>Description:
new port: audio/mp3guessenc - Utility for guessing which encoder was used to encode an mp3 file

This is a program which analyzes an mp3 file and guesses which encoder was
used.

All encoders have some characteristics in encoded MP3 file. For example, Xing
encoder never uses short block. This program analyzes which features are used in
the given MP3 file and guesses which encoder is used to encode the MP3 file.

The guess is not always correct.
