Mixxx is an open source computer program for DJing music. Mixxx is cross-platform and supports most common music file formats. It can be controlled with MIDI/HID controllers and timecode vinyl records in addition to computer keyboards and mice.


Mixxx is a DJ Automation and digital DJ performance application[2] and includes many features common to digital DJ solutions as well as some unique ones: It natively supports advanced MIDI and HID DJ controllers, is licensed under the GPL (v2.0 or later) and runs on all major desktop operating systems.[3] The project was started in early 2001 for a doctoral thesis as one of the first digital DJing systems.[4] Over 1,000,000 downloads of the app occur annually and as of Mixxx 1.10.0, 100 developers and artists have helped create Mixxx. Recent versions support harmonic mixing and beatmatching, both manually and automatically.[5]

Hardware/software support[edit]

Audio file support[edit]

Mixxx can read most popular audio formats, including MP3, Ogg Vorbis, Opus, WAVE, AIFF and FLAC. v1.8 introduces a plug-in system to be able to read other formats, including patent-encumbered ones whose decoders cannot legally be distributed in binary form with Mixxx such as M4A/AAC/MP4. Any such plug-ins are automatically loaded at run-time if present.

Audio API/hardware support[edit]

Any sound card that is supported by the operating system is usable in Mixxx. Mixxx supports various software APIs for using sound cards on different operating systems, namely ASIO, WASAPI, and DirectSound on Windows; OSS, ALSA, and JACK on Linux; and CoreAudio on Mac OS X, all via PortAudio.

Controller hardware support[edit]

For external hardware control, Mixxx can support any MIDI or HID controller as long as there is a mapping to tell Mixxx how to interpret the controller's signals. Mixxx includes mappings for many DJ controllers and users can create their own mappings as well.[6] It is the only DJ software capable of using a fully featured programming language, JavaScript, for creating mappings with advanced controller interaction and feedback.[7]

Timecode support[edit]

Turntables and CDJ media players can control Mixxx with the timecode control sub-system which is built on xwax. Like xwax, Mixxx supports timecode vinyl made by several manufacturers.[8]


Mac App Store[edit]

Mixxx is one of the first free and open-source applications available in the Mac App Store. In less than 48 hours since it went live in February 2011[9] Mixxx has become the #1 Top Free App in the USA, Germany, and Italy. [10]

GSoC participation[edit]

Mixxx has been accepted as a mentoring organization in Google Summer of Code 2007, 2008, 2010,[11] 2011,[12] 2012,[13] and 2013.[14]
