What people trim audio for
- Ringtones and notification sounds — keep the chorus or the most recognisable 20–30 seconds.
- Voice memos and interviews — remove the silence and handling noise at the start and end.
- Podcast and video clips — extract a quote or highlight to share on social media.
- Music practice — isolate a passage to loop in a practice app.
- Presentations — keep only the part of a track you need as background music.
Writing the times
Times use hours:minutes:seconds:
| You want | Start | End |
|---|---|---|
| Remove the first 5 seconds | 00:00:05 | (empty) |
| Keep the first 30 seconds | 00:00:00 | 00:00:30 |
| Keep 1:10 to 1:40 | 00:01:10 | 00:01:40 |
| Keep from 45 minutes to the end | 00:45:00 | (empty) |
If you’re unsure about the exact moment, leave a second of margin on each side; you can always trim again.
Tips
- Need another format afterwards? Convert the clip with the audio converter to MP3, WAV, M4A, OGG, FLAC or OPUS.
- Smaller file for sharing? Lossless WAV or FLAC clips can be turned into compact MP3s with WAV to MP3.
- The audio is in a video? Extract it first with MP4 to MP3, or cut the video directly with Trim video.
Supported formats
You can trim MP3, WAV, M4A, AAC, OGG, FLAC, OPUS, WMA, AIFF and AMR files, up to 1 GB. That covers music files, phone voice memos, recorder exports and old phone recordings alike.
Common problems
- The cut is a fraction of a second off. Leave a little margin and trim again if needed; a waveform editor like Audacity is better for sample-accurate edits.
- There’s a click at the start or end. Cutting in the middle of a sound can produce a click, since no fade is added. Move the cut point to a quieter moment.
