LECLERE2015 - Compute the binaural useful-to-detrimental ratio for a reverberated target

Usage

[twoears_benefit, weighted_bmld, weighted_better_ear] = leclere2015(target_in,int_in,fs)

Input parameters

target_in target
int_in interferer
fs sampling frequency [Hz]

Output parameters

twoears_benefit useful-to-detrimental ratio
weighted_bmld weighted binaural masking level difference
weighted_better_ear
 weighted better ear advantage

Description

leclere2015 computed the binaural useful-to-detrimental ratio for a reverberated target and multiple stationary noise interferers. The early and late parts of the target BRIR are separated, the early part constitutes the useful signal while the late part is concatenated with the interferer BRIRs to constitute the detrimental signal.
