Edit / An ITU standard PCM codec that converts analog speech to or from a stream of digital data. G.729A employs data compression techniques so that a voice conversation that would normally take 64Kbps of bandwidth (using G.711 can be transmitted using only 8Kbps. Requiring a lower data-rate allows G.729A to utilize available bandwidth more efficiently but also makes the call much more fragile in the face of network transmission impairments such as packet loss. It also reduces the legibility, especially in situations where the signal is re-digitized multiple times (such as when a digital cordless phone is used). See Also: PLC
The International Telecommunications Union's (ITU) standard voice algorithm for the coding and decoding of speech at 8 kilobits per second.
Describes CELP compression where voice is coded into eight-kbps streams. There are two variations of this standard (G.729 and G.729 Annex A) that differ mainly in computational complexity; both provide speech quality similar to 32-kbps ADPCM. Described in the ITU-T standard in its G-series recommendations.
