Device and method for manipulating an audio signal having a transient event

摘要

Abstract Apparatus for manipulating an audio signal having a transient event (801), comprising: a signal processor (110) for processing a transient reduced audio signal in which a first 5 time portion (804) comprising the transient event (801) is removed or, for processing an audio signal comprising the transient event (803) to obtain a processed audio signal; a signal inserter (120) for inserting a second time portion (809) into the processed audio signal at a signal location, where the first portion was removed or where the transient event is located in the processed audio signal, wherein the second time portion (809) 10 comprises a transient event (801) not influenced by the processing performed by the signal processor (110) so that a manipulated audio signal is obtained; and a side information extractor (106) for extracting and interpreting a side information associated with the audio signal, the side information indicating a time position (803) of the transient event or indicating a start time instant or a stop time instant of the first time 15 portion or the second time portion. 3488701_1 (GHMatters) Pa5079.AU.3 audio 101 signal transient 102 '-- _ with signal signal transient remover processor processed audio signal 122 123i 111 (with or without transient event) L------------------------signal inserter 120 transient 1 4 0 -- s ig n a l (and neighbor- 141 audio signal with hood) generator 121 unprocessed, "natural" or synthesized transient signal - 130 conditioner
