Pro Audio Tips
How to Get Natural Pacing Without Awkward Cuts
Smart Truncate vs Full Cut
Deleting 100% of silence can make interviews sound like an unnatural jump-cut rush. "Smart Truncate" shortens dead pauses to a comfortable 300ms room-tone gap, giving you tight pacing with authentic flow.
Top & Tail Edge-Trim
Need to strip waiting time before someone starts speaking and dead air after they wrap up? Top & Tail trims only the outer boundaries with 20ms anti-pop cosine fades, leaving interior speech cadence 100% untouched.
Word Safety Buffer (Padding)
Human speech naturally decays into quiet consonant tails ("s", "t", breath drops). Keeping a 100ms–150ms safety buffer around speech regions guarantees words are never abruptly chopped off.
Fixing AC Hum Before Trimming
If your track has an audible air conditioner or fan drone, raise the threshold slider to −35 dB, or run our AI Noise Remover first to ensure clean pause detection.

Technology
Hardware-Accelerated In-Browser Silence Detection
Unlike cloud-based tools that require uploading gigabytes of footage and waiting in server queues, this tool leverages your device's multi-core hardware via the Web Audio API.
It performs continuous 20ms Root-Mean-Square (RMS) windowing to map speech envelopes against your chosen dB threshold. When silence boundaries are detected, speech regions are joined using smooth linear micro-fades to guarantee zero clicks or unnatural audio artifacts.
Running 100% locally on your computer or phone, your media remains strictly private, zero data is uploaded, and processing finishes in seconds.
