Cue converter
 

I've heard good things about this one. ACDIR

Split cue
 

This might also help. Split lossless audio (ape, flac, wv, wav) by cue file in Ubuntu « aidanjm’s stuff

dbpower is great and works well even without a cue file dBpoweramp Music Converter

I convert flac files with my foobar media player. I believe flac to ogg (f.ex) functionality comes with the install (check options when installing), but if you need mp3s, you may need to download an mp3 encoder, f.ex lame mp3 encoder, which you then point foobar to when prompted.

As for splitting up flacs from a cue file, I just use medieval cue splitter. It's free, simple to use and does the job well.

Thanks Tore, I'll check it out!

i use something called "Audio Converter" from DVDVideoSoft

haven't tried converting CUE files
