An open source DJ tool

Mixxx is designed for DJ'ing for both professional and
semi-professional users.
Mixxx was started in early 2001 as one of the first digital
DJ systems.

Today Mixxx includes many features common to digital DJ solutions,
but also some very unique features: It is free, and runs on all
major desktop operating systems.

Furthermore Mixxx has a number of key features to help the DJ in
the live mix: Beat estimation, parallel visual displays, and
support for many DJ input controllers.

Mixxx is software for DJ'ing. You can use wave based audio files,
Ogg Vorbis and MP3 files as audio input. Mixxx can be controlled
through the GUI and with external controllers including MIDI
devices, joysticks and more.
