How to remove silence from audio
- Drop your recording in — the waveform appears so you can see where the gaps are.
- Adjust the silence threshold, minimum gap length and padding; cut regions are tinted live on the waveform.
- Check the stats line — it shows how many silences were found and the new duration.
- Press Apply, preview the tighter result, then download MP3 or WAV.
This silence remover finds the dead air in a recording and cuts it for you. It scans the file with a short-window loudness envelope, flags every stretch that sits below your threshold for longer than the minimum gap, and removes those pauses while leaving a little padding so speech keeps its natural rhythm. It is made for podcasters, voiceover artists and video creators who want to tighten pacing without scrubbing through a timeline by hand. The kept sections are crossfaded together so the cuts are inaudible, and the waveform preview tints exactly what will be removed before you commit. As with every SoundForge tool, the audio is processed locally and never uploaded.
FAQ
How does the silence remover decide what to cut?
It builds a loudness envelope of the file in short windows and marks any stretch that stays below your dBFS threshold for longer than the minimum gap you set. Those stretches are removed, while a padding setting leaves a little breathing room around each kept phrase so speech does not get clipped.
What threshold and minimum duration should I start with?
The defaults of -40 dBFS and 0.3 seconds work well for clean spoken-word recordings. If background noise is being kept, raise the threshold toward -30 dBFS; if natural pauses are being cut too aggressively, increase the minimum duration so only longer gaps are removed.
Will removing silence cause clicks or chopped words?
The kept sections are joined with a few-millisecond crossfade, which smooths the joins so you do not hear clicks at each cut. The padding control also leaves room around speech, so words keep their natural starts and ends instead of being trimmed mid-syllable.
Is this good for podcasts and voiceovers?
Yes — it is built for exactly that. Removing dead air and long pauses tightens the pacing of an interview, a solo episode or a narration track in seconds, and because everything runs in your browser your raw recording is never uploaded anywhere.
