Trim Audio keeps one stretch of a recording and drops the rest: the chorus of a song, the one answer you need from a long voice message, a clean clip from an interview. You type the start and end time in seconds, and the part in between is saved as a new MP3.
Everything runs in your browser with ffmpeg, so the file is not uploaded. The cut is precise to a tenth of a second, but it is a single cut — the tool cannot remove a part from the middle, join clips or add fades. Whatever the input format, the result is re-encoded as an MP3.
How to use
Choose the audio file and play it in the preview to find where your part starts and ends.
Enter the start and end time in seconds — 1:30 is 90, and tenths of a second are allowed.
Run the trim, listen to the clip, and download the MP3.
FAQ
How do I enter minutes?
Convert them to seconds: multiply the minutes by 60 and add the seconds, so 2:15 becomes 135. Tenths of a second are allowed too, which helps when a word starts right on the edge.
Can I cut out a section in the middle?
Not in one step. The tool keeps one continuous section between a start and an end. To drop something from the middle, trim the two halves separately and join them in an audio editor.
Why is the result an MP3 when my file was a WAV?
The trimmed part is always saved as MP3 so it is small and plays everywhere. If you need WAV or FLAC, run the clip through Convert Audio afterwards — it will then sound like the MP3, not like the original WAV.
Can I make a ringtone with it?
For Android, yes — Android phones accept an MP3 as a ringtone. iPhones need an M4R file, which this tool does not produce.
