Using a v3 onion address as both the cryptographic identity and the NAT traversal layer is such a clean architectural choice. No STUN/TURN servers, no hole punching, you just boot the script and Tor handles routing.

For those who use Tor regularly for things other than web browsing: how bad is the real-world latency for pushing a ~20KB Opus audio chunk over Tor these days? Are we talking a 2-3 second delay, or is it much worse?

The real world delay is about 2-3 seconds your spot on. I initially started with a full duplex version but it was absolutely terrible. Walkie talkie kinda forces the recieve, listen, response from the users so the latency isn't as much of an issue.

Is audio transmitted while it is being recorded or afterwards? Is it played before everything is received or is everything buffered? In the later case, I find it more akin an audio message on Signal or similar, than as a walkie-talkie, which is much more "dynamic".

It's not streamed. It gets recorded, compressed, (voice effects if you want), encrypted on device, then piped through, reverse process, auto played on reciever end.

Also, once it's decrypted and played back, the message gets destroyed.

Small suggestion, maybe you should send a “key down” notice when you begin recording, that generates a subtle sound on the receiving end. This would act as something like a typing indicator on a text messaging client.

		Thats a great idea.

STUN/TUN are important because of bandwidth. With STUN the bandwidth used is only between the two connected devices, with VPN like Tor there is a bandwidth cost on all the servers where this data is passing. This is a big blocker for anyone hosting the service on a VPS with a few GB of traffic data per month.
