Audio trimmer

Trim an audio file in three steps

1. Choose an audio file or a video, or try the included sample.
2. Drag across the waveform over the part you want to keep, or type its start and end time. Clicking the waveform moves the playhead there.
3. Press Trim audio, listen to the preview, and download the shorter file.

What trimming is good for

Trimming is the quickest edit there is. Cut dead air from the start of a voice memo, pull one answer out of a long interview, make a ringtone from a song section, or shorten a clip to fit an upload limit. Only the part between your start and end times is kept, and nothing else is changed, so the sound of the kept section matches the original.

Setting exact times

Type times in seconds, with decimals for precision. Play the original, pause at the moment you want, and read the time from the player. Because the editor accepts tenths of a second, you can trim right at the edge of a word. If your cut lands in the middle of a loud note you may hear a small click, which a one-second fade out will smooth.

Trimming video and keeping the picture

If you choose a video, the picture and the soundtrack are cut together so they stay in sync. The result is a shorter video in MP4 or WEBM, depending on what your browser can encode. Choose audio only to save just the sound as an MP3. Very long videos use memory while they process, so trim a very large file in stages.

Private by design

The recording is decoded in your browser tab and the cut is made on your device. Nothing is uploaded to AudioClover, there is no signup, and there is no watermark. When you close the tab the file is gone.
