 ### Splitting Flac file according to cue file
 
-An easy way to split flac files according to a [cue file](../cue_sheet.md) is
-using `cuebreakpoints` and `shnsplit`.
-On most distributions they are in a package with the same name.
-The following line of shell command splits a flac file according to a cue file.
-The `-o` tag specifies the output file format.
-
-```sh
-cuebreakpoints '<cue file>' | shnsplit -o flac '<audio flac file>'
-```
-
-Omitting of the `-o` flag will result in output files with the `.wav` filetype.
-Alternatively the usage of `cuebreakpoints` can be avoided with the following
-command.
-
-```sh
- shnsplit -f '<cue file>' -o flac '<audio flac file>'
-```
-
-Another option is to use [`cue2tracks`](https://github.com/ar-lex/cue2tracks).
-This has the advantage that tags for album title, song name and others are set
-while splitting the files.
-An example command looks like the following.
-The `.flac` file is not mentioned in the command.
-
-```sh
-cue2tracks '<cue file>'
-```
-
-For any of these commands there can be problems with splitting `.flac` files.
-It then is recommended to convert the file to the also lossless `.wav` format,
-split the files and convert it back to `.flac`.
-
-High quality flac files with older `.cue` files that use the format `mm:ss:ff`
-might split the file at the wrong timings.
-The format `mm:ss:ff` is not compatible with the newer versions of
-cuebreakpoints, cue2tracks and shnsplit.
-To get the correct timings the `.cue` file has to be changed to use the format
-`mm:ss:fff`.
-It is recommended to use the shnsplit alternative in this case.
+`shnsplit` can be used to split flac files.
+In the [shnsplit article](/wiki/linux/shnsplit.md) an explanation on this is given.

+# shntool
+
+[shntool](http://shnutils.freeshell.org/shntool/) is a multi-purpose data processing utility.
+With it audio files of a wide array of codecs - like [flac](/wiki/flac_%28codec%29.md) - can be
+edited.
+
+## Setup
+
+shntool can be installed on most distributions by installing the `shntool` package.
+
+## Usage
+
+### Splitting Audio Files According to a CUE File
+
+An easy way to split audio files according to a [cue file](../cue_sheet.md) is
+using `shnsplit`.
+Alternatively the interface `cuebreakpoints` can be used which uses `shnsplit`.
+Note that some codecs require special setup.
+These codecs are referenced in the end of this section.
+
+The following line of shell command splits an audio file according to a cue file.
+The `-o` tag specifies the output file format - for example `flac`.
+
+```sh
+cuebreakpoints '<cue file>' | shnsplit -o '<codec>' '<audio file>'
+```
+
+Omitting of the `-o` flag will result in output files with the `.wav` filetype.
+Alternatively the usage of `cuebreakpoints` can be avoided with the following
+command.
+
+```sh
+ shnsplit -f '<cue file>' -o '<codec>' '<audio file>'
+```
+
+Another option is to use [`cue2tracks`](https://github.com/ar-lex/cue2tracks).
+This has the advantage that tags for album title, song name and others are set
+while splitting the files.
+An example command looks like the following.
+The audio file is not mentioned in the command.
+
+```sh
+cue2tracks '<cue file>'
+```
+
+For any of these commands there can be problems with splitting files.
+It then is recommended to convert the file to the also lossless `.wav` format,
+split the files and convert it back to the desired codec.
+
+For `ape` files a special package needs to be installed to be able to split them.
+This package is called `flacon`.
+It is normally used as a GUI for `shntool` but comes with the codecs needed.
+It is usually available in a package of the name `flacon`.
+On Ubuntu systems the repository first has to be added by running the following command.
+
+```sh
+add-apt-repository -y ppa:flacon
+```
+
+Afterwards `flacon` can be installed like a normal package.
+
+## Troubleshooting
+
+### Unable to Split Audio Files
+
+This error occurs when
+[splitting audio files according to cue files](#splitting-audio-files-according-to-a-cue-file).
+High quality flac files with older `.cue` files that use the format `mm:ss:ff`
+might split the file at the wrong timings.
+The format `mm:ss:ff` is not compatible with the newer versions of
+cuebreakpoints, cue2tracks and shnsplit.
+To get the correct timings the `.cue` file has to be changed to use the format
+`mm:ss:fff`.
+It is recommended to use the shnsplit alternative in this case.
