Your own library
Point it at a folder. Every track is analyzed once for BPM, key and loudness, and the results are saved on your computer.
Two decks, a real mixer, stems on any track and effects locked to the beat. Point Listn DJ at your music folder and it works out the BPM, the key and the loudness once, then remembers.
Nothing uploads. Nothing streams. Your set plays from your own laptop.

Point it at a folder. Every track is analyzed once for BPM, key and loudness, and the results are saved on your computer.
Beat sync, hot cues, loops, beat jump, pitch bend and a CDJ-style cue button.
Vocals, melody, bass and drums, separated on your own machine. Play an acapella, drop the drums, bring a bassline in.
Echo, Delay, Reverb, Flanger, Phaser, Crush, Gate and Roll, all timed to the track and its tempo.
Every track at the same loudness, so the gain knob stays where you put it.
19 built-in mappings, lights and meters included, and MIDI Learn for anything else.
Effects
Every effect follows the track's beat grid and its current tempo, so an echo stays in time when you ride the pitch fader. Echo, delay and reverb trail off after you switch them off, the way a club mixer does.

Stems
Listn DJ separates a track into vocals, melody, bass and drums on your own computer. No upload, no subscription. With every stem on, the deck plays the original file untouched.

Nineteen controllers are mapped already: transport, jog wheels, tempo, EQ, pads, loops, effects, lights and level meters. Anything else can be taught with MIDI Learn.
Motorized platters drive the sound like a record. Controllers with their own mixer take each deck on its own outputs.
Everything in Listn DJ, plus four decks, your Listn Cloud library and the tools for a whole night.
Pick a crate and let the app mix each track into the next, on the beat.
Rehearse the next mix in your headphones while the room keeps the one that is on.
Four banks of eight pads, with an air horn, siren and more ready to go.
One press takes the vocal out and puts the lyrics up on a second screen.
The crowd sends song requests from their phones with a QR code.
Broadcast your mix to Icecast or Shoutcast and record an MP3 of the night.
