Cut a recording

Trim audio online: cut a recording to the part you want

Type a start and an end in seconds and get that section back as an MP3. This free online audio trimmer keeps the recording’s own sample rate, plays the result beside the original so you can check the edit, and uploads nothing.

Trim a recording

Choose a recording WAV, AIFF, MP3 or M4A. It is read in this tab and never sent anywhere.

Start (seconds) End (seconds)

What it does with your file

Cut by the clock, exported clean

Seconds, not a dragged handle

Start and end are typed in seconds, because the number you want is usually one you already know — from a slate, a note, or the checker telling you where a problem is. Leave the end empty to keep everything after the start.

A range outside the file is refused

Asking for a section that does not exist returns nothing to download and says so, rather than handing back a silent file that looks like a successful export.

Your sample rate is kept

The export is a 192 kbps MP3 at the recording’s own sample rate, so trimming a 48 kHz master gives back 48 kHz. The exceptions are rates this encoder cannot write — anything outside 32, 44.1 and 48 kHz — which are resampled to 44.1 kHz, and the page says when it had to.

Nothing is uploaded

The recording is decoded, cut and re-encoded inside this browser tab. The tools on this site never upload your audio: every check and fix runs in this tab.

Then join the takes

The joiner puts trimmed takes together into one chapter, reconciling any parts that disagree about sample rate or channel count.

Then check it

The chapter checker measures the result against what ACX, Spotify, Google Play and Apple publish, and the noise remover handles what is left underneath.

Questions about trimming audio

How do I cut a section out of an audio file?

Choose the recording, type the start and end in seconds, and press trim. That section is decoded, cut and re-encoded as a 192 kbps MP3 at 44.1 kHz inside this browser tab, and played back beside the original so you can check the edit before downloading it.

Why does it ask for seconds instead of dragging a handle?

Because the number is usually one you already have — from a slate, a note, or a checker telling you where a problem sits. Typing 62.5 is exact; dragging to it is not. Leave the end empty to keep everything from the start onwards.

What happens if I ask for a range the file does not have?

Nothing is offered for download and the page says the range is outside the recording. Handing back a silent file that looks like a successful export is the failure that guard exists to prevent.

Does trimming re-encode the audio?

Yes. The export is a 192 kbps MP3 at the recording's own sample rate — trimming a 48 kHz master gives back 48 kHz. Only rates this encoder cannot write, meaning anything outside 32, 44.1 and 48 kHz, are resampled to 44.1, and the page says when it had to. Either way it is one generation of lossy encoding, so keep your original master.
