Remove Silence from Audio
Automatically strip silent gaps from your audio. Ideal for podcasts, recordings and interviews. Adjust threshold and minimum duration to protect natural speech pauses.
Audio below this level is treated as silence. -40 dBFS is a safe default for most recordings.
Only silence longer than this is removed. Shorter pauses (e.g. natural breathing) are kept.
A small amount of silence to keep at the edges of speech sections to avoid cutting words.

How to use
- 1.Set threshold — -40 dBFS is a safe default. Increase (e.g. -30 dBFS) to remove more, decrease (e.g. -50 dBFS) to be more conservative.
- 2.Set minimum duration — Only silence longer than this value is removed. 0.5s prevents removing natural brief pauses in speech.
- 3.Set padding — Keeps a small buffer of silence around speech to avoid clipping words at their edges.
- 4.Upload and process — Drop your audio file, click Remove silence, and download the result.

FAQ
Will this remove speech?
If the threshold is set too high or minimum duration too low, quiet speech may be incorrectly removed. Use conservative settings (-40 dBFS, 0.5s minimum) for speech recordings and test on a short clip first.
What is the silence threshold?
Audio samples below this dBFS level are considered silence. -40 dBFS means anything quieter than 1% of maximum digital volume is treated as silence.
Why keep padding?
Words often start and end with very quiet sounds (consonants, breath). A small padding (0.1s) prevents the tool from clipping the beginning and end of words.
