What is "ninjam"

NINJAM stands for Novel Intervallic Network Jamming Architecture for Music. The software and systems comprising NINJAM provide a non-realtime mechanism for exchanging audio data across the internet, with a synchronisation mechanism based on musical form. It provides a way for musicians to "jam" (improvise) together over the Internet; it pioneered the concept of "virtual-time" jamming. It was originally developed by Brennan Underwood, Justin Frankel, and Tom Pepper.
