What is this tool?
A free audio editor that runs in your browser. Open MP3, WAV, M4A, OGG, FLAC or the sound of a video, then trim, cut, split into parts, join files with a crossfade, fade in and out, normalize the volume and change speed or pitch. You can also record from your microphone. Files are edited on your device and never uploaded.
How to Use
- Drop one or more audio files, or press Record to use your microphone.
- Drag on the waveform to select a part, then Trim to keep it or Delete to remove it. Press S to mark split points.
- Use Fade in, Fade out, Normalize, or speed and pitch under Options, for the selection or the whole clip. Ctrl+Z undoes any step.
- Choose WAV or MP3 and press Export. With split points you can download every part as a ZIP.
Frequently Asked Questions
Are my files uploaded?
No. Decoding, editing and MP3 encoding all happen in this browser tab, so the audio stays on your device.
How do I join two songs smoothly?
Open the first file, then press Merge and pick the next one. Set the crossfade length under Options; the end of one track then fades into the start of the next.
Is there a length limit?
Phones handle about 20 minutes at a time and computers up to an hour, so the tab does not run out of memory. Longer recordings can be cut into parts first.
