摘要: The invention relates to a method for supporting an encoding of audio signal, wherein at least first and second coder mode are available section the signal. enables coding based on two different models. A selection model is enabled by rule which signal characteristics have been determined certain analysis window. In order avoid misclassification after switch mode, it proposed that activated only when sufficient sections window received. equally module 2,3 in this implemented, device 1 system comprising such 2,3, software program product including code realizing method.
