Online Multitrack Audio Editor

Build quick DJ edits and layered arrangements in a browser-based multitrack workspace using only implemented editor features.

Supported formats: WAV

What this tool actually does

Build quick DJ edits and layered arrangements in a browser-based multitrack workspace using only implemented editor features.

Create and remove tracks: addTrack and removeTrack live in the timeline model, and the editor adds a dedicated track when you import audio.

Move, trim, split, duplicate and delete clips without touching the original audio, and copy and paste clips with the Copy and Paste tools over a dedicated clipboard.

A single effect registry drives both realtime monitoring and offline rendering, with parametric EQ, compressor, multiband compressor and brickwall limiter registered out of the box.

Save and reopen the whole project as a .deckproj ZIP that bundles its audio, with older project versions migrated on decode.

Export the master mixdown by rendering the timeline with an OfflineAudioContext and downloading it as a 16-bit stereo WAV.

Work on a musical grid: divisions from 1/1 to 1/32 including triplets, time-to-bar conversion and snap of clips to the grid lines.

Split a track into four stems —drums, bass, instrumental and vocals— and drop them in as new project tracks.

Real-world use cases

What people actually solve with this converter before they play live.

Prepare tracks before a DJ set.

Fix or process files without opening a full DAW.

Keep the workflow focused on the specific task instead of a general-purpose editor.
