AtomixMP3 is an MP3-mixing tool that lets you mix on a computer as you would with DJ turntables. With drag-and-drop functionality, the simulated turntables feature pitch control, crossfading, playlist functionality, and visual beat representation. AtomixMP3 also features a real-time, BPM-matching algorithm, and can perform automatic beat-matching in just one click. AtomixMP3 can be used live at a party or at home to record your own mixed CDs or broadcast your own Internet radio. It also features one-click, automatic, seamless loops, real scratch capability, audio CD and WMA compatibility, a completely skinnable interface, and many effects plug-ins.

Version 2.3 adds some features originally developed for new software VirtualDJ, including a browsable playlist and loops representation.
