The synthesis of rich audio spectra requires usually complex source waveforms, a large number of simple source components, or increased algorithmic complexity. This paper describes an implementation, which shows that simple elementary bitwise logical operations (OR, AND, XOR) possess power to produce such spectra. Applying these operations to two sinusoidal audio oscillators produced wide variety of new harmonically related sonic material. The synthesis method is efficient to implement and easily controllable, but it is not generally band-limited.
