Apparatus, method and computer program for manipulating an audio signal comprising a transient event

摘要

An apparatus (100) for manipulating an audio signal (110) comprising a transient event comprises a transient signal replacer (130) configured to replace a transient signal portion, comprising the transient event of the audio signal, with a replacement signal portion adapted to signal energy characteristics of one or more non transient signal portions of the audio signal, or to signal energy characteristics of the transient signal port! to obtain a transient - reduced audio signal (132). The apparatus also comprises a signal processor (140) configured to process the transient -reduced audio signal (132) to obtain a processed version (142) of the transient -reduced audio signal (132). The apparatus also comprises a transient-signal-re-inserter (150) configured to combine the processed version of the transient-reduced audio signal (132) with a transient signal (152) representing, in an original or processed form, a transient content of the transient signal portion.
