CUE Splitting

This article describes how to split audio files using CUE metadata.

Installation

To split audio files you need shntool.

To split iso or bin files you need bchunk.

To read some audio files you may need an appropriate decoder. For example: flac or wavpack.

To encode files to any format other than wav you need to install encoders. For example: flac, lame, or vorbis-tools.

To tag audio files you need extra tools such as: cuetools, mp3info, or vorbis-tools.

Splitting

To split a disc audio file accompanied by a cue sheet use the shnsplit command:

 shnsplit -f file.cue file.ape

To split bin files with cue sheets use:

 bchunk -v -w file.bin file.cue out

All these commands produce .wav files. You probably want to compress the audio files with formats like flac or mp3.

shnsplits gives the possibility to convert on the fly to most lossless formats, like flac. It can be used like so:

 shnsplit -f file.cue -o flac file.ape

If you need more control over the conversion you may change the converter parameters inline:

 shnsplit -f file.cue -o "flac flac -s -8 -o %f -" file.ape

Even better, automatically name split files with track number and title:

 shnsplit -f file.cue -t "%n %t" -o "flac flac -s -8 -o %f -" file.ape

The formats shnsplit supports can be view using the command

 shntool -a

It doesn't really matter, though, if shnsplit doesn't support a format you want to use. Just specify any format you want, then override the correct file extension and command it would normally use with your own. For example, at the time this was written, shnsplit doesn't support vorbis, but this command works just fine:

 shnsplit -f file.cue -t "%n %t" -o "flac ext=ogg oggenc -b 192 -o %f -" file.ape

Tagging

You'll need cuetools to use cuetag.sh.

To copy the metadata from a cue sheet to the splitted files you can use:

 cuetag.sh file.cue *.mp3

or if you need to select only certain files:

 cuetag.sh file.cue track01.mp3 track02.mp3 track03.mp3 track04.mp3

cuetag.sh supports id3 tags for .mp3 files and vorbis tags for .ogg and .flac files.

Alternatives

• This is a script that splits and converts files to tagged FLAC: https://bbs.archlinux.org/viewtopic.php?id=75774.
• You can also try the split2flac or split2flac-git script from the AUR.
• You may also use flacon or flacon-git , a graphical Qt program that splits, converts and tags album audio files into song audio files.
