G.722
G.722 is a ITU-T standard wideband speech codec operating at 32-64 kbit/s. Technology of the codec is based on split band ADPCM. G.722.1 offers lower bit-rate compressions. A more recent variant, G.722.2, also known as "Adaptive Multirate Wideband" (AMR-WB) offers even lower bit-rate compressions,..
G.722.1
G.722.1 is an ITU-T standard audio codec meant for low bit rate audio coding below 64 kbit/s. It is based on Polycom's SIREN codec. See also G.711 (a-law and mu-law/u-law)G.722G.722.1G.723G.723.1G.726G.728G.729G.729aList of codecs ..
G.723
This article or section is in need of attention from an expert on the subject.Please help recruit one, or improve this page yourself}} if you can. See [discussion page] for details. G.723 is a ITU-T standard wideband speech codec. This is an extension of Recommendation G.721 adaptive dif..
G.723.1
G.723.1 is an audio codec for voice that compresses voice audio in chunks of 30 milliseconds. A look-ahead of 7.5 ms duration is also used. Music or tones such as DTMF or fax tones cannot be transported reliably with this CODEC, and thus some other method such as G.711 or out-of-band methods should ..
G.726
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 ADCPM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16&..
G.728
G.728 is a ITU-T standard for speech coding operating at 16 kbit/s. Techology used is LD-CELP, Low Delay Code Excited Linear Prediction. Delay of the codec is only 5 samples (0.625 ms). The linear prediction is calculated backwards with a 50th order LPC filter. The excitation is generated ..
G.729
G.729 is an audio data compression algorithm for voice that compresses voice audio in chunks of 10 milliseconds. Music or tones such as DTMF or fax tones cannot be transported reliably with this codec, and thus use G.711 or out-of-band methods to transport these signals. G.729 is mostly used in Voi..
G.729a
G.729a is an audio data compression algorithm for voice that compresses voice audio in chunks of 10 milliseconds. G.729a is compatible with G.729, but requires less computation. This lower complexity is not free since speech quality is marginally worsened. The CODEC was developed by a consortium ..
