signal.PitchDetectionHarm.Interface.HarmonicInstSumParms
dsp-collection / signal/PitchDetectionHarm / HarmonicInstSumParms
Defined in: signal/PitchDetectionHarm.ts:63
Secondary parameters for harmonicInstSum().
amplitudeCompressionExponent: number;Defined in: signal/PitchDetectionHarm.ts:21
Exponent for the common compression of all harmonic amplitudes.
HarmonicSumParms.amplitudeCompressionExponent
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: 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.
HarmonicSumParms.harmonicsDeclineExponent
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.
HarmonicSumParms.harmonicsDeclineRate
peakWidthFactor: number;Defined in: signal/PitchDetectionHarm.ts:76
Relative peak width factor. Used for peak shaping of a harmonic amplitude, depending on the deviation from the instantaneous frequency. Specifies the peak width relative to F0.
relWindowWidth: number;Defined in: signal/PitchDetectionHarm.ts:53
Window width, relative to the wavelength of the fundamental frequency. Must be an integer.
HarmonicSumParms.relWindowWidth
shiftFactor: number;Defined in: signal/PitchDetectionHarm.ts:69
Shift factor, relative to the wavelength of the frequency. Used for measuring the phase delta for computing the instantaneous frequency.
windowFunction:
| WindowFunction
| undefined;Defined in: signal/PitchDetectionHarm.ts:58
A window function or undefined for no windowing (i.e. for using a rectangular window).
