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.727 is a specialized version of the ITU-T G.726 protocol
that is intended for packet-based systems using the Packetized Voice
Protocol (PVP). G.727 uses 5, 4, 3 and 2-bit/sample embedded
Adaptive
Differential Pulse Code Modulation (ADPCM). (See
also ADPCM).
See G.7xx for more information on how these standards are used in telephony
networks.
