Beat Browser is a music browsing environment that delivers immediate audio feedback while browsing arbitrarily large music collections.
The goal of Beat Browser is to give users a sense of exploring "live" and continuous audio while rapidly moving between sources by mouse.
It appears their entire universe of music is playing all the time, whether they're there listening or not.
Beat Browser's Universal Time Base architecture keeps a central clock running that manages the playback position of every piece of music launched, orchestrating this perceptual illusion.
