Description
Echo Canceller was designed and used to address and standardize the
performance of echo cancellers in the PSTN.
Highest Bandwidth/Lowest Compression - best voice quality. A voice
encoder that compresses 64K bit stream to an 8K per second sampling
rate, with a typical algorithmic delay of 0.125ms. G.711 is used when
transmitting Music, FAX'es and DTMF tones because it is very reliable.
Intermediate Bandwidth/Intermediate Compression - minimal reduction in
voice quality. A voice encoder that compresses voice in 30ms frames, with
a look-ahead of 7.5ms, with a typical algorithmic delay of 37.5ms. G.729a
uses very low bandwidth because it samples at 8kHz/16-bit (240 Samples
for 30ms frames).
Lowest Bandwidth/Highest Compression and least complex protocol, with a
hybrid speech reproduction quality by use of an Algebraic Code Excited
Linear Predication (ACELP) that reproduces a voice encoder that
compresses voice in 10ms frames, with a look ahead of 5ms per frame, and
atypical algorithmic delay of 15ms, per frame. It operates at 8k bits, and
can be used with 6.4kbits and 11.8k bits, with a marginal reduction in voice
quality.
