Description

"With the open source programm Ninjam musicians can jam together in an internet conference. You can listen all your conference partners playing and jam with them - a virtual band rehearsal. Concerning synchronization: Ninjam gets everyone playing at 120 bpm (beats per minute) with a click track. Every audio track is delayed by a certain amount, so everyone has all the others synchronized on his earphones. Many artists create songs solely over the internet, together with musicians they met on Ninjam." (http://thinnerism.cc/2007/10/28/music20-overview-–-part-3-justin-frankel-winamp-gnutella-and-ninjam/)
