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 …

G.711 and G.726 are both ITU-T standards for audio compression, but they differ in terms of their compression algorithms and bit rates. G.711 uses a pulse code modulation (PCM) algorithm and has a fixed bit rate of 64 kbps, making it ideal for high-quality voice communication.

* * The ITU-T G.726 coder is an adaptive differential pulse code modulation * (ADPCM) waveform coding algorithm, suitable for coding of digitized * telephone bandwidth (0.3-3.4 kHz) speech or audio signals sampled at 8 kHz. * This coder operates on a sample-by-sample basis.

The G.726 is a voice-compression algorithm standard defined by the International Telecommunication Union (ITU). It can be used in many applications such as digital cordeless telephones, radio/wireless local loop, and pair-gain.

Simplified block diagrams of both the ADPCM encoder and decoder are shown in Figure 1/G.726. In § 4, each sub-block in the encoder and decoder is precisely defined using one particular logical sequence.

G.726 is an ADPCM -based narrowband codec (50 to 4000 Hz) of the International Telecommunication Union (ITU-T) for compressing speech into digital telephone signals. The method is based on Adaptive Differential Pulse Code Modulation (ADPCM). The codec supports bit rates of 16, 24, 32 and 40 kbit/s.

G.726 and G.711 encoder and decoder developed by SPIRIT Corp. for TMS320C54xx platform and is intended for integration into devices for encod-ing and decoding differential pulse coded signals. ITU-T G.726 implements adaptive differential pulse code modulation (ADPCM) encoding and decoding of voice frequencies.
