Split MonkeyAudio (.ape + .cue + .log) of whole audio CD into MP3 of individual tracks

You can use CUETools, to do it — load up the .cue file or .ape file with the other one in the same directory, select tracks for cue style and mp3 output and it'll automate the whole process.

I use CUE Splitter, works like a charm, Windows only.

On Linux, you could use mac to dump the .ape into .wav, then bchunk to split the big .wav file into tracks using information from the .cue file.

.wav to .mp3 can be done with lame/ffmpeg.

I'm pretty sure there must be shellscripts that automate the whole process (including the population of ID3 tags), but finding them is a trivial google task, since now you know a lot of keywords.

As you could see, I assumed Linux, if you want to do it using another operating systems, consider to add the os name as tag, to get more precise answers.
