### MP3 Encoding ### MP3 Encoding
* This is the default encoding
* Produces 1 or more mp3 files for the AAX title. If you desire a single file use the **--single** option * Produces 1 or more mp3 files for the AAX title. If you desire a single file use the **--single** option
* If you want a mp3 file per chapter do not use the -single option. Note a m3u playlist file will also be created in this instance. * If you want a mp3 file per chapter do not use the -single option. Note a m3u playlist file will also be created in this instance.
* If you desire flac encoding. use the **--flac** option. It's a bit faster but also a bit less compatible.
### M4A Encoding ### Ogg/Opus Encoding
* Can be done by using the -o or --opus command line switches
* Is designed to efficiently code speech and general audio in a single format
* Opus coded files are stored in the ogg container format for better compatibilitt.
### AAC Encoding
* Can be done by using the -a or --aac command line switches
* Designed to be the successor of the MP3 format
* Generally achieves better sound quality than MP3 at the same bit rate.
* This will only produce 1 audio file as output.
### FLAC Encoding
* Can be done by using the -f or --flac command line switches
* FLAC is an open format with royalty-free licensing
### M4B Encoding ### M4B Encoding
