Claim Text:
1. Apparatus for processing an audio signal, comprising: an analysis filterbank for generating subband signals of the audio signal; a time manipulator for individually time manipulating a plurality of subband signals representing the audio signal, the time manipulator comprising: an overlap-add stage for overlapping and adding blocks of at least one of the plurality of subband signals using an overlap-add-advance value different from a block-extraction-advance value used for extracting the blocks from a subband signal of the plurality of subband signals; a transient detector for detecting a transient in the audio signal or the at least one subband signal of the plurality of subband signals, wherein the overlap-add stage is configured for reducing an influence of a detected transient or for not using the detected transients in a subband-individual manner when adding by the overlap-add stage; and a transient adder for adding a detected transient to the at least one subband signal generated by the overlap/add stage in a subband-individual manner.
