Is it just as bad, then? For some sounds, the ISO demo code and most programs derived from it (s.a. 8hz-mp3, no longer available, bladeenc, possibly gogo as well - I don't know) produces results that are unacceptably weird. I would assume that my experiences are due to the bugs in the psychoacoustic model referred to in the LAME documentation. In many of these cases, LAME produces better output. I've yet to find any cases where LAME would be worse, although I can sometimes hear audible degradation compared to CD-quality. Note that I almost always listen to music using headphones. You can't necessarily hear the differences in mp3 quality at 128kbit/s using typical stereos (or even worse, "computer speakers") over the noise of your computer.
