Audio Cutter cuts a part out of an MP3 or any other audio file. Drag across the waveform (or type the times), add a fade in and out, and save as MP3, WAV, M4A, FLAC or OGG. It runs in your browser, so nothing is uploaded.
How to cut audio
- Choose an audio file (or a video).
- Drag across the waveform to select the part, or type From and To.
- Choose to keep the selection or remove it, add fades if you like, and click Cut.
- Listen to the result in the preview. If it is not right, change the times and click Cut again; the original file is still loaded.
Typing exact times
The waveform is quick for a rough selection; the time boxes are for precision. Both accept minutes and seconds with decimals, such as 0:15, 2:03.5 or 1:23.45, or seconds only, such as 75 or 75.5. On a phone, dragging on a small waveform is fiddly, so drag roughly and then correct the times by typing.
Keep or remove
| You want | Selection | Example |
|---|---|---|
| One part only | Keep it | A chorus, a quote, a clip for a video |
| Everything except one part | Remove it | An ad, a cough, a mistake, a long pause |
| To trim the start and end | Keep it | Select from the first word to the last |
When you remove a part from the middle, the two sides are joined directly. A short fade does not apply at the join, so pick the cut points in quiet moments.
Fades
Fade in and Fade out can be None or 0.5 to 10 seconds. Even 0.5 s takes away the click you sometimes hear when a cut starts or ends in the middle of a sound. Use 1–3 s for music that should start and end softly, 5–10 s for a long fade out at the end of a song; leave fades off for speech that should start on the first word. To only add fades to a whole file, open Fade In and Fade Out Audio, which starts with 3 s at both ends.
Tips for clean cuts
- Cut in the gaps: the waveform shows quiet parts as thin lines. Cut points there sound natural.
- Keep quality while editing: if you will edit the file again, save as WAV or FLAC. MP3, M4A and OGG are encoded again every time they are saved.
- Video sound: choosing a video saves only its sound. To cut the video itself, use Trim Video.
- Next steps: make the clip louder with the Volume Booster or join several clips with the Audio Joiner.
