HASSAGER2016 - Sound externalization based on interaural level differences

Usage

Pext = hassager2016(target,template)

Input parameters

target binaural signal for target sound(s). matrix dimensions: time x left/right.
template binaural reference signal. matrix dimensions: time x left/right.

Output parameters

Pext predicted degree of externalization

Description

Optional input parameters:

'JND',jnd ILD JND used as minimum limit for evaluation of ILD devations. Default is 1.5 [dB].
'c1',c1 Gain of ILD-deviation-to-externalization mapping function (decaying exponential) acc. to Eq. (14). Default is 3.78.
'c2',c2 Intercept of mapping function (Eq. (14)). Default is 1.
'z1',z1 Scaling parameter of mapping function (Eq. (14)). Default is 0.99.
'flow',flow Lowest frequency considered in auditory filterbank. Default is 50 [Hz].

This model calculates the externalization based on interaural level differences.
