Abstract
(EN)
In one embodiment, at least one channel in a frame of the audio signal is subdivided into a plurality of blocks such that at least two of the blocks having different lengths. A length of the frame is a user defined value and is determined within a predetermined value. Furthermore, information indicating the subdivision of the channel into the blocks is generated.
