GSM a AU file

[Robert Vojta]

  Jenom pro upřesnění ... Je to pro Cisco, který používá své vlastní
rozšíření .au formátu:

The gateway uses standard codec numbers for the codec format in the
audio header whenever possible, including G.711 u-law, G.711 a-law,
and G.726 (32k ADPCM); other codecs use a proprietary format mapping
and may therefore not be recognized by third-party audio players. For
a listing of the codec numbers used by the Cisco gateway, see the
"Codec Mappings in Audio Recordings" section.

  Daná čísla jsou k nalezení zde:
