 ## Usage
 
+This section addresses the usage of the flac package.
+
 ### Splitting Flac file according to cue file
 
 `shnsplit` can be used to split flac files.
 In the [shnsplit article](/wiki/linux/shntool.md) an explanation on this is given.
+
+### Compress or Recompress `.wav` and `.flac` files
+
+`.flac` and `.wav` files can be compressed with the following command.
+In this `<wav-flac-file>` is the path to the music file but can also use wildcards (for example
+`*.wav`).
+`<compression>` is the compression rate.
+The highest compression preset is `8`.
+
+```sh 
+flac -<compression> <wav-flac-file>
+```
+
+When recompressing `.flac` files the file does not have to be decoded to encode it again but can be
+recompressed in one command.
+
+According to a
+[Reddit comment by berdmayne](https://www.reddit.com/r/foobar2000/comments1m3634l/best_way_to_reduce_flac_file_size_without_losing)
+the compression rates of the different levels are the following.
+
+| Level            | Saving to level 0   | Saving to previous level |
+| ---------------- | ------------------- | ------------------------ |
+| 0 (uncompressed) | 0.0%                |                          |
+| 1                | 0.5%                | 0.5%                     |
