Given a single lossless audio file (wav, flac, ape, wv, etc.) foo and corresponding cue sheet foo.cue, we can split it into separate tracks (compressed by flac) by the following command:

$ shnsplit -f foo.cue -o "flac flac --verify --best -o %f -" -t "%n-%p-%t" -m " _" foo

See shntool(1) for more options.

Note that the cue sheet file may require removing trailing spaces and converting to utf-8.

Split points in cue sheets are often specified in the form mm:ss:ff (minutes:seconds:frames). There are 75 frames per second, so ff ranges from 00 to 74. shnsplit accepts this format only for CD‐quality (i.e., 16/44.1) audio files. For other files (e.g., 24/192) the split points must be given in the form mm:ss:nnn (minutes:seconds:milliseconds). nnn is the integer part of (40/3)⋅ff

To split a Monkey's Audio (ape) file one should first convert it to wav:

$ mac foo.ape foo.wav -d
