In case you're not aware, I'm one of the authors of Opus. :P When the pandemic hit I thought about putting out some pointers to easier to use low latency streaming resources... but... that would require overcoming pandemic lockdown funk. And honestly it's still kind of a technical rats nest to get everything working. It's not exactly musician friendly to need instructions like "next you need to make sure your nic doesn't enable interrupt mitigation when there are more than 100 packets per second...". :) [I love Jack BTW.]

Another example of HN being amazing. In the interest of playing too, I did some work on reducing audio latency in Android, but that all predated AAudio/Oboe, which takes that quite a bit further and makes at least the Pixel devices a plausible platform for low-latency audio collaboration apps as suggested in this thread. I for one would love to see that happen - I miss singing hymns on Sunday mornings.

Yeah, I'm really sad that I didn't get some serious effort together on this back at the start of the year. There's no lockdown funk here, just too busy working on Ardour. One of the 2 netjack implementations uses Opus - great stuff. Absolutely right that the good stuff (i.e. not zoom) requires way too much setup, and even then (as you note) you're not guaranteed reliable function because you don't control all the hops. Soundjack gets the user-side fairly good, but it's still not quite what I think would have really taken off during the pandemic - probably needs a mobile app for that.

I love libopus! I use it as one of the codecs for my low latency streaming library “AOO“ https://git.iem.at/cm/aoo https://git.iem.at/cm/aoo

  And I love AOO, I use it as the basis for SonoBus.... I’ve been meaning to contact you about it, and work on merging your latest into my fork (which has diverged a bit over the last few months). And hey Paul, long time no chat! https://sonobus.net https://sonobus.net
