k2k audio Parameters
| Parameter | Range | Default |
|---|---|---|
| Threshold (dB) | -80.0 – -20.0 | -60.0 |
| Smoothing | 0.0 – 1.0 | 0.3 |
Threshold (dB) — Magnitude threshold (in dB) below which content is considered silence, −80 to −20. Note this is the same parameter as in NoiseFloor Extractor but with a different intent: here you’re looking for silent regions in time rather than quiet content per-frame. Lower thresholds (−70 to −80 dB) catch only true silence (mostly digital silence between sections); higher (−40 to −30 dB) include quiet program-material regions like breath gaps and natural pauses.
Smoothing — How much temporal smoothing is applied to the silence detection, 0–100%. Higher values smooth out brief loud spikes within otherwise-silent regions (so brief crackles inside a silent gap don’t break up the silence detection). 30% is balanced; raise to 60–80% for cleaner silence detection on noisy material.
Additional controls
Min Duration Ms — Minimum duration in ms a silent region must last to be flagged, 10–1000. Below this threshold, brief silences are ignored. Useful for ignoring micro-gaps between musical events while catching real silent sections like song breaks, inter-phrase pauses, or recording lead-ins/outs. 100 ms is balanced for music; raise to 500+ ms for catching only longer pauses.
About Silence Extractor
Silence Extractor finds time regions where the input is below threshold and outputs them as a separate stream. The two outputs are: the silent regions (extracted — typically actually silent or near-silent) and the active program material (rejected). The most useful pattern is: pass the rejected output (program material) through heavy processing while ignoring the silent regions, then recombine — saves CPU and avoids processing nothing. Or: use the silent regions as auto-detected gaps for inserting other material (cross-spectral gating, swap-in of texture during silence, etc.). For per-band/per-frame quiet-region detection, see the Spectral Gate; for time-region silent extraction, this node is the right tool.
