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.
