Cut Audio

Trim the start and end of an audio file.

Your files never leave your device.

When to use it

Use this tool to keep just the part of an audio file you need. It is ideal for making a ringtone, clipping a quote from an interview, trimming silence from the start of a voice memo, or cutting a song down for a video or presentation. You can also add a smooth fade in or fade out.

How to use it

  1. Click Choose audio or drop a file. MP3, WAV, M4A, OGG, FLAC and more work, up to 100 MB.
  2. The waveform appears. Click anywhere on it to move the playback position.
  3. Set the Start and End times. Type them in, or play the audio and use the buttons next to each box to set them to the current position. Use Play selection to check the cut.
  4. Choose a Fade in and Fade out, from none up to 3 seconds.
  5. Under Save as, choose MP3 or WAV. For MP3, pick the MP3 quality: 128, 192 or 320 kbps.
  6. Click Cut audio, listen to the result, then click Download.

If the cut is not quite right, click Change the cut to adjust it without loading the file again.

Worked example

You want a 30-second ringtone from a song you own. Load the file and play it until the chorus starts at about 1:12. Set the start there, then set the end at 1:42. Add a 1-second fade in and a 2-second fade out so it does not start or stop suddenly. Save as MP3 at 192 kbps. The result is about 0.7 MB, small enough for any phone.

Tips

  • Use the waveform to find gaps. Quiet parts look flat, which makes it easy to find the space between sentences or songs.
  • Fine-tune with Play selection. Listen to the start and end a few times and nudge the times by a fraction of a second.
  • Fades hide rough edges. Even a 0.5-second fade stops a click when the cut lands in the middle of a sound.

Common mistakes

  • Starting the cut too tight. Leave a fraction of a second before the first word so it is not clipped.
  • Choosing WAV for sharing. WAV files are around seven times larger than 192 kbps MP3s. Use MP3 unless you need full quality.
  • Using audio you do not have rights to. Only cut and share recordings you own or have permission to use.

Frequently asked questions

Is my audio uploaded anywhere?

No. The file is decoded and cut inside your browser, and the result is saved straight to your device. Nothing is sent to a server.

Should I save as MP3 or WAV?

MP3 is much smaller and plays everywhere, so it is best for ringtones, sharing and podcasts. WAV is uncompressed and keeps every detail, which is useful if you plan to edit the clip further. A one-minute stereo WAV is about 10 MB, while a 192 kbps MP3 is about 1.4 MB.

Why is there a limit of 3 hours?

The whole recording is held in your device's memory while you edit. Very long files can use more memory than a phone or older computer has. Cut long recordings into shorter parts first.

Will cutting an MP3 lose quality?

Saving as MP3 again re-encodes the sound, which loses a tiny amount of detail. At 192 kbps or 320 kbps most people cannot hear the difference. Choose WAV if you need no further loss.

Can I cut out the middle and join the two ends?

Not in one step. This tool keeps one section. To remove a middle part, save the first part and the last part separately, then join them in an audio editor.
