What is G.728?
G.728 is an international ITU-T standard for audio compression and decompression. G.728 is a speech coding standard that uses linear code delayed code excitation linear prediction operating at 16 Kbps at a sampling rate of 8,000 samples per second. It is used in digital transmission systems and is used to encode analog into digital signals.
G.728 transmits modem signals with a low bit rate of up to 2400 bps. The codec complexity is 30 million instructions per second (MIPS). The algorithmic coding delay of G.728 is 0.625 ms and is used for applications that require a low algorithmic delay. It is an optional codec for compliance with the H.320 standard for audio or video telephony on switched digital circuits. The implementation of the language age G.728 corresponds to the ITU-T G.728 recommendation.
