of encoding parameters and the second set of encoding parameters.
