Definitions for "Additive synthesis"
The process of constructing a complex sound using a series of fundamental frequencies (pure tones or sine waves). Each of the fundamental frequencies usually has its own amplitude envelope which allows independent control of each partial(harmonic). Pipe organs or Hammond organs are both instruments which are based on additive synthesis.
envelope modulation amplitude sample-and-hold
a synthesis method that builds complex waveforms by combining sine waves whose frequencies and amplitudes are independently variable.
method of producing full-color images by mixing light of the three primary color wavelengths, blue, green and red.
