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.

Can you tell us which ai minion(s) helped you with this?

This is included in 1.1.4. call interface now displays when other side is recording and optionally configure a preset chimes or record a custom notification sound.

When remote is detected as recording this sound will play if the setting is enabled.

there are ways to help with lag a bit, you can choose the number of hops a HS uses when meeting up. but of course that comes with downsides

I'm going to look into this. I guess you loose anonymity, but in scenerios where that doesn't matter could be a fine trade off for speed.
