djay LE

djay LE transforms your Mac into a full-fledged DJ system, allowing you to mix your iTunes music library on a hyper-realistic turntable interface.

This app automatically analyses a song when it is loaded to calculate its tempo (BPM) and overall volume intensity, as well as finding the exact position of all beats in the song. This allows you to easily and quickly match the gain (volume amplification) and tempo of the two songs in preparation for a smooth transition.
