Low latency queues in Rust ecosystem
Thanks! Your link lead me to https://github.com/mgeier/rtrb/issues/39 where they compare to different queues. Exactly what I was looking for. Thank you again!

Cueue - a truly circular SPSC queue
Nice! Would love to see benchmarks against the other ring buffer crates, like in these comparisons: https://github.com/mgeier/rtrb/issues/39

What’s everyone working on this week (2/2022)?
I'm continuing to work on a new musical live performance software, Moiré. I just figured out how to make use of dynamically sized Vecs without allocating or deallocating in the audio thread using basedrop and rtrb. I'm using SixtyFPS for the GUI.

Audio Libraries Considered Challenging
I agree. It's when you get down to "musician audio" things get problematic w r t allocation, both because of the latency and because of the audio being the primary thing you care about. That's also when you start to get issues with the kernel not scheduling your thread and so on. If you're curious about kernel issues, you can read a presentation I did five years ago. Maybe the Linux kernel has improved since.
