The g721 file extension is associated with the Raw CCITT/ITU G.721 4-bit ADPCM sound format.
An ITU standard for speech codecs that uses the ADPCM method and provides toll quality audio at 32 Kbps. ADPCM 4-bit lossy compression, mono.
There's no standard file extension for this type of data and there's no way to auto-detect the format, so use a *.g721 file extension to make the Awave Studio recognize what it is!
Probably can be exported to other formats.
