Frequently asked questions
Is my audio uploaded anywhere?
No. Detection and cutting run 100% in your browser. Your file never leaves your device.
How does it decide what is silence?
Anything quieter than your dB threshold, lasting longer than your minimum length, gets cut — with a small safety padding.
Can I control how aggressive it is?
Yes — threshold (−60 to −20 dB) and minimum silence (0.2–2s) sliders let you go gentle or ruthless.
What format is the download?
A gapless WAV with all detected silences removed.
