Thanks for listening!

Some clients can use peer-to-peer mode with a STUN server, others can join via a TURN server. There is a sketch on my LAC'20 presentation: http://lac2020.orlandoviols.com/#c12 I have to admit that I am not a network expert, I just added the minimal steps I needed to make it work. Yes, we always make the mix locally (even when the audio is routed via the server). This creates a heavy impact on bandwidth requirements when used with many participants, thus the ovbox works only with relatively small ensembles. The maximum successfully tested number of participants was 12, using a Raspberry Pi. For the concert stream I used a desktop PC with higher performance to create the mix. Since under the hood we use zita-njbridge (with the network data repackaged for the distribution to other peers and/or server), we have one instance of zita-n2j for each musician except the local musicians, which are then fed to the local mix for streaming. Regarding the head tracking we have also two modes: The head tracking can not only affect the way we hear the sound, but also with directional sound sources the ratio between direct and reverberant sound, which could be an interesting effect for singers (right now it is more used as a toy). In the latter case we send the orientation data to all clients to change the rendering accordingly. Best, Giso

Yes, we don't all have the best Internet (cable or low-quality DSL are the most problematic) so connection quality keeps to be a recurring theme but not a deterrent. It's also been surprisingly effective to inject my Solton MS40 arranger with some suitable fixed rhythm into the mix: it teaches everybody where you tend to slow down or speed up and that maintaining one's speed (once it has a chance to be pretty consistent) is reasonably reliable. In addition, it makes it more habitual to listen to a central player (like bass) rather than your "next neighbor". Doing that a few times has a surprising effect on the stability and confidence of the tempo even if you take the drummer out again. And it sure beats the appeal of some metronome. It will be interesting to see what happens when we return to physical rehearsals. -- David Kastrup
