Re: [microsound] Binaural Beats

[BJM <bent@xxxxxxxxx>]

 I don't know about all the brainwave mumbo jumbo, but this little hack 
is pretty cool for making weird sound (microsound?). Thanks for the tip.

Oh, and I don't know what folks are talking about with all the 
psychological and perception stuff. Beating is certainly a physical and 
observable phenomenon. Sound is nothing more than air molecules being 
pushed and pulled. Beating occurs when two waves interfere with each 
other, causing some pushing to step on some pulling (and vice versa) and 
some pushing to add to some pushing (and vice versa). That's a dorky way 
of saying that there's some summing and cancelling and that causes 
beating. To prove it to yourself, generate the two frequencies in a 
sound editor (with a wave form display... like sound forge or peak) and 
then mix them together... voila, beautiful, egg-shaped beats.
