hello. I heard an interesting sound today--the far off low thud- thud-thud of a helicoptor. A little bit unusually, however, its sound was distinctly...
... Not unusual at all! Helicopter blades perform a periodic motion (around an axis, over and over again), so their spectrum must be a harmonic one. That...
Can harmonic entropy help us predict the perceived fundamental pitch of timbres with inharmonic spectra? (For example, unruly piano strings...) What other...
... Well, it can tell you how salient each potential fundamental pitch is, since each potential fundamental pitch implies a particular ratio- interpretation...

Hello. I've been wondering.... When Banade lists a series of 'heterodyne' or comb tones elements such as "3P, 2P+Q...", is the "3P" component by itelf a...
... You can think of the 3P as P+P+P -- it's simply a cubic combinational tone like just like P+P+Q (=2P+Q). ... (3P- ... That's a combinational tone, but not...
Hello Paul, and anyone else who is around -- I was wondering...concerning that familiar chart of harmonic number vs. amplitude, with each sucessive harmonic...

In the case of equal temperament, the beating will quickly cycle you through all relative phases, so the amplitudes over time will average out to being equal. ...
Hello group. I read the statement below, and was wondering if you scholars would be kind enough to say whether it is true, and if so, where I could learn more...
... It depends in what sense you mean "add" and "multiply". It can't be in one and the same sense. ... This seems to be *least* true for phi and *most* true...

Hi Kelly, I think Paul answered the points on phi pretty much as I would have, so I won't repeat any of that. But I'm intrigued by your synaesthetic experience...

Kelly, You're actually talking o some fairly subtle sounds - for example, balloons rubbing together - and some that are very difficult to record realistically...
Hi Kelly, True synaesthesia, as I understand it, consists in perceiving things _as if_ through another sense; there's no question of forcing anything. ...
