ITU G.711
ITU-T recommendation G.711 is a standard for audio companding using pulse code modulation (PCM). It uses a 8kHz sampling rate. Two main compression algorithms are defined, μ-law and A-law. The μ-law algorithm is used in North America and Japan and tends to give more resolution to higher range signals. The A-law algorithm is used in Europe and the rest of the world and provides more quantization levels at lower signal levels.
The ESPICO implementations are highly optimised, realising low memory and MHz requirements. Contact ESPICO for specific resource requirements.
