SprModelSynth
extends BaseAlgorithm
in package
SprModelSynth
Inputs:
[vector_real] magnitudes - the magnitudes of the sinusoidal peaks [vector_real] frequencies - the frequencies of the sinusoidal peaks [Hz] [vector_real] phases - the phases of the sinusoidal peaks [vector_real] res - the residual frame
Outputs:
[vector_real] frame - the output audio frame of the Sinusoidal Plus Stochastic model [vector_real] sineframe - the output audio frame for sinusoidal component [vector_real] resframe - the output audio frame for stochastic component
Parameters:
fftSize: integer ∈ [1,inf) (default = 2048) the size of the output FFT frame (full spectrum size)
hopSize: integer ∈ [1,inf) (default = 512) the hop size between frames
sampleRate: real ∈ (0,inf) (default = 44100) the audio sampling rate [Hz]
Description:
This algorithm computes the sinusoidal plus residual model synthesis from SPS model analysis.
Category: Synthesis Mode: standard
