Title:
オーディオ信号の編集
Document Type and Number:
Japanese Patent JP2004538502
Kind Code:
A
Abstract:
A method of editing (4) relatively long frames with high sub-frame accuracy for editing in the context of sinusoidal coding is disclosed. In order to provide such a method for high accuracy editing, so called transient positions can be applied where an edit point (EEP, SEP) is desired in a previously encoded signal (AS). The adding is done as some kind of post-processing, by for example an audio editing application. The advantage of using a transient position as an edit point, is that the signal can then abruptly end or start at the transient position, in principle with sample resolution accuracy, whereas in prior art systems, one is limited to frame boundaries, which occur, for example, once per 100 ms.
