Audio editing,
made pleasant.
A modern audio editor that opens in a tab. Beat-aware cuts, region-based non-destructive edits, and a waveform you can easily navigate and zoom.
Audio Editor
Web apps caught up desktop editors
You shouldn't need to install a desktop app from 2002 just to trim a podcast intro. We rebuilt the experience from scratch — fast, focused, and browser-native.
Open a tab. Edit. Done.
- Loads in seconds, no install
- Non-destructive regions, real undo
- Designed in this decade
Focusing on what matters the most.
Intuitive Waveform Zooming.
Pinch, scroll, or scrub — the waveform stays sharp from the whole song down to a single sample. The cursor stays where you're looking, every time.
Snap to the beat.
The editor analyses the track and places markers at every beat. Snap your cuts to beats, seconds, or region boundaries — precise edits in one click instead of ten.
Record straight into local disc (Chromium based browsers).
In Chrome and Edge it streams to a file on your disk as you record, so a long interview is limited by disk space, not memory. Even if browser crashes your recording was preserved.
Region-based, non-destructive.
Split, merge, trim, and rearrange — your source audio is never touched. Try ten ideas, undo eight, keep the two that work. Nothing is permanent until you export.
Export as MP3 or WAV.
One menu, one click. Render the full track or just a selected region — locally to disk or directly to your Puter cloud.
Built on Puter
Audio Editor is a Puter app. Puter is an open-source, browser-based personal cloud — your files, apps, and storage, all in a tab. No install, no lock-in, no servers to set up.
Your cloud, your files
Audio you edit lives in your own Puter drive. Open from cloud, save back to cloud — same files, same place, every device.
Open source & private
Puter is open source. Self-host it, audit it, fork it. Your audio never leaves your browser unless you ask it to.
Instant, every time
No installer. No update prompts. The editor loads as a webpage and runs at native speed, on any modern browser.

Frequently asked.
Is Audio Editor really free?
Yes. The editor is free to use and runs entirely in your browser. A free Puter account unlocks cloud storage, sync, and shared files — but you don't need one to edit and export.
Do I need to install anything?
No. Open the page, drop in an audio file, and start editing. There's nothing to download.
Can I record audio with it?
Yes — pick any microphone or audio interface, watch the input meter, and the take lands on the timeline as a region. In Chrome and Edge you can record straight to a file you choose, which keeps memory flat and means length is limited only by disk space. Other browsers record into memory, up to 20 minutes per take.
What audio formats can I import and export?
Most common formats import (MP3, WAV, M4A, FLAC, OGG). Exports go out as MP3 (320 kbps) or WAV (16-bit).
Is my audio uploaded to a server?
Editing happens locally in your browser. Files only sync to the cloud if you choose to save them there via Puter.
How does beat detection work?
When you import a track, the editor analyses it and places beat markers along the timeline. You can snap edits to those markers, or to seconds and region boundaries — toggle each independently.
What does "non-destructive" mean?
Splits, merges, trims, and rearrangements are stored as a project — your source audio file is never modified. Undo any change at any time. Render only when you export.
Open a tab. Edit some audio.
