16/24/32/40 0.250 0.375 ADPCM
G.726 is an implementation of ITU-T G.726 standard for conversion linear or A-law or ยต-law PCM to and from a 40, 32, 24 or 16 kbit/s channel. The specification uses Adaptive Differential Pulse Code Modulation (ADPCM) technique which is applicable to all waveforms, high-quality audio, modem data etc.
ITU-T recommendation for ADPCM (adaptive differential pulse code modulation) coding at 16-, 24-, 32- and 40-Kbps. Includes useful annexes.
Describes ADPCM coding at 40, 32, 24 and 16 kbps. ADPCM encoded voice can be interchanged between packet voice, PSTN, and PBX networks if the PBX networks are configured to support ADPCM. Described in the ITU-T standard in its G-series recommendations.

This vocoder, commonly called ADPCM (Adaptive Differential Pulse Code Modulation), is used in the NACT IPAX gateway for the playback of voice messages such as authorization code and destination number prompts. This vocoder algorithm can produce bit rates of 16, 24, 32, and 40 Kbits/second. The NACT IPAX voice prompts are recorded at 32 Kbits/second. This vocoder has no silence suppression, meaning silence is transmitted and occupies bandwidth.
40/32/24/16 ADPCM codec (good quality, medium bandwidth, low processor load)
An ITU-T ADPCM wave form codec (16/24/32/40 kbps, good quality, low processor load).
an international standard for encoding 8 kHz sampled audio signals for transmission over 16, 24, 32 and 40 kbps channels. The G.726 standard specifies an adaptive differential pulse code modulation (ADPCM) system for coding and decoding samples.
An ITU-T audio coding and decoding recommendation that defines the characteristics for conversion of a 64 Kbps A-law or _-law PCM channel at 8000 samples per second to and from a 40, 32, 24, or 16 Kbps channel. The conversion is applied to the PCM stream using an adaptive differential pulse code modulation (ADPCM) transcoding technique. G.726 is useful for applications that require speech compression, encoding for noise immunity, and uniformity in transmitting voice and data signals.
Used for computer telephony. Good for keeping of human speech.
G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate.
