Hello,
I have not followed completely this thread, but i wonder if the question
should be "what is the best MP3 decoder" instead of "encoder".
I almost always used lame (or liblame) as an encoder, but with the same
mp3 file encoded by lame, i could actually _hear_ a diffenrence among
several mp3 decoders. AFAIR, in the early 2k years, mpg123 was far
better than mpg321, if i remember well. I hope my memory doesn't fail..
cheers,
- Ben
