StochasticModelAnal

standard mode | Synthesis category

Inputs

  • frame (vector_real) - the input frame

Outputs

  • stocenv (vector_real) - the stochastic envelope

Parameters

  • fftSize (integer ∈ [1, ∞), default = 2048) :
    the size of the internal FFT size (full spectrum size)
  • hopSize (integer ∈ [1, ∞), default = 512) :
    the hop size between frames
  • sampleRate (real ∈ (0, ∞), default = 44100) :
    the sampling rate of the audio signal [Hz]
  • stocf (real ∈ (0, 1], default = 0.2) :
    decimation factor used for the stochastic approximation

Description

This algorithm computes the stochastic model analysis. It gets the resampled spectral envelope of the stochastic component.
