Every other mixer gives you left, right and loud. Azimuth gives each deck a position around the listener's head — so a track can sit behind them, arrive from ahead, or orbit while you mix. Two decks, real key-lock, multi-touch scratching, MIDI. Nothing to install, no account, and your files never leave the machine.

Every DJ tool makes you trade one thing for another. The desktop suites are powerful and assume a laptop, a controller and a subscription before you have played a single track. The mobile apps proved that a touchscreen makes a fine mixer, then locked it to an app store and one platform. The browser tools ask nothing of you and give back a thin, laggy imitation.
None of those trades are necessary any more. AudioWorklets run the audio on its own thread, so a browser tab can hold a sample-accurate playhead without the interface stealing time from it. That is what makes a real instrument possible here — and once the engine is doing that much, giving every deck a position in three dimensions is a capability nothing else in the category has bothered to build.
A normal mixer gives you left, right and loud. Azimuth puts a spatial field in the middle of the mixer: leave deck A orbiting behind the listener and bring deck B in from dead ahead. The eight-bar spatial transition does the handover on beat, and each deck can follow its own path at its own tempo.
Every control captures its own pointer, so a touchscreen behaves like hardware. Hold the platter with one hand to backcue or scratch while the other rides the crossfader or kills a band on the EQ. Both decks can be scratched at once.
Time-stretching needs a window of upcoming audio, and grabbing the platter destroys it. Azimuth hands off to true varispeed — pitching the way vinyl does — for as long as you hold on, then crossfades back to pitch-locked playback when you let go.
Waveforms are split into low, mid and high bands at 150 buckets a second, so kicks, vocal breakdowns and drops are visible ahead of the playhead. A Goertzel filter bank reads each track's key and checks both against the Camelot wheel.
| Audio engine | AudioWorklet playhead with sample-accurate DSP, off the main thread |
|---|---|
| Spatial | 360° placement per deck, distance roll-off, elevation, beat-synced orbits and transitions |
| Beat and key | Automatic BPM with autocorrelation fallback, beatgrid alignment, Goertzel key analysis, Camelot matching |
| Deck controls | Cue preview, 4 hot cues, beat loops, momentary beat rolls, motor brake, needle-drop, beat-bend, trim |
| EQ and effects | 3-band isolator EQ with kill, sweepable filter, reverb, tempo-synced echo with a rotating spatial repeat |
| Pads | Hot cues, loops and rolls, plus chop mode — the loaded track sliced across the pads, each slice at its own point around you |
| Monitoring | Split-mono headphone cueing through one stereo output; a real second output device where the browser supports it |
| Control | Web MIDI on Chrome, Edge and Opera — every deck and mixer control mappable, learned rather than guessed |
| Second screen | Deck, mixer or the spatial field alone, mirrored to another window or display over BroadcastChannel |
| Recording | Lossless WAV or Opus off the master, limited so the capture matches what you heard |
| Also included | A step-sequenced drum machine with per-track spatial placement, a bassline, a four-slot loop station, and the 8D renderer |
All of the above is free and working today. The gap, stated plainly: there is no track library, so a reload loses your crates and cues.That is what Pro is for.
Yes. The layout breaks on aspect ratio rather than screen width, so a phone held in landscape gets the full rig — a landscape phone is already mixer-shaped. Portrait shows one deck and an A/B switch. Multi-touch works throughout, so you can scratch with one hand and move the crossfader with the other.
Azimuth has a split-cue mode. With a standard 3.5mm splitter cable the master mix goes to one channel and the cued deck to the other, so a single headphone output covers both jobs without a second sound card. Where the browser supports selecting output devices, the cue bus can also have a real second device of its own.
No to both. It runs in any modern browser on the Web Audio API and AudioWorklets. There is no plugin, no download and no sign-up, and the tracks you load never leave your machine.
Ordinary stereo can only place a sound between your two ears. Binaural rendering recreates the small timing and tonal differences your ears use to locate a sound, so a deck can sit behind you, above you or off to one side. Spatial DJing is mixing where each deck has its own position in that field, so a transition can happen in space as well as in level. It needs headphones — over speakers both ears hear both channels and the effect collapses.
Yes, and it is free. Web MIDI is supported on Chrome, Edge and Opera, and every control on both decks and the mixer can be mapped. No default mapping ships — controllers disagree about note and CC numbers badly enough that a guess is worse than nothing — so each binding is learned by arming an action and touching the control, then saved in your browser. Not yet supported: LED feedback back to the controller, and MIDI clock.
The whole instrument is free, including MIDI, spatial mixing, recording and the drum machine. That is deliberate rather than generous: everything here runs in your browser, and a paywall in front of readable JavaScript is theatre. The paid tiers cover what genuinely needs a server — your crates, cues, beatgrids and mappings following you between machines, and publishing mixes.
There is no track library. You load a file per deck each session, and a reload loses your crates and cues — that gap is exactly what the Pro tier is being built to close. Stem separation is planned as a free, on-device download rather than a paid feature. MIDI is limited to browsers that implement Web MIDI, which excludes Safari.
