Silence compression provides a way to squeeze redundancy out of sound files. The silence compression scheme is essential for efficient voice communication systems. It allows significant reduction of transmission bandwidth during a period of silence. A silence compression scheme include a voice activity detection (VAD), a silence insertion descriptor (SID) and a comfort noise generator (CNG) module. ==Parameters used for silence compression== *Threshold value *The way to encode silence *Threshold for recognizing start of silence *An indication of when silence is over *A parameter to get a threshold, which means that there is no silence until or unless there is three silence in the rows. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Silence compression」の詳細全文を読む スポンサード リンク
