Apparatus and method for processing an audio signal using a combination in an overlap range

摘要

An apparatus for processing an audio signal comprising a sequence of blocks (114) of spectral values comprises: a processor (100) for processing the sequence of blocks using at least one modification values (102) for a first block to obtain aliasing-reduced or aliasing-free first result signal in an overlap range (170) and using at least one second different modification value (106) for a second block of the sequence of blocks to obtain an aliasing-reduced or aliasing-free second result signal (108) in the overlap range (170); and a combiner (110) for combining the first result signal (104) and the second result signal (108) in the overlap range (170) to obtain a processed signal (112) for the overlap range (170).
