Getting started

1

Download index.html

Grab index.html from the GitHub repository. No build step needed.
2

Open in your browser

Double-click the file. Chrome, Edge, or Firefox are recommended. Firefox may show a security prompt for local file access — click Allow.
3

Wait for tracks to generate

The 11 built-in tracks are synthesized on first load using an OfflineAudioContext. This takes a few seconds and only happens once per session.
4

Start mixing

Select a track from the drop-down on each deck, press PLAY, and drag the crossfader to blend between them.
Use headphones or external speakers for the best experience. NEON DJ targets the full stereo frequency range — bass synthesis and reverb tails are much more noticeable on good audio hardware.
