Me too - jamming at about 15ms lag with Jamulus felt really natural. In fact after months of talking to other people through zoom, just chatting with my friends with low latency, high quality, and without the auto processing/muting that zoom seems to do, was amazing. Conversation just flowed back and forth better!
There’s a bunch of similar bits of software but none of them are super welcoming for the less technically inclined. I guess that the experience is often going to be limited by network performance (specifically jitter and loss on UDP) so it’s a challenging thing to make super slick/consistent. I think that low latency 5G with latency guarantees might help solve it when its widely available though.
