Audio Codecs G711-Alaw  and G711-Ulaw

Resolution

Audio Configuration:

  • G.711-Ulaw:

    Ulaw, or as it should be written: µ-law, is used in Japan and Northern America. This codec encodes 14-bit linear PCM audio samples into 8-bit logarithmic samples.

  • G.711-Alaw:

    This is the European version of ulaw and it is very similar except that it uses 13 bit linear PCM into 8-bit as above. This version is designed to be lighter on computer processing power than the ulaw version. Sound quality and bitrate is similar. Both versions of G.711 are waveform speech encoders.
