Software Description

Zulu is a audio DJ program for Windows. This professional DJ software lets you mix music and other audio recordings live. When loading a music track onto a deck Zulu will automatically scan the file for a beat and assign a beat per minute (BPM), and will change the tempo in the second deck for perfect synchronization. Drag and drop music into and around the application's interface and preview an upcoming track through headphones via a secondary audio output.


  • Crossfade in between two tracks.
  • Automatic beat detection.
  • Synchronization between the Decks.
  • Supports a large number of audio file formats including wav (multiple codecs), mp3, vox, gsm, real audio, au, aif, flac, ogg and many more
  • Change the pitch in real time of each track, slow it down or speed it up to manually sync it with the other tracks.
  • Tap tempo, tap space bar in time with the beat to obtain the correct BPM for a track.
  • Manual edit of BPM, input your own BPM value if you think Zulu may have scanned it incorrectly.
  • Hot Key control so you can assign any key or key combination to the buttons and switches on Zulu for faster use.
  • Add a cue pointer marker at any point in a track to instantly start playing the track from that point.
  • Loop sections within a track and syncronize that loop to the BPM.
  • Real time Equalisation on each Deck (track) including "kill" buttons for instant EQ.
  • Apply effects in real-time to a track.
  • Effects include Distortion, High Pass Filter, Reverb, Phaser, Flanger and Delay.
  • Separate output for Professional DJ Headphones.

Yes, it's terrible!

Yes, it's terrible. Pressing the Sync button makes the playback of the playing song jump. Not to mention all the adds it puts in your start menu and that everytime you close the program it will take you the homepage of the program.


Great mixer..except sometimes lost tracks from the playlist. Also, when loading tracks onto one deck, the other deck stopped playing. AND sometimes played the wrong track from the playlist.
