HprModelAnal extends BaseAlgorithm
in package

HprModelAnal

Inputs:

[vector_real] frame - the input frame [real] pitch - external pitch input [Hz].

Outputs:

[vector_real] frequencies - the frequencies of the sinusoidal peaks [Hz] [vector_real] magnitudes - the magnitudes of the sinusoidal peaks [vector_real] phases - the phases of the sinusoidal peaks [vector_real] res - output residual frame

Parameters:

fftSize: integer ∈ [1,inf) (default = 2048) the size of the internal FFT size (full spectrum size)

freqDevOffset: integer ∈ (0,inf) (default = 20) minimum frequency deviation at 0Hz

freqDevSlope: real ∈ (-inf,inf) (default = 0.00999999977648) slope increase of minimum frequency deviation

harmDevSlope: real ∈ (-inf,inf) (default = 0.00999999977648) slope increase of minimum frequency deviation

hopSize: integer ∈ [1,inf) (default = 512) the hop size between frames

magnitudeThreshold: real ∈ (-inf,inf) (default = 0) peaks below this given threshold are not outputted

maxFrequency: real ∈ (0,inf) (default = 5000) the maximum frequency of the range to evaluate [Hz]

maxPeaks: integer ∈ [1,inf) (default = 100) the maximum number of returned peaks

maxnSines: integer ∈ (0,inf) (default = 100) maximum number of sines per frame

minFrequency: real ∈ (0,inf) (default = 20) the minimum frequency of the range to evaluate [Hz]

nHarmonics: integer ∈ (0,inf) (default = 100) maximum number of harmonics per frame

orderBy: string ∈ {frequency,magnitude} (default = "frequency") the ordering type of the outputted peaks (ascending by frequency or descending by magnitude)

sampleRate: real ∈ (0,inf) (default = 44100) the sampling rate of the audio signal [Hz]

stocf: real ∈ (0,1] (default = 0.20000000298) decimation factor used for the stochastic approximation

Description:

This algorithm computes the harmonic plus residual model analysis.

It uses the algorithms HarmonicModelAnal and SineSubtraction .
