🦋 DESCRIPTION 🦋

So jack_netsource is, like, the Master side of a netjack connection. It literally stands in for the slave jackd -dnet inside your master jack graph, main character energy fr fr. 👑

Most of the connection parameters get configured via the netsource, and the slave will set itself up according to the commandline option given to jack_netsource. no cap.

Netjack allows low latency audio connections over general IP networks. And when you're using opus for compression? bestie, it is even possible to establish transatlantic links 🌈 with latencies not much over the actual ping time. iconic. But the main usecase is of course a LAN, where it can achieve one jack period of latency. ✨

🌈 EXAMPLES 🌈

okay so here's the vibe: run a 4 audio channel bidirectional link with one period of latency and no midi channels. Audio data is flowing uncompressed over the wire. periodt. 💫

On hostA:

jackd -d alsa
jack_netsource -H hostB -n1 -i4 -o4 -I0 -O0

On hostB:

jackd -d net
