G.726 vocoder is an ITU-T Adaptive Differential Pulse Code Modulation (ADPCM) standard speech codec. Adaptive Digital's G.726 speech coder is used in many applications that require high quality, robust speech reproduction. G.726 provides rates of 16, 24, 32, or 40 kbps. Applications include video conferencing systems, multimedia, flight recording, ISDN, and satellite communications.
The Adaptive Digital G.726 voice coder software is an implementation of the ITU G.726 voice coder. Adaptive Digital licenses two versions of it's G.726 speech software: a low memory version and a low MIPS version. The two versions produce the same results.
Coding Rate: 16, 24, 32, and 40kbps
Sampling Rate: 8 kHz
Delay: 125 usec
