REIJNIERS2014_FEATUREEXTRACTION - - extract HRTF using gammatone frequency bands and ITDs from SOFA object

Usage:

[template, target] = reijniers2014_featureextraction(SOFAobj)

Input parameters:

SOFAtemplate

Struct in SOFA format with HRTFs

Output parameters:

`template`	template struct with spectral components
`target`	template struct with spectral components

Description:

reijniers2014_featureextraction(...) computes temporally integrated spectral magnitude profiles and itd.

reijniers2014_featureextraction accepts the following optional parameters:

`'source_ir',source_ir`
	Set the sound source's impulse reponse. Default value a broadband sound source with 0dB amplitude.
`'fs',fs`	Set the sampling rate to fs. Default value takes the fs of SOFA template object.
`'fb_ch',fb_ch`	Set the number of channels for the gammatone filterbank to fb_ch. Default value is 30.
`'fb_low',fb_low`	Set the lowest frequency in the filterbank to fb_low. Default value is 300 Hz.
`'fb_high',fb_high`	Set the highest frequency in the filterbank to fhigh. Default value is 15000 Hz.
`'ir_pad',len`	Define the padding length for the impulse responses before being convolved with gammatone filters. Default value is 0.05 s.
`'targ_az',targ_az`	Set the azimuth of a set of sound sources to targ_el. It can be a scalar or a column vector Default value is []: all target azimuths are used. Must have the same size of targ_el.
`'targ_el',targ_el`	Set the elevation of a set of sound sources to targ_el. It can be a scalar or a column vector Default value is []: all target elevations are used. Must have the same size of targ_az.
