mp3guessenc is based upon the original project by Naoki Shibata. This command line utility was born to detect the encoder used for a mpeg layer III file but now it can do more and scan any mpeg audio file (any layer) and print a LOT of useful information. Latest modifications include fixes, new features and code optimizations.
