Frequently Asked Questions

How does the AI silence remover detect dead air and pauses?

ClipHelix utilizes high-precision Web Audio decibel analyzers to examine the audio amplitude waveform. When silence or low ambient room tone extends beyond your customizable threshold (e.g., 250ms), it marks precise split points and trims the dead air seamlessly.

Can I adjust the silence threshold sensitivity and minimum pause duration?

Yes! You can easily adjust the decibel threshold slider (-40 dB to -15 dB) and minimum pause length slider (150ms to 800ms) to customize whether you want aggressive rapid jump cuts or natural conversational pacing.

Does silence trimming desynchronize subtitles or additional audio tracks?

No. ClipHelix applies rippled timeline trimming across all synchronized tracks including video, voiceover, background music, and auto-generated subtitles simultaneously.

Is silence removal free to use in ClipHelix?

Yes! Silence and dead air removal is available directly in the free browser editor without watermarks.
