ABSTRACT:
A buzz wave comprising n harmonic components having a flat spectrum envelope is generated according to a relatively simple algebraic expression which can be digitally computed by an arithmetic operation. Modifying harmonic components corresponding to the harmonic components to be emphasized or suppressed are also generated. The buzz wave and the modifying components are added or subtracted to form a desired musical tone signal.
