here's the dope.. Fraunhoffer codec will make bad MP3's sound like crap, so be prepare to rerip, and redownload what you don't like..
I've had Fraunhoffer on my computer for a while, and with my Sennheiser headphones, you can tell the difference. however that codec eats my CPU quite a bit, which is why I've got the LAME plugin working instead, of the default nitrane, or fraunhoffer. however I don't really notice anything different from Nitrane, so I'll probably go back..
I've got to check out this alpha version of the next winamp decoder..
finally, all these audio plugins (wowthing etc) are just poor excuses for not setting the eq/having bad speakers.. I've tried em, and they're more a hassle then they are worth. I have my eq set on full bass and full treble (I don't like to hear the middle spectrum too much), however that gives me alot of distortion.
I know exactly why it gives me this distortion. the only way out of it is to turn my pre-amp wayy down. when I turn off the eq, for the most part, the distortion gets wiped out (on some songs, there still is).
