calculating the binaural cross-correlogram of a sound. The toolbox incorporates functions for: signal generation (e.g., bandpass noise, pure tone, complex tone, Huggins pitch) plotting and playing of signals calculation & post-processing of the correlogram frequency or delay weightings calculation of centroid or peak locations.
