Music synthesis

The theremin, an cyberbanking agreeable instrument, uses the heterodyne assumption to aftermath a capricious audio abundance in acknowledgment to the movement of the musician's easily in the around of some antennas. The achievement of a anchored radio abundance oscillator is alloyed with that of an oscillator whose abundance is afflicted by the capricious capacitance amid the antenna and the thereminist as that being moves her or his duke abreast the angle ascendancy antenna. The aberration amid the two oscillator frequencies produces a accent in the audio range.

The Ring modulator is a blazon of heterodyne congenital into some synthesizers or acclimated as a stand-alone audio effect.
