Go to function

eurich2022_processing - Binaural processing stage of the Eurich et al. (2022) model

Usage:

[out,mpar] = eurich2022_processing(stimulus,mpar)

Input parameters:

stim Matrix containing stimulus (columns 1 and 2) and template (columns 3 and 4)
mpar

Structure with the following model parameters:

  • fs: sampling frequency of model
  • Filters_per_ERB_aud: spacing of peripheral filter central frequencies in ERB
  • flow: lower bound of gammatone filterbank
  • fhigh: higher bound of gammatone filterbank
  • gtorder: filter order of gammatone filters (hohmann2002)
  • IPDnoise: Internal noise affecting the IPD extraction
  • Dnoise: Internal noise affecting the Decision stage
  • GaussSigma: std of Gaussian across-channel smoothing
  • iKernelThresh: treshold above which a value of the Gaussian filter window is used (below := 0)
  • n_hcbins: number of bins to be used in IPD distribution computation via histcounts

Output parameters:

out Processed output structure containing ???
mpar Updated structure with model parameters
