What is Audio Workspace?
Audio Workspace opens many audio files in one place — trim, denoise, change pitch & speed, normalize volume, and re-encode to MP3/WAV/OGG/M4A/FLAC. Every edit is non-destructive and the originals never leave your device. Switch between independent workspace tabs to keep podcast edits, music exports and voice cleanup separated.

Use cases
- Edit a podcast — trim the intro, denoise the room, then export an MP3 in one pass.
- Prepare music files for upload: convert to FLAC for archive and MP3 for streaming.
- Pitch-shift voice memos or transpose practice tracks without changing speed.
- Compress a folder of WAV files to small voice-grade MP3s for sharing.
Frequently asked questions
Is anything uploaded to a server?
No. FFmpeg.wasm runs entirely in your browser. The first export downloads the engine (~30 MB) once and caches it.
Are my edits saved across reloads?
Yes. Files and per-track edits live in IndexedDB inside your browser profile. Clearing site data wipes them.
Is Audio Workspace free?
Yes — Audio Workspace is completely free with no paywall, trials or usage caps. Every TabTasker tool is free forever.
Does Audio Workspace work offline and keep my files private?
Yes. Audio Workspace runs 100% client-side in your browser using Web Workers and modern browser APIs. Your files are never uploaded and it keeps working offline once the page has loaded.
Is this audio editor tool better than online tools that upload my files?
For privacy, yes. Most online audio editor services upload your files to a server. TabTasker does everything locally, so nothing leaves your device — ideal for sensitive or confidential documents.
Do I need to create an account or install anything?
No. No account, no extension and no install — just open the page and start. It works on any modern browser, desktop or mobile.
