357 bpm/60 = 5.95 bps. This is still way in the sub-audio range. You would have to effectively almost quadruple the figure in order to get into the audio range of 20-23 Hz. (Depending on the human), i.e. a drum sample or repetitive sound would have to have a frequency of 20Hz-23Hz (Or 1200-1380 bpm) in order to be heard as a single tone. I'm sure many a Jazz drummer does 357 or more on the snare, although I've never counted. Regards, Christophe P.S. Interestingly enough the figure of 20-23 Hz seems to be the breakpoint where the brain ceases to differentiate between singular events and 'chooses' to amalgamate them. This is why movie frames must be shown at, or faster than this Freq. Experiments with touch have even been devised where an equal pressure applied to the skin at less than 23Hz are perceived as being seperate events. While at higher frequencies they are perceived as a constant pressure, as though there were no movement at all. A snails perceptual freq. runs at about 4 Hz. No joke. --------------------------------------------------------------------- To unsubscribe, e-mail: idm-unsubscribe@hyperreal.org For additional commands, e-mail: idm-help@hyperreal.org
