+# Flac
+
+`flac` - short for Free Lossless Audio Codec - is a audio codec without
+compression losses.
+On most distributions it is bundled together with the tagging software
+`metaflac` and other auxiliary tools in the `flac` package.
+
+## Splitting Flac file according to cue file
+
+An easy way to split flac files according to a cue file 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>'
+```
