> QOA is slower than ADPCM, doesn't compress as much as MP3 and sounds worse than FLAC (duh). But I believe it fills a gap that was worth filling.

MP3 compression is very fast on modern hardware. This may have a niche for low power devices, especially if they are battery constrained.

#5What is the LFE channel?
It should be spelled out explicitly, but I figured out the rest
L-Left,R-Right,C-Center,FL-Front Left,FR-FrontRight,SL-SideLeft,SR-SideRight,BL-BackLeft,BR-BackRight
---
Edit: LFE-LowFrequencyEffects... so subwoofer?

Low frequency energy, I assume. Ie bass. Your subwoofer or „bottoms“ if you have several.

It's probably something we (https://overte.org/) can use.
We have a 3D environment with spatial audio. Audio is encoded server-side, and since it's spatial everyone needs their own mix. We're using Opus, and audio encoding turns out to be the usual limiting factor on small servers.
So this kind of thing is exactly up our alley: an alternate option that uses less CPU than Opus, but consumes less bandwidth than raw audio.
But adding supporting for FLAC is also on our list. It seems nicely performant when compared to Opus.

#9What's going to be the next Quite OK thing?
Hopefully a movie format

#10I looked around, but didn't see any mention of potential patent issues. I assume that this has been considered? The Ogg Vorbis people spent a lot of time on that back when they were developing their format.
Other than that, looks great!
