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 server. 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.
