Definition - What does G.728 mean?

G.728 is an International Telecommunications Union for Telecommunications (ITU-T) standard for audio compression and decompression. G.728 is a speech coding standard, which uses low delay code excited linear prediction operating at 16 Kbps at sampling rate of 8000 samples per second. It is used in digital transmission systems and is used for coding of analog into digital signals.

Techopedia explains G.728

G.728 pass low bit rate modem signals up to 2400 bps. Codec complexity is 30 million instructions per second (MIPS). Algorithmic coding delay of G.728 is 0.625 ms and is used for applications requiring 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 voice age G.728 implementation is compliant with the ITU-T G.728 recommendation.
