Trim an audio file to the part you want by setting a start and end time, and save the clip as MP3, Opus or WAV.

Files and content stay on this device. Aggregate action counts are sent only with your separate consent. MP3/Opus re-encoding loses original tags and may increase size. WAV is PCM. 32 MB/file, 120 seconds total, mono/stereo; 5 files for ordered concatenation. Speed changes pitch.
Cut audio
- Prepare the input
Choose a supported audio file and set the start and end in seconds. The end must come after the start and fall within the recording. Select MP3, Opus or PCM WAV. The section you keep must be at least 0.1 seconds long.
- Try the worked example
In a 10-second recording, start 2 and end 5 keep the three-second section from 2 through 5 seconds. For PCM WAV, the boundaries are rounded to source samples. Lossy exports may include codec padding.
- Check and save
Play the beginning and the end of the saved file, not just the preview. Keep the original in case you want to edit it again; the output doesn't carry over the source tags. Changing the range or resetting makes an older result invalid, so download only the result for the current settings.
Questions
Why is my range rejected?
Negative times, an end beyond the end of the recording, or a section to keep that is shorter than 0.1 seconds are not allowed. Use decimal seconds and check the source duration that was detected.
Will the cut add fades or preserve the MP3 packets?
The tool doesn't promise fades or copying of MP3 packets. The PCM section you select is encoded into the format you choose. That can change the sound of lossy audio and its metadata, even when the timing you asked for is correct.
Which format should I verify for sample timing?
PCM WAV exposes the samples that are kept directly. MP3 and Opus may have codec delay or padding, so compare the decoded audio and the content that matters instead of assuming the container’s duration equals the exact sample interval.
