[ID3 Dev] what is the different between Riff Mp3 & Mp3 file format?

[Mark Smith]

Not necessarily.

The WAV format is a sub-set of the RIFF format, and may contain audio  
in many formats. Most commonly that will be uncompressed PCM audio,  
but could be mp3 compressed audio.

The 'fmt' sub-chunk in the WAV header indicates the format of the  
audio in the file.
