How to use

Edit audio without leaving the browser.

Use the wide waveform workbench for selection, timeline edits, preview, cleanup, and export.

Step 1

Step 1 Load an audio file
Load a browser-decodable audio file such as MP3, WAV, M4A, AAC, OGG, or FLAC. The original copy is not changed.
Step 2

Step 2 Select the part you want to edit
Drag across the waveform, move the blue handles, or place the playhead and use Set start/end at cursor for precise cuts.
Step 3

Step 3 Apply edits and review
Cut, trim, silence, fade, normalize, reverse, remove gaps, then use undo/redo if the edit needs another pass.
Step 4

Step 4 Export a clean copy
Choose MP3 quality or WAV, optionally apply full-export cleanup, and download a new edited file.

Use Cases

Built for practical audio cleanup jobs.

These are the common workflows where a wider editor surface makes the page easier to use than a narrow calculator-style layout.

Trim voice notes and meetings

Remove dead air at the beginning or end, cut mistakes, and export a smaller MP3 for sharing.

Suggested workflow: Best tools: trim, cut selection, silence selection, MP3 128 or 192 kbps.

Clean podcast clips

Normalize quiet speech, remove long gaps, fade selected sections, and keep an editable copy before publishing.

Suggested workflow: Best tools: normalize selection, remove gaps, fade selection, WAV export for further editing.

Create quick audio effects

Reverse a selected phrase, fade a transition, silence a noisy section, or isolate a short sample from a longer file.

Suggested workflow: Best tools: reverse selection, trim to selection, play selection, zoom selection.

Prepare files for other tools

Make a shorter source file before using the metadata editor, compressor, ringtone maker, or waveform video maker.

Suggested workflow: Best tools: export cleanup, MP3 192 kbps, WAV PCM when quality matters.

FAQ

Online audio editor questions.

Quick answers about privacy, export formats, undo, and browser performance.

Is the audio uploaded to a server?

No. The editor decodes, edits, previews, and exports the audio in your browser. The original file stays on your device.

Why does this page need more width than other tools?

Waveform editing needs horizontal space for precise selection, zooming, handle dragging, transport controls, and export settings. This page uses a wider workbench layout for that reason.

Can I undo an edit?

Yes. The editor keeps a short local undo history during the browser session, plus redo for edits you restore.

Which export format should I choose?

Use MP3 128 kbps for smaller voice files, MP3 192 kbps for balanced sharing, MP3 256 kbps for better quality, or WAV PCM when you want an uncompressed editing copy.

Why can very large files feel slow?

Browser audio editing uses local memory and CPU. Long recordings need more time to decode, draw, process, and export.
