have you considered using webtransport?

When I was developing Glicol (https://glicol.org/) sync, the main challenge is network jitter. Had to give it up eventually.

Furthermore, have you factored in the synchronization as perceived by the listener?

Also, it seems system-level differences, particularly in audio output latency across various OS and hardware setups, would need to be considered.

What I mean is, the variation in inherent audio output latency between different systems (e.g., Mac vs. Windows, different hardware) could easily exceed 10ms in itself.

Practically, the network jitter is averaged out in the clock synchronization calculations, and even output latency is remarkably well-behaved. Have you tried it on different devices? It is only noticeable when there's an external device connected to the computer.
