Mixxx is free, cross-platform DJing software with digital vinyl functions . It has been published as free software under the terms of the GNU General Public License (GPL) for all common (desktop) operating systems / platforms ( Windows , macOS , Linux ) since 2002 .
Functionality
Mixxx offers four virtual turntables with pitch control ( pitch shifting ) and automatic beat matching . Either a second channel of the existing sound card or a second sound card can be used for pre-listening without disturbing the main output channel. The software can automatically determine the BPM value of pieces of music and perform beat matching to another piece, which can also be played back at increased or reduced speed while avoiding changes in pitch (by stretching ). If the automatic BPM detection fails, you can manually help by tapping (clicking) the beat. Support for audio formats initially includes MP3 , Ogg Vorbis , WAV , AIFF and FLAC and can be expanded to include other formats using decoder modules .
Mixxx imports any directory that contains the music files into its music library. External music libraries can also be accessed, the Rhythmbox library on Linux and the iTunes library on Windows and Mac . Pieces of music can be organized using playlists as well as so-called crates (English for "box").
If the DJ needs to be absent, an auto-DJ function can be switched on, which plays a certain music selection fully automatically and also does the cross-fading independently.
Mixxx can be controlled via the graphical user interface or external control devices. It also knows the communication patterns for some MIDI controllers and offers a learning function for others. Mixxx can also be controlled using conventional turntables in conjunction with various timecode records . The graphical user interface can be customized with skins .
Mixxx offers an equalizer and filter for post-treatment and can record mix sessions.
technology
The software is written in C ++ and uses Qt for the graphical user interface . In order to support a variety of time code signal formats, the xwax software is integrated as a program library. Code from the SoundTouch program library is used to stretch the audio signal . For particularly low latency and reaction times, JACK can be used for sound output under Linux , which, however, limits the output to one device (sound card). Furthermore, under Windows ASIO , the Windows Audio Session API (WASAPI) and DirectSound , under Linux OSS and ALSA and Core Audio under Mac OS X are supported.
history
The project started in early 2001 as part of a doctoral thesis. In 2007, 2008, 2010 and 2012, the project received several programming grants as part of the Google Summer of Code . After Final Scratch said goodbye to Linux, Mixxx - alongside UltraMixer - is one of the few DJ programs that can run under Linux; There are ready-made installation packages for Debian -based systems, for Debian and Ubuntu they can be found in the software repositories.
