Abstract:
1. An apparatus for changing a segmentation of an audio piece into temporal segments, wherein the audio piece is structured into main parts repeatedly occurring in the audio piece, comprising: a provider for providing a representation of the audio piece, in which the segments of the audio piece are assigned into various segment classes, wherein one segment class each is associated with a main part, wherein the provider is formed to provide a novelty value for segment boundaries of the short segment, wherein the novelty value indicates how much novelty content the short segment has with reference to a segment adjoining the segment boundary; and a segment corrector for correcting the segmentation, wherein the segment corrector is formed to merge a short segment with a length shorter than a predetermined minimum length with a temporal predecessor segment or a temporal successor segment to obtain a changed segmentation of the audio signal, and wherein the segment corrector is formed to merge the short segment with the segment adjoining the segment boundary of the short segment, which has a novelty value indicating a lower novelty content compared with a novelty value at another segment boundary of the short segment.
