takanen2013_mso - Model of the medial superior olive

Usage

output = takanen2013_mso(ipsilateral, contralateral, fs, fc, printfigs)

Input parameters

ipsilateral The ipsilateral "where" stream output from the model of the periphery
contralateral The contralateral "where" stream output from the model of the periphery
fs sampling rate
printFigs boolean value that defines whether several figures illustrating the processing steps in the model are plotted or not. As default, no figures are plotted.

Output parameters

output Spatial cues for separate narrow bandwidths

This function models the medial superior olive (MSO) by processing the output of the periphery model with the following steps:

  1. Delay and convolution is applied to the contralateral signal and the ipsilateral signal is limited and normalized.
  2. Coincidence detection between the ipsilateral and contralateral signals.
  3. Weighted and self-weighted moving average filters are applied to the outputs of the coincidence detection and contralateral signal, respectively, and the output is limited.
