Anything like this planned for audio ? #185

For example, optimizing Opus for space.

MP3, Ogg, etc are psychoacoustic lossy compression for audio. https://www.xaprb.com/blog/2016/02/21/best-itunes-mp3-format/

May I suggest this is out of scope?

the main "issue" is that guetzli uses Butteraugli to achieve the quality and Butteraugli is it's quality measurement.

However, It is a quality measurement for images. I don't think it works for audio.

You'd need such a thing for audio.

The main idea could probably be applied ti audio but yea seems somewhat out of scope...
