The input and output contain 16-bit pulse-code modulation (PCM) samples converted from or to 8-Kbps compressed data. The total algorithmic delay is 15 ms. In G.729AB, the parameters are the same as in G.729A with the addition of voice activation detection (VAD) in which the effective signal bandwidth is reduced when there is no audio input. A technology known as comfort noise generation (CNG) produces a small amount of background pink noise during pauses … Voice Communications Software definition sponsored by SearchUnifiedCommunications.com, powered by WhatIs.com an online computer dictionary
