Split flac by cue file in Debian / Ubuntu / Linux

Update: I found  split2flac,which does all this automatically.

From aidanjm’s stuff :

Lossless audio files can be split by cue file using “shnsplit” (part of the “shntool” package). You will also need the “cuebreakpoints” tool (part of the “cuetools” package) and “cuetag” to transfer the tags.

To install cuetools and shntool in Ubuntu/ Kubuntu, open a terminal window and enter the following:

sudo apt-get install cuetools shntool

You will also need software for your prefered lossless audio format. For FLAC you need to install “flac”.

Shnsplit requires a list of break-points with which to split an audio file. Conveniently, cuebreakpoints prints the break-points from a cue or toc file in a format that can be used by shnsplit. You can pipe the output of cuebreakpoints to shnsplit as follows:

cuebreakpoints sample.cue | shnsplit -o flac sample.flac

Or, without cuebreakpoints

shnsplit -f sample.cue -o flac -t “%n. %t” sample.flac < sample.cue

In this example, a flac file called “sample.flac” is split according to the break-points contained in “sample.cue” and the results are output in the flac format.

The output file format is specified via the “-o” option. If you don’t specify an output format your split files will be in shntool’s default format (i.e., wave files, “wav”).

To split a monkey’s audio file by cue file and output the results in the flac format:

cuebreakpoints sample.cue | shnsplit -o flac sample.ape

Note that a default prefix “split-track” is used to name the output files. (The default output format is split-track01, split-track02, split-track03, …). You can specify your own prefix via the “-a” option.

To see all the options for shntool split type “shntool split -h” or “shnsplit -h”.

Pay special attention to the -t fmt option to rename the split files:

shnsplit -f sample.cue -o flac -t “%n. %t” sample.flac < sample.cue

Transferring tags

The audio files output by shnsplit do not contain tag data. However you can use the “cuetag” script (installed as part of the cuetools package) to transfer tag data directly from a cue file to your split audio files. You specify the individual audio files corresponding to the tracks contained in your cue file as follows:

cuetag sample.cue split-track01.flac split-track02.flac split-track03.flac split-track04.flac

This will transfer the tag data contained in “sample.cue” to the flac audio tracks “split-track01.flac” “split-track02.flac” “split-track03.flac” and “split-track04.flac”.

The above command could be streamlined as:

cuetag sample.cue split-track*.flac or cuetag sample.cue *.*.flac

Cuetag works with flac, ogg and mp3 files. The cuetag script is not currently able to handle file names containing spaces.

Update: I found  split2flac,which does all this automatically.

  2. Try Flacon instead, native Ubuntu, has gui, found it in Software Center. Splits & converts FLAC/APE/CUE to various formats. Found it last night, works perfect :-D

    • … but that’s a much more complicated solution. Flacon is an audio converter. I think if you want to just split the files, a more simple approach like split2flac is preferable.
      And native Ubuntu installable from PPA is a disadvantage to me, since now I use Debian exclusively (much better :) ).

      But it doesn’t work in Linux.

      It costs $25.

      It’s not FREE software.
