jit.catch~ / jit.release~ (to convert audio signal into matrices)
jit.net.send / jit.net.recv (for TCP/IP, don't know if this will work with your wireless setup, but it's matrix-ready)
otherwise, udpsend / udpreceive, but you'd need to convert the matrices (or the audio itself) to packets that work with udp.
Get the jit.catch~ working and try jit.net.send first. Curious to hear if you get it going, and what kind of latency or bandwidth issues you run into.
The thing is a total bandwidth hog. I can send streaming or live video all day long and it comes through as a light lunch. Max Msp and gen~ could really do with some cool audio compressor tools for peer to peer, non server based audio compression. Anyone?
