* **-c** or **--chaptered** Output a single file per chapter. The `--chaptered` will only work if it follows the `--aac -e:m4a -e:m4b --flac` options.
* **--continue &lt;CHAPTERNUMBER&gt;** If the splitting into chapters gets interrupted (e.g. by a weak battery on your laptop) you can go on where the process got interrupted. Just delete the last chapter (which was incompletely generated) and redo the task with "--continue &lt;CHAPTERNUMBER&gt;" where CHAPTERNUMBER is the chapter that got interrupted.
* **--level &lt;COMPRESSIONLEVEL&gt;** Set compression level. May be given for mp3, flac and opus.
* **--keep-artist &lt;FIELD&gt;** In case you don't want to keep all the authors in the metadata, with this flag you can specify a specific field (1 is the first, 2 is the second...)
