Compressor

The Pitch compressor reduces abrupt local reversals in the rendered pitch line while retaining smaller movements below its detection threshold. It acts only on voiced pitch and appears in Pitch mode.

Amount (%)

Property	Value
Key	amount
Type	Number
Range	0–100%
Default	100%
Step	1%
Neutral	0%

When a pitch reversal exceeds Detect floor, Amount determines how strongly the reversal is pulled toward its local pitch context. At 0%, the compressor is off. Higher values produce stronger correction; 100% permits the full response defined by the two detection thresholds.

Detect floor (cents)

Property	Value
Key	floorCents
Type	Number
Range	0–80 cents
Default	25 cents
Step	1 cent

Pitch curvature below this value is ignored. Lower values allow the compressor to react to smaller movement. Higher values preserve more small-scale motion, including subtle vibrato, but may leave mild overshoot unchanged.

Full pull (cents)

Property	Value
Key	fullCents
Type	Number
Range	20–200 cents
Default	100 cents
Step	1 cent

Curvature at or above this value receives the full selected Amount. Increasing the value reserves full correction for larger reversals. Decreasing it makes the compressor reach full strength sooner. Keep it above Detect floor so the partial-response region remains meaningful.

Median radius (frames)

Property	Value
Key	windowFrames
Type	Integer
Range	1–12 frames
Default	4 frames
Step	1 frame
Unit	10 ms render frames on each side

This parameter selects how much neighboring voiced pitch contributes to the local context. A small radius follows short details closely. A larger radius uses a broader context and can correct wider disturbances, but may soften intentional short movement.

Adjustment guide

If ordinary vibrato is being reduced, raise Detect floor before lowering Amount. If isolated sharp reversals remain, lower Full pull or increase Amount. Change Median radius only when the unwanted movement is visibly wider or narrower than the current correction region.
