FBSineN | SuperCollider 3.12.2 Help

Description

A non-interpolating sound generator based on the difference equations:

        x(n+1) = sin(im * y(n) + fb * x(n))
        y(n+1) = (a * y(n) + c) % 2pi

This uses a linear congruential function to drive the phase indexing of a sine wave. For im = 1, fb = 0, and a = 1 a normal sinewave results.

sclang code translation:( var im = 1, fb = 0.1, a = 1.1, c = 0.5, xi = 0.1, yi = 0.1, size = 64; plot(size.collect { xi = sin((im * yi) + (fb * xi)); yi = (a * yi + c) % 2pi; xi }); )
