RealAudio 28.8

• FOURCCs: 28_8
• Company: RealNetworks

RealNetworks' 28.8 kbits/sec codec. Actual data rate is 15.2 kbits/sec. Variant of ITU-T G.728.

RealAudio uses a reduced-bitrate variant of G.728. The original G.728 source code is available here. RealPlayer appears to be based on this implementation as the function names match those in the RealPlayer 5 beta. FFmpeg's decoder is based on a different implementation.
