For changing a segmentation of an audio piece after a segment class
assignment, at first a short segment is selected, which has a length
shorter than a predetermined minimum length. This short segment is
preferably merged with the corresponding successor segment or predecessor
segment using information on a segment class membership of the short
segment itself, but also the successor segment or the predecessor
segment, in order to obtain a changed segmentation of the audio signal.
With this, a not over-segmented segment representation of the audio
signal is obtained, which further includes all audio information, i.e. is
not a representation of the audio piece with holes.
