kelvasa2015_calibratemapping
Produces necessary mappings for kelvasa2015

Usage:

mappingData = kelvasa2015_calibratemapping(varargin);

Input parameters:

varargin

All parameters required for model. If this is not included, default parameters are loaded.

Output parameters:

mappingData

Calculated mapping data, including the following fields:

calibHRTFsig: Signal levels. Size: (N x M x S) with N being the range of azimuthal angles overwhich the signal was computed, M being the number of time samples, and S being the number of audio channels.
calSpikeDiffPerNeuronPerAzi: Matrix of chan2-chan1 spike rate differences (in spikes/s). Size: (N x A x B) with N being the range of azimuthal angles over which the signal was computed, A being the number of simulated AN fibers, and B is the number of time bins.
calSpikeRatePerNeuronPerLevel: Matrix of spike rates (in spikes/s). Size: (L x A) with L being the range of signal SPLs (in dB) and A being the number of simulated AN fibers.
calParameters: Structure of model paramters used in processing calibration stimulus.

Description:

kelvasa2015_calibratemapping(varargin) processes a user-specified calibration sound file and extracts the necessary data required to map simulated bilateral neural outputs onto a predicted azimuthal angle. This function computes data required by all three localization models described in Kelvasa and Dietz (2015) and can therefore take several hours to process.
