Is there a free MP3 encoder that works under Windows NT?
CDEX, available from: www.cdex.n3.net will convert WAV files to MP3 using either the Blade or the LAME encoder (both included). It does not require any special install – you simply unzip the programs into a directory. It supposedly runs fine under NT, although I haven’t tried it on an NT machine, only in Win 95 and Win 98 (its documentation specifically says that it works under NT, though).
