# Audio Cutter

This audio cutter trims a song or recording in your browser. Type a start and end time, or set them from the player while listening, then add optional fades and save as MP3, M4A or iPhone M4R. Cuts are re-encoded, and our tests land within a tenth of a second of the time requested. Nothing is uploaded. The first run downloads a 32 MB engine.

Runs on your device

## How it works

1. Choose an audio file, or a video to cut its sound.
2. Play it and press Start here and End here, or type the times.
3. Add a fade in or fade out if you want one.
4. Pick a format, cut and download.

## Key facts

- **Accuracy**: Within 0.1 seconds in our tests, since the audio is re-encoded rather than cut at packet edges.
- **Time format**: Seconds, or minutes:seconds such as 1:30.5.
- **Past the end**: An end past the file stops at the last sample. A start past the file gives a clear message.
- **Preview**: The player uses your browser. A format it cannot play can still be cut, as our AMR and WMA tests show, but not previewed.

## Common uses

- Removing silence or chatter from the start of a recording.
- Pulling one answer out of a long interview.
- Making an intro with a soft fade for a podcast or video.

## Questions

### Is this lossless?

No. The cut is re-encoded so it can land on the requested time and carry fades. The output is set to 192 kbps.

### Can I remove a section from the middle?

Not with one run. Each run keeps one continuous section.
