Auto-Cut Dead Air From Any Recording

Adjustable Threshold
Choose how quiet (in dB) a section has to be before it's cut. Defaults tuned for spoken voice.
Minimum Silence Length
Set how long a pause must last to count as silence — keep natural breaths, cut dead air.

Non-silent parts are stitched seamlessly so the final file plays back at normal pace, just shorter.
