#X text 47 52 WARNING: PLAY THIS QUIETLY TO AVOID UNPLEASANTNESS AND POSSIBLE EAR DAMAGE., f 39;
#X text 46 99 Foldover occurs when you synthesize frequencies greater than the Nyquist frequency (half the sample rate). 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 if you're running at a sample rate of 44100 (the usual one.);
