Trouble Implementing Huggins Binaural Pitch
I just glanced at a paper on this subject, and it appears that you should be introducing an inter-aural 0-to-2PI phase shift over a very narrow frequency range, rather than offsetting one signal by T. I can imagine a variety of ways to create the phase-modified noise signal, included filtering a noise signal with a high-Q 2nd-order allpass filter, or by directly creating two noise signals by summing randomly-phased sinusoids, and directly imposing the desired phase(Left)-phase(right) condition by setting the phases of the 2 arrays appropriately.
