KELVASA2015_CALIBRATEMAPPING - Produces necessary mappings for localization model
Usage
[mappingData] = kelvasa2015_calibratemapping(varargin)
Input parameters
| varargin | structure with all parameters required for model. If this is not included, default paramters are loaded. |
Description
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.
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 |
