opusfile

https://opus-codec.org/

Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications.

My intention were to use the Opus codec for game assets with OpenAL. There's examples/openal-playfile exactly for this.

You'll need libopusfile-dev or something like that for your distro.

Add to package dependencies and import Sound.OpusFile qualified.
