The Raw Byte Audio Machine allows the user to operate on a constant sawtooth wave that is calculated against the assigned sample rate and bit-depth. With each sample, the counter "t" increments by 1. Your expression is evaluated and the lowest bits become a PCM audio sample. Expressions allow for binary arithmetic like addition, subtraction, division, and modulo; and bitwise operations like AND/OR/NOT and bit shifting. With these combinations of tools, a single expression can yield tremendous musical results in complex rhythms, harmonies, and melodies, all while operating on a single sawtooth wave. Operates as a standalone app or AUv3 instrument plugin.
