Thanks. I thought I had in knocked with lame, but the recorder I'm
using, a java applet called nonogong from Hong Kong university, uses an
imaADPCM, 4-bit format for its .wav files that lame chokes on. ffmpeg
has no problem! But I cannot get ffmpeg to run on my ViaVerio FreeBSD

The nanogong applet can also use speex, but I don't know how to play
back speex. All this has to work in microsoft browsers because that's
what everyone who has a computer has her in Thailand. As elsewhere I
suppose, still.

HTML 5 is coming... but not yet. And to microsoft kicking and screaming.

If anyone knows of a way to convert 4bit imaADPCM .wav files to mp3 on a
FreeBSD machine I'd be very happy to hear of it!

Thanks for your help.
