Summary

Recommendation ITU-T G.711.0 describes a lossless compression scheme of a G.711 bitstream, mainly aimed for transmission over IP (e.g., VoIP).

The coder operates on frame lengths of 40, 80, 160, 240 and 320 samples, has a maximum algorithmic delay equal to the frame length, and has a worst-case computational complexity of less than 1.7 weighted million operations per second (WMOPS) for encoder plus decoder.

This Recommendation includes an electronic attachment containing a non-exhaustive set of test signals for use with the ANSI C code. ANSI C source code is provided for the fixed-point arithmetic implementation of the specification.
