Audio Quick Look - after previewing 3 or 4 tracks, freezes for 20 seconds

Is this a known thing?

Definitely not a known thing. I need a little more details to understand the issue. What OS? What computer? What kind of sound format? How long are the sounds? Where are they stored?

I’ve just tried to recreate this with all sample rates, short tracks, long tracks etc and could not. Must have been an OS thing rather than audiofinder. As you were!

Sounds good, keep me posted. Working on updates for Big Sur and hunting down bugs and issues.
