# Opusab
Create Opus audiobooks from a folder of mp3 files. Opus offers ~4x smaller file sizes compared to mp3 without losing in quality.
```
OVERVIEW: Create Opus audiobooks from a list of mp3 files
USAGE: opusab files...
OPTIONS:
--bitrate, -b bitrate in kbits (default 32)
--cover path to the cover file
--dry-run, -n print command but do not execute it
--output, -o name of the output file
--verbose, -v verbose output
--help Display available options
POSITIONAL ARGUMENTS:
files audio files
```
**This is work in progress. Suggestions and PRs are very welcome!**
## Installation
```
brew install nikstar/tap/opusab --HEAD
```
*Please use the up-to-date `--HEAD` version until **opusab** reaches 1.0*
## Bitrates
+ 48 kbit/s or higher should only be used for high quality sources with occasional background music
+ 32 kbit/s is a **good default** that should be used to convert, for example, 120 kbit/s mp3s
+ 24 kbit/s offers good quality and I personally cannot tell difference from 32 kbit/s, but you might :)
+ 16 kbit/s is perfectly intelligible and gives you tiny files at just **7.2 MB per hour**
