A browser-based multitrack audio editor that lets you drag, trim, slice, and layer clips on a pixel-accurate timeline — with full undo/redo, debounced autosave, and named version snapshots.
Every clip sits on a lane colour-coded by kind — voiceover, music, SFX. Drag to move across the timeline or across tracks. Trim the start or end of any clip by dragging its handle. A snap system locks clip edges to the grid, the playhead, and neighbouring clip boundaries so your mix stays tight without pixel-hunting.
Every edit — move, trim, slice, add, delete — is undoable and redoable via a 100-step in-memory stack (Cmd+Z / Cmd+Shift+Z). Edits are also debounced-saved to the server automatically after 1.5 seconds of inactivity, so you never lose work. Named version snapshots let you checkpoint a milestone ("Before final mix") and restore it at any time.
Click "Add clip" to open the asset picker — a sliding panel listing every voiceover and music track in your library with kind filter, title search, and an inline play button for a quick listen. Selecting a track drops it onto the matching kind's lane at the current playhead position, with the presigned URL already wired so the engine resolves it immediately.
Each clip block renders its waveform — a visual fingerprint that makes it easy to see phrase boundaries, silence gaps, and music sections at a glance. Zoom controls adjust pixels-per-second so you can work at the level of the whole mix or zoom into a half-second splice point.
