Audio Studio —
compose your recordings.
Pull clips from your local library onto one timeline, trim and split them, put them in order, and render one clean take — then send it straight to transcription. Everything runs in this tab; nothing is uploaded, no signup.

Checking local library…
No clips yet — record one in the voice recorder, it saves here automatically, or drop an audio file above.

Drag across the waveform to set the trim window. Click anywhere to place the playhead, then split there.
Add clips from your local library or drop a file to start your timeline.

Composing a take shouldn't require an upload
The timeline reads and writes to your browser's local library only. Decoding, trimming, arranging, and rendering all happen with the Web Audio API in this tab — no server ever sees your recordings.
Your library stays local
Clips are read from and saved to IndexedDB in this browser — no network call, ever.
Nothing is mutated until you render
The timeline is just trim windows into your clips. Source recordings are never overwritten.
Your draft autosaves, locally
The arrangement saves to this browser as you work and restores when you come back.
Five steps to one clean take
Build the timeline from clips you already have, shape each one without touching the original, and export when the arrangement reads right.
- 1
Add clips
Pull recordings from your local library, or drop a file — it's saved there first.
- 2
Trim & split
Select an item to open the inspector, drag its trim window, or split it at the playhead.
- 3
Arrange
Reorder with the arrows or a drag, and add a gap after any item that needs a beat of space.
- 4
Render
Preview the whole arrangement, then render one WAV — download it or save it to your library.
- 5
Transcribe
Jump straight from a saved take into the free transcribe tool — still no upload.
A few reasons people build a timeline first
Composing voice memos into one take
A few short recordings capture the same idea in pieces. Bring them onto the timeline, trim the false starts off each one, order them, and render a single clean take instead of stitching them by hand.
Prepping a long recording for transcription
Split a long session at its natural breaks, drop the parts you don't need, and render just the parts that matter — then send the result straight into the transcribe tool.
Your library connects the free tools
Anything saved by the voice recorder, trimmer, splitter, or merger shows up here to build on — and anything you render here shows up back in those tools too. One local library, no accounts, no uploads.
Record, merge, trim, split, and transcribe too — all local
Need a take before you compose with it? Use the free voice recorder. For a quick one-shot job on a single file — no timeline, no arranging — the standalone merger, trimmer, and splitter are still there and still free. Once your take is ready, the transcribe tool turns it into text — still no upload.
Audio studio FAQ
Does the studio change my original recordings?
No. The timeline never touches the audio in your local library — each item on it is just a trim window into a clip, plus an optional gap. You can rearrange, trim, and split as much as you like; the source clip stays exactly as it was until you explicitly render a final take.
What happens to a file I drop onto the studio?
It is decoded locally, saved into your local library as a new recording (so it shows up in the voice recorder and transcribe tool too), and then added to the timeline. Nothing is uploaded — the save is just local browser storage.
Will I lose my arrangement if I close the tab?
No. The timeline autosaves to this browser as you work, and restores when you come back. If a clip you used gets deleted from your library in the meantime, that one item is dropped with a one-line notice — everything else stays put.
What does "Split at playhead" actually do?
It cuts the selected timeline item into two items at the current playhead position, both still pointing at the same source clip with adjacent trim windows. It refuses to make a split that would leave either half shorter than half a second.
What format is the rendered take, and can I keep editing after?
A standard 16-bit PCM WAV, resampled to the highest sample rate among your clips (capped at 48kHz). Rendering does not lock your timeline — the arrangement stays editable, and you can render again after making changes.
Is there a limit on how many clips I can arrange?
No hard cap — everything runs in this browser tab, so the practical limit is your device's memory. Long arrangements with many clips will take a little longer to render.
