Mix on two proper decks
You can load your own tracks, set cue points, ride tempo, work with sync when you want it, and rehearse complete transitions instead of tapping through a stripped-down demo.
Prep built into the workflow
The mixer analyzes BPM and beatgrid, gives you waveform context, and lets you move straight into loops and phrased entries. The point is practical prep, not decorative metadata.
Review like an adult
Record the master output, listen back, and hear what actually happened: timing drift, crowded low end, rushed exits, and transitions that looked fine until you checked them properly.
What you can do
A browser DJ mixer that behaves like a tool
- Drop in local audio files and build a working library
- See BPM, beatgrid confidence, key, duration, and audio quality checks
- Use hot cues, quantized loops, pitch control, EQ, filters, and crossfader
- Switch between manual control and sync without losing the plot
- Record the master mix for review
- Practice repeatedly without opening a DAW or exporting anything
Under the hood
How the tech supports the workflow
Local decoding and storage
Your browser decodes the files, stores the library locally, and keeps the session private. You are not waiting on a server side import pipeline.
Tempo and beatgrid analysis
The app builds a musical BPM estimate, resolves half-time and double-time mistakes, and uses beat-aligned phase detection so loops and sync stay useful with club music.
Quantized loop handling
Auto loops are snapped to the grid and loop exits preserve audible playback position, which keeps the deck behavior closer to what you expect from real performance gear.
