Hi all, Surely there must be some upper time limit over which the computation of the first moment of the spectrum has any meaningful value to the psychoacoustician. For example, time-reversed versions of many stimuli are perceptually very different, yet have identical first moments if computed over the full duration of the stimuli. Seems like one would have to compute a running first moment over time to differentiate such stimuli on the basis of their first moments. Cheers, Daniel J.
