Audio Cutter
Remove an unwanted part from an audio recording or song and join the rest seamlessly. MP3, WAV, M4A, OGG and FLAC. Runs in your browser.
Take out the part of a recording you don't want — a stumble in a podcast, an advert in a radio recording, a long silence in a lecture, a cough in a voice memo — and keep the rest as one file. Open an audio file, play it and mark where the unwanted part starts and ends, and the Audio Cutter removes it and joins the parts before and after.
The join is seamless: a fade of just 15 milliseconds on each side of the cut, too short to hear, removes the click that a hard cut would make. Save the result as MP3, M4A (AAC), OGG (Opus) or WAV. The cutter opens MP3, WAV, M4A, AAC, OGG, Opus and FLAC files and the sound of videos, and everything happens in your browser.
How to use Audio Cutter
- Choose or drop an audio file (or a video).
- Play it and set Remove from and Remove until around the unwanted part.
- Choose the format and quality.
- Press Cut out this part and download the result.
Features
- Removes a part from the middle, start or end.
- Seamless join without a click (15 ms fades at the cut).
- Exact to the sample; the rest of the audio is untouched in timing.
- Opens MP3, WAV, M4A, AAC, OGG, Opus, FLAC and the sound of videos.
- Saves as MP3, M4A (AAC), OGG (Opus) or WAV.
- Runs in your browser: no upload, no account.
Cutter, trimmer or merger?
All three audio tools work in your browser with the same formats; pick the one for your job.
| You want to | Tool |
|---|---|
| Remove one part and keep the rest | Audio Cutter |
| Keep one part and drop the rest (ringtones, clips) | Audio Trimmer |
| Join several files into one | Audio Merger |
| Change the format of whole files | Audio Converter |
Finding the exact spot
Play the recording and pause just before the part to remove, then press Use current position next to Remove from. Continue to just after the part and set Remove until the same way. You can also type times like 12:30 or 750.5, to a tenth of a second. The note tells you how much is removed and how long the result will be. Leave a little natural pause on each side of the cut so speech doesn't sound rushed. To remove several parts, cut one, then open the result and cut the next.
Why there is no click
A sound wave cut at an arbitrary point usually jumps from one level to another where the two parts meet, which you hear as a click or pop. The cutter fades the end of the first part and the start of the second over 15 milliseconds each — far too short to notice as a fade — so the wave meets smoothly. The timing of everything else stays exactly as it was.
Common jobs
Podcasts and interviews: remove a false start, a long pause or an off-topic tangent, then cut the next one from the result. Radio and stream recordings: drop the adverts between songs. Lectures and meetings: take out the minutes before the speaker starts or a break in the middle. Music: remove a spoken intro or a hidden track separated by silence. For each job, play around the part first and leave a short natural gap so the join sounds like it was always there.
Formats, quality and privacy
MP3 at 192 kbps is a good default; choose WAV to keep the result uncompressed for further editing, M4A for Apple devices, or OGG Opus for the smallest files at high quality. When the original is already compressed, re-encoding at a high bitrate keeps any loss inaudible. Your audio is decoded and encoded on your device — nothing is uploaded — and files are checked by their content, so a renamed document is refused.
Frequently asked questions
How do I cut out part of an MP3?
Open the MP3, set Remove from and Remove until around the part, and press Cut out this part.
Will there be a click where I cut?
No. A 15-millisecond fade on each side of the cut joins the parts smoothly.
Can I remove several parts?
Yes: cut one part, then open the result and cut the next.
Does cutting reduce quality?
The audio is re-encoded once. At 192 kbps or as WAV the difference is inaudible.
Is my audio uploaded?
No. Everything happens in your browser.
Can I cut the sound of a video?
Yes, the cutter works on the sound of MP4, MOV and WebM videos and saves an audio file. To cut the video itself, use the Video Cutter.
Which formats can I save?
MP3, M4A (AAC), OGG (Opus) and WAV.
