# hauth2020_fftcon - Cancellation process

## Usage

[Mixsigmin, Mixsigmax, ECparams4Opt] = hauth2020_fftcon(MixsigL,MixsigR,fc,fs,sigmadelta0,Delta0,bin_inaccuracy)


## Input parameters

 MixsigL Left ear signal MixsigR Right ear signal fc center frequency of frequency channel fs sampling frequency sigmadelta0 term to calculate binaural processing inaccuracy Delta0 term to calculate binaural processing inaccuracy bin_inaccuracy flag indicating the use of (1) binaural processing inaccuracies or (0) assuming binaural processing to be deterministic

## Output parameters

 Mixsigmin EC processed signal using the minimization strategy Mixsigmax EC processed signal using the maximization strategy ECparams4Opt Structure containing EC parameters (Delay and Uncertainties)

## Description

First, left and right ear signal are transformed to frequency domain in order to calculate the cross power spectral density. By calculating the angle of the CPSD and, the frequency dependent ITD can be obtained by dividing the angle by the angular frequency. In order to obtain the final ITD value for the frequency band, an integration window derived from the absolute value of the CPSD is applied.
