Leading / Trailing Silence Detector

Detect head and tail silence and long internal gaps in an audio file against a dBFS threshold — essential before broadcast and podcast delivery.

Silence is detected below −60 dBFS. Broadcast deliverables usually require a fixed amount of head/tail (e.g. 1–2 s of black/silence), while podcast and music platforms want minimal dead air at the start so playback feels instant. Internal gaps of 1 s or more are flagged so you can catch dropouts or unintended pauses.
