I actually think ANY decent MP3 encoder and decoder will do well at 192kbps (it wouldn't be "decent"
in my book if it couldn't). Where you hear real differences are at low bitrates. Since I do enjoy
several spoken-word podcasts, I can say that some organizations, for instance PBS and NPR, have
figured out how to get quite satisfactory audio quality (good clarity and few if any digi-swishies)
at even 32kbps. On the other hand, les technically savvy podcasters -- for instance Fox News -- do
things like encode 32kbps MP3 in stereo, even though it's spoken word that no purpose is served by
stereo. This insures digi-swishies galore and poor audibility. For music, where frequency response
and stereo are important, I have found that MP3 simply does not produce the best results for a given
bitrate or file size. For streams, Windows Media can do fantastic at 128kbps stream -- check out
Riverwalk Jazz for proof. RealMedia seems to be tricky to master but I've heard some very good
sounding streams from the BBC's vast website. Apple's version of MP4 seems to produce smaller file
sizes and higher audio quality than MP3 at a given bitrate.
Mike, I'm glad you've had good luck with LAME but I have found it to be very accurately named!

PS -- in case you haven't discovered it, I love the MP3 tagging utility Tag&Rename. Super-useful and
full of features you'd never think you need until you use them.
