I like LAME.
A co-worker went through and hit MP3 encoders with a bunch of
complex-overtone signals in an attempt to provoke audible artifacts. He
concluded that LAME did seem to be doing the best job of preserving
details of these deliberately difficult waveforms, for equivalent
compression rates.
Haven't yet gotten around to trying LAME myself. I really should, I s'pose.
I'll agree, at least for higher bitrates. I prefer Fraunhofer for low
bitrate (<64k) voice.
