Properties

amplitudeCompressionExponent

amplitudeCompressionExponent: number;

Defined in: signal/PitchDetectionHarm.ts:21

Exponent for the common compression of all harmonic amplitudes.

Inherited from

HarmonicAmplitudeEvaluationParms.amplitudeCompressionExponent

---

fCutoff

fCutoff: number;

Defined in: signal/PitchDetectionHarm.ts:47

Cutoff frequency in Hz. Specifies a hard upper frequency limit up to which the harmonic amplitudes are evaluated.

---

harmonicsDeclineExponent

harmonicsDeclineExponent: number;

Defined in: signal/PitchDetectionHarm.ts:36

Hyperbolic decline exponent constant for the decline rate of the harmonic.

• 1 for harmonic decline.
• 0 for exponential decline.
• -1 for linear decline (with clipping to 0).
• Between 0 and 1 for hyperbolic decline.

harmonicsDeclineRate

harmonicsDeclineRate: number;

Defined in: signal/PitchDetectionHarm.ts:27

Base value for a decline rate depending on the order of the harmonic. Initial negative slope of the decline curve.

relWindowWidth

relWindowWidth: number;

Defined in: signal/PitchDetectionHarm.ts:53

Window width, relative to the wavelength of the fundamental frequency. Must be an integer.

---

windowFunction

windowFunction: 
  | WindowFunction
  | undefined;

Defined in: signal/PitchDetectionHarm.ts:58

A window function or undefined for no windowing (i.e. for using a rectangular window).
