Frequently asked questions
Will it cut into the speech?
The threshold decides. At -50 dB only near-silence is removed; if quiet words disappear, choose the gentler -60 dB setting.
Can I use this on a podcast recording?
Yes. "Every pause" is made for that: long gaps shrink to a quarter second and the recording keeps its rhythm.
Is this private?
Yes. The processing happens entirely in your browser. Your files are never uploaded.
