Isolate the exact samples you need from an audio file

With Trim audio, podcasters, musicians and audio editors can prepare a track during an edit. Isolate the exact samples you need from an audio file.

Isolate the exact samples you need from an audio file. The tool is free in your browser and shows the result without asking you to create an account.

How to use

Select the audio file you want to trim; supported examples include MP3, M4A, OGG, FLAC and WAV.
Enter the start point in seconds, using the moment where the useful passage begins.
Enter the end point in seconds, or leave zero to keep everything through the end of the file.
Run the cut, listen to the extracted section and download it once the boundaries sound right.

Example

To isolate one answer in an interview, set the start just before the question and the end after the final sentence. Listen closely to the first and last seconds, because that is where a cut is most likely to clip a word or leave an awkward pause.

Limits and formats

The tool isolates one interval; it does not mix tracks, remove noise or repair damaged audio.
Start and end values are entered in seconds, so convert any minute or sample positions before typing.
Always check the edges of the result, since a precise cut can still land in the middle of a breath.
The original file stays untouched; the extracted passage is produced as a separate result.

Where processing happens

The trim runs inside your browser. The audio is read on your device, the selected interval is extracted locally, and no external transfer is involved.

Frequently asked questions

How can I find the exact start time for a cut?

Play the file in any audio player and note the time shown at the point where you want the section to begin. If the tool accepts decimals, enter the closest value, then listen and adjust by a small amount.

What happens when I set the end to zero?

A zero end value keeps everything from your chosen start point to the end of the file. That is useful when you only want to remove an introduction, a countdown or a long silent opening.

Does trimming lower the audio quality?

The cut itself does not have to add compression, but the final quality depends on the output format. Listen to the extracted passage and compare it with the source, especially if you plan further edits.
