Don is trying to use both Skype and Zoom for his music rehearsals. But the latency is terrible. So he's been using another option called Jamulus. Why does that work, but Skype doesn't? Leo says that distance is a factor, but there's also networks, bandwidth, the kind of network, network connection speeds, ISPs, switches, all contribute to latency. Jamulus is nice because it's open-source and free. But there are also commercial options like Jammr. From the Chatroom - CleanFeed.
