G.729

G.729 is a royalty-free narrow-band vocoder-based audio data compression algorithm using a frame length of 6.3 ms. It is officially described as Coding of speech at 8 kbit/s using code-excited linear prediction speech coding (CS-ACELP), and was introduced in 1996. The wide-band extension of G.729 is called G.729.1, which equals G.729 Annex J.
