Properties

deadbandFrac: number

Deadband threshold in semitones (fractional MIDI units) used to suppress flicker.

holdAfterSilenceMs: number

Duration of continuous “silence” required to be considered a long silence, in milliseconds.

microSemitoneRange: number

Output clamp for micro drift, in semitones (fractional MIDI units).

minClarity: number

Minimum required pitch confidence in $[0, 1]$ (interpreted as a threshold).

minHoldMs: number

Minimum time between commits, in milliseconds.

minHz: number

Ignores detected pitch values below this frequency, in Hz.

minStableMs: number

Minimum time a candidate pitch class must persist before it can be committed, in milliseconds.

smoothingBase: number

Base smoothing factor applied to pitch tracking (dimensionless).

smoothingClarityScale: number

Additional smoothing factor scaled by clarity (dimensionless).
