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.
