The script (convert.bash) converts directories with releases (e.g., a music album as a single directory with audio files as tracks inside) from lossless formats (FLAC, WAV) to the Opus format. The goal is to minimize the size of the audio files while preserving the quality of the music as much as possible.
The only dependency is FFmpeg. Your build should support codecs for the mentioned formats.
Here's an example of downloading a release via streamrip and running the script on it:
