Find silences in audio

With Find silences in audio, podcasters, musicians and audio editors can prepare a track during an edit. List or remove the gaps in a recording, with your own threshold and length.

List or remove the gaps in a recording, with your own threshold and length. Use it free in your browser with no account required.

How to use

Select the recording you want to analyse, such as an interview or a voice take.
Set the silence threshold in decibels to define what counts as a gap.
Enter the minimum silence duration in seconds so short breaths are ignored.
Choose whether to list the silences or delete them, then start the analysis.
Review the list or listen to the cleaned file before downloading it, because automatic detection always benefits from a human check.

Example

After an interview, a long pause before an answer can be removed to keep the edit moving. List the silences first with a careful threshold, then delete only the gaps that exceed the minimum duration you selected.

Limits and formats

A threshold that is too high may treat a quiet breath as silence and remove a useful sound.
A threshold that is too low may leave obvious gaps in a noisy recording.
Deleting silences removes the detected intervals, so always listen to the transitions before using the result.
The tool cannot know which pause is meaningful, so review the list before cutting.

Where processing happens

The analysis and any deletion run inside your browser. The file stays on your device, and no outside transfer or account is required.

Frequently asked questions

How do I choose the right silence threshold in decibels?

Start with a moderate value, run the analysis and listen to the listed gaps. Lower the threshold if quiet breaths are being removed, or raise it if obvious silences are still passing through.

Does removing silences shorten the total audio?

Yes, every gap you delete is removed from the timeline, so the final file is shorter. Check the result by ear to make sure the remaining speech still flows naturally.

Can I detect silences without changing the file?

Yes, choose the listing option. The tool then shows the detected intervals without producing a modified audio file, so you can review them before deciding what to delete.
