Abstract:
1. A method of coding at least part of an audio signal with an audio encoder in order to obtain an encoded signal, the method comprising: predictive coding the at least part of the audio signal in the audio coder in order to obtain prediction coefficients which represent temporal properties of the at least part of the audio signal; transforming the prediction coefficients into a set of times representing the prediction coefficients; and including the set of times in the encoded signal, wherein: the at least part of an audio signal is segmented in at least a first frame and a second frame the first frame and the second frame have an overlap including at least one time of each frame, and for a pair of times consisting of one time of the first frame in the overlap and one time of the second frame in the overlap, a derived time is included in the encoded signal, which derived time is a weighted average of the one time of the first frame and the one time of the second frame.
