Suppose we have 2 (or more) musical notes, played with some kind
of standard musical-instrument onset. Let’s use, say, piano, guitar, and maybe
a woodwind. What is the analytic result (looking at the analytic envelopes
of the signals) in terms of time offset (or not) that results in the notes
being perceived as exactly simultaneous? First, with notes nearby (to get dL’s) and then with widely
spread notes (in frequency, not time), to get a sense of how the various
bandwidths of the cochlear filtering and the bandwidth of the instrument play
off against each other. Interestingly I’m not actually aware of any clear results of
this sort, although they may exist, I don’t know of them. Has anyone heard of such a thing? jj __________________________ James
