This is a 3D interactive simulation of a DJ setup with two turntables and a mixer.
You can crossfade, backspin, speed up and slow down music, including full-length WAVE and MP3 songs. You can use it to mix like a DJ or let it mix your MP3 playlist automatically.
It provides support for mixing music from your hard drive, including MP3 files. You can cue with headphones because it can play back the cue record on the left channel.
WAVE, MP3, AIFF and other sound formats supported by QuickTime are supported by this tool.
