When to trim audio
Trimming is useful to remove silence or noise at the start and end of a recording, keep one answer from a long interview, cut a song excerpt for a presentation or video, or create a short sound for a notification.
A short fade in and out makes a cut sound natural instead of starting or stopping abruptly.

Frequently asked questions
Is the cut precise?
Yes, audio is cut to within a fraction of a second of the times you set.
Will trimming reduce the quality?
WAV and FLAC stay lossless. MP3 and M4A are re-encoded at a high quality setting, so any difference is very hard to hear.
Can I remove a section from the middle?
Not yet. You can trim the part before and the part after separately.
Is my file uploaded?
No. Trimming runs in your browser on your device.
