In this example +\, the fundamental only reaches 1423 \, but the tables contain high +partials. As the partials sweep upward you hear them reflect off the +Nyquist frequency. Also \, partials can come into contact with each +other causing beating. The value of 1423 was chosen to make the beating +effect especially strong \, but it's clearly audible even for a 440-Hz. +sawtooth wave \, for example.; +#X text 25 58 Use this patch sparingly... it's probably bad for your +ears.
