When you look at Delay1 through 5 in MONO mode in Spectrogram you see peaks and nulls in the frequency response. Spectrogram is only able to show the magnitude and not the phase of signals, so from what was learned from AFX = Bin we saw that the result of adding L + R as vectors can result in cancellation.
Similarly in Delay1 through 5 we are seeing the L and R noise signals adding together and cancelling each other out at regular intervals -- resulting in nulls in the frequency response. The *spacing* between the nulls can tell us something. I measured the spacing as follows: Delay1 : 500 Hz Delay5 : 100 Hz The nulls are caused by two signals, L and R, at the same frequency but shifted in time, and as they combine their vector sum causes the nulls. The time delay between L and R is easy to calculate based on our measurements: Delay1 = 1/500 = 2 msec Delay5 = 1/100 = 10 msec That's my best guess as to the actual delay values.
