.G721 - Raw CCITT/ITU G.721 4-bit (32 kbps) ADPCM format data

Notes:

• There's no standard file extension for this type of data and there's no way to auto-detect the format, so you'll have to use a .G721 file extension to make the program recognize what it is!
  
  

Features:

• ADPCM 4-bit lossy compression, mono.

Supported by:

• Awave Studio (read + write).
