supdeq_calcILD

% SUpDEq - Spatial Upsampling by Directional Equalization

 function ild = supdeq_calcILD( hrir )

 This function calculates the ILD (Interaural Level Difference) of a HRIR 

 Output:
 ild               - ILD of the HRIR in dB

 Input:
 hrir              - [N x 2] HRIR with N samples and 2 channels    

 Dependencies: -
