wavefold_antideriv()

float sbl::dsp::comp::wavefold_antideriv ( float  x )

inline

First antiderivative of the wavefold triangle-wave function (F1).

The fold function f(x) on its fundamental period [-1, 3): [-1, 1): f(x) = x (slope +1) [ 1, 3): f(x) = 2 - x (slope -1)

F1(x), continuous and periodic (period 4): [-1, 1): F1(x) = x²/2 + 1 [ 1, 3): F1(x) = 2x - x²/2

wavefold_antideriv2()

float sbl::dsp::comp::wavefold_antideriv2 ( float  x )

inline

Second antiderivative of the wavefold triangle-wave function (F2).

F2(x) = integral of F1(x) from 0 to x. On the fundamental period [-1, 3): [-1, 1): F2(x) = x³/6 + x [ 1, 3): F2(x) = x² - x³/6 + 1/3

F1 has nonzero mean (3/2) over one period, so F2 grows by 6 per period. For arbitrary x: F2(x) = F2_core(x_reduced) + 6 * periods.
