Key facts
Threshold defines how quiet a section must be.
Minimum duration prevents tiny gaps from being cut.
Background noise can keep a section above threshold.
Room tone often sounds more natural than absolute digital silence.
Practical decisions
- Start with a low threshold and longer duration.
- Review every cut when speech intelligibility matters.
Measure the source before changing it. Codec, container, duration, channels, and intended playback environment are more useful than choosing a setting from its label alone.
