There is a shell script that can convert a big APE/FLAC file to mp3 files easily. The author of the script is not clear, the script just says: Brian’s Archive CUE/FLAC Splitter v0.1, No sanity checking in place. Be careful.
Download the script ‘ape2mp3′. The original script has been slightly modified to be used with newer versions of the related software.
Use of the script is very simple (of course you need both the CUE file and the APE/FLAC file):
# ape2mp3 album.cue album.ape
