Mumble

Mumble is primarily intended for gamers, and was the first to establish true low latency voice communication over a decade ago, but finds good use in many different environments as well, Over 3.000 changes (or “commits”) make up this release compared to our previous stable version 1.2.19 (GitHub compare). These changes include over 1.600 first-parent commits.

wow, talk about a come back, maybe they had a look around and realised that actually nothing else out there really came ever as close as mumble (ok, teamspeak maybe) when it came to low latency. i'm pretty sure most of them were using the opus codec for everything but there ya go.

back after a decade, v1.3.0 and LOTS of changes in that time from what looks to be a huge amount of contributors. i thought the project was dead. seems not!
