Remove part of an audio file
Drop an MP3, M4A, or WAV, mark the parts you want gone on its waveform, and download the rest joined up, in the same format. Take out one part or several at once, such as every cough in a recorded talk.
The boxed sections are taken out. Drag a box to move it, or its edges to resize it, or type its times. Press anywhere else to play from there.
The result appears here once a file is open.
How to use it#
- Drop a sound file onto the box above, or click it to choose one.
- Play to where a part you want gone begins, then press Add a section. Drag the edges of its box on the waveform, drag the box to move it, or type From and To.
- Add as many sections as you need. Press a box on the waveform, or pick it in the list, to change it, and remove one with its cross.
- Play the result in the preview, then download it.
Several parts in one go#
A recorded talk with three coughs, a podcast with two ad breaks, or a voice note with a false start and a long silence all need more than one cut. Mark each part as a section and the page takes them all out together and joins what is left, so there is no need to cut, download, and open the file again for each one.
Sections that overlap or touch are taken out as one, so marking the same stretch twice does no harm. The page refuses only a set of sections that leaves nothing behind.
Joins without a click#
Two stretches of sound put end to end rarely meet at the same level, and the jump between them is heard as a click. So each join rises and falls over a hundredth of a second, too short to hear as a fade and long enough to smooth the jump.
That means an MP3 or an M4A is encoded again, at the bitrate it was made at, which costs a little quality that is very hard to hear. A WAV is written out sample for sample at its own bit depth and loses nothing. A FLAC cannot be cut here, because no browser can write FLAC again; make it an MP3 with FLAC to MP3 first.
A browser that cannot write AAC joins an M4A as it was, without the rise and fall, and the page's Sound line reads Copied as it was. There, a cut placed in a pause matters more.
Keeping one part instead#
If you want a single part of the file, such as a chorus for a ringtone, the audio cutter keeps it and drops everything else, and can fade it in and out. This page is for the opposite: keeping almost everything and taking out the parts you do not want.
Frequently asked questions#
How do I cut out the middle of an MP3?
#
Drop the MP3 here, play to where the part you want gone begins, and press Add a section. Drag its right edge to where the part ends, or type the time in To. The rest is joined up into a new MP3 to download.
Can I remove more than one part?
#
Yes. Add a section for each part you want gone, and all of them are taken out together. The list of sections shows each one, and the cross beside a section removes it from the list.
Will I hear where the parts were joined?
#
Usually not. Each join rises and falls over a hundredth of a second so it does not click, though a cut in the middle of a word or a note will still sound like one. Cutting in a pause, where the waveform is flat, gives the cleanest join.
Does it lose quality?
#
An MP3 or an M4A is encoded again at the bitrate it was made at, which is very hard to hear. The result can still come out smaller than the parts it keeps, because the encoder spends fewer bits where the sound is simple. A WAV loses nothing.
How do I cut part of a voice memo on an iPhone?
#
Voice Memos saves recordings as M4A, which works here. In the app, tap the memo, tap the three dots, and choose Save to Files. Then open this page in Safari, tap the box, and pick the memo from Files. The cut memo is saved to Files too, under Recents. It needs a current iOS: an older Safari, such as Safari 17, cannot read the sound a piece at a time, and the page says so.
Can I take a part out of a video?
#
Yes, on cut video, which takes one or more sections out of an MP4, MOV, WebM, or MKV and joins the rest, marked the same way.
Is my file uploaded?
#
No. The file is read and cut inside this browser tab, and the result is handed straight to your downloads. Nothing is sent to a server.
