Definitions for "G.729"
Keywords:  acelp, conjugate, algebraic, itu, codec
Part of the ITU-T's H.323 standard for videoconferencing over non quality-of-service guaranteed LANs.
ITU-T recommendation about an 8-Kbps speech coder using the CS-ACELP or, conjugate-structure algebraic-code-excited linear prediction speech coder. Annexes provide algorithms at 6.4- and 11.8-Kbps, C code and test verification suites.
Describes CELP compression where voice is coded into 8 kbps streams. The two variations of this standard G.729 and G.729 annex A , differ mainly in computational complexity; both provide speech quality similar to 32 kbps ADPCM.
