G.728 Last modified: Wednesday, May 07, 2008
An International Telecommunications Union (ITU-T) standard for for audio (speech) compression and decompression that is used in digital transmission systems, and in particular, used for the coding of analog signals into digital signals. G.728 is an ITU-T speech coding  standard that uses Low Delay Code Excited Linear Prediction (LD-CELP) operating at 16 kbit/s compression at a sampling rate of 8,000 samples per second. The algorithmic coding delay of G.728 is 0.625 ms. G.728, when compared to G.726 delivers close to the same voice quality but uses only one-half the bandwidth. See G.7xx for more information on how these standards are used in telephony networks. See also LD-CELP.
