Mp3stat is Linux a utility program to compare encoders against an MP3 that was VBR encoded. It outputs a linear graphical bitstream analysis of each MP3 being compared and gives you a breakdown of how many frames of each bitrate are found in the MP3. It basically allows you to see how encoders treat areas in the same MP3s differently and lets users discover some of the bitrate effects of different quality levels of the same encoder. Mp3stat also supports Oggs.

Version 2.5.10 of mp3stat is shipping as July 2004.
