Remove Silence from Audio Online

Upload your audio file, adjust the silence threshold (how quiet counts as silence) and minimum duration (how long a pause must be to get cut). The tool detects and removes all matching sections. Download the trimmed result as WAV.

You control what gets removed. Set a higher threshold to only catch true silence. Set a longer minimum duration to keep short natural pauses and only remove extended dead air. Preview before downloading.

Yes. This is one of the most common use cases. Upload your podcast recording, set the threshold to catch room noise and long pauses, and download a tighter edit. Typical podcast recordings lose 10-30% of their length from silence removal.

Yes. Detected silent regions are highlighted on the waveform before you click remove. You can adjust the threshold and minimum duration to fine-tune what gets cut.

The threshold sets how quiet audio needs to be to count as silence. A lower threshold (e.g., -60 dB) only catches true silence. A higher threshold (e.g., -30 dB) also catches quiet room noise and breathing.

No limits. The tool runs locally in your browser. It handles files of any size that your device's memory supports.

Completely free. No account, no signup, no watermarks, no limits. Remove silence from as many files as you want.
