LI2020 - Sound externalization in reverberant spaces

Usage

E = li2020(target_direct,template_direct,target_brir,template_brir)

Input parameters

`target`	binaural impulse response or head-related impulse response of the target sound. Matrix dimensions: time x receiver.
`template`	binaural impulse response or head-related impulse response of the template sound. Matrix dimensions: time x receiver. Note that the dimensions of target and template must be identical.

Output parameters

`E`	predicted degree of externalization

Description

Examples:

1. Anechoic signal (rendered with HRTFs or direct sound part of BRIRs) E = Li2020(tar_HRIR,tem_HRIR,[],[],'stim',stimulus,'fs',44100,'fsstim',44100,'flow',200, 'fhigh',16000, 'space',1);

2. Reverberant signal (rendered with BRIRs with unkonwn direct sound part) E = Li2020([],[],tar_BRIR,tem_BRIR,'stim',stimulus,'fs',44100,'fsstim',44100,'flow',200, 'fhigh',16000, 'space',1);

3. Reverberant signal (rendered with BRIRs with konwn direct part (HRTFs)) E = Li2020(tar_BRIR_dir,tem_BRIR_dir,tar_BRIR,tem_BRIR,'stim',stimulus,'fs',44100,'fsstim',44100,'flow',200, 'fhigh',16000, 'space',1);

The implementation is based on baumgartner2021.m
