What is G729 codec:
G.729 is a royalty-free narrow-band vocoder-based audio data compression algorithm using a frame length of 10 milliseconds. It is officially described as Coding of speech at 8 kbit/s using code-excited linear prediction speech coding and was introduced in 1996. The wide-band extension of G.729 is called G.729.1, which equals G.729 Annex J.
Purpose of G729 codec:
Because of its low bandwidth requirements, G.729 is mostly used in voice over Internet Protocol (VoIP) applications when bandwidth must be conserved. Standard G.729 operates at a bit rate of 8 kbit/s, but extensions provide rates of 6.4 kbit/s and 11.8 kbit/sfor worse and better speech quality, respectively.
