SyncBoss allows for music synchronisation for computers on LAN. Get all your speakers pumping in perfect sync. SyncBoss supports perfect millisecond precise music synchronization over LAN.
SyncBoss transmits music from Winamp to clients who tune in.
Once a DJ is transmitting music & clients have 'tuned in', SyncBoss then actively adjusts the music playing on each computer by altering the speed slightly, to keep each PC playing in perfect sync.
The SyncBoss server transmits all music in real time; it is not necessary to duplicate the music on multiple computers.
