#X text 36 113 Foldover occurs when you synthesize frequencies greater than the Nyquist frequency (half the sample rate). In this example \, the fundamental only reaches 1549 \, 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 1549 was chosen to make the beating effect especially strong if you're running at a sample rate of 48000 (the default one.);
