Usage

[mappingData] = kelvasa2015_calibratemapping(varargin)

Input parameters

The output structure "mappingData" has the following fields:

calibHRTFsig :

NxMxS matrix of signal levels in which N is the range of azimuthal angles overwhich the signal was computed, M is the number of time samples,and S are audio channels.

calSpikeDiffPerNeuronPerAzi :

NxMxS matrix of chan2 - chan1 spike rate differences in spikes/sec in which N is the range of azimuthal angles overwhich the signal was computed, M is the number of simulated AN fibers, and S is the number of time bins.

calSpikeRatePerNeuronPerLevel:

NxM matrix of spike rates in spikes/sec in which N is a range of signal levels in dB SPL and M is the number of simulated AN fibers

calParameters :

structure of model paramters used in processing calibration stimulus

kelvasa2015_calibratemapping(varargin) processes a user specified calibration wavfile 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 & Dietz(2015)) and can therefore take several hours to process.
