Hi,
Using the source:
pd/src/d_filter.c/sigrzero_perform()
t_sample next = *in1++; t_sample coef = *in2++; *out++ = next - coef * last; last = next;pure-data/externals/cxc/delta~.c/delta_perform()
float f = *(in++); // *out++ = (f > 0 ? f : -f); *out++ = (f > x->x_last ? fabs(f - x->x_last) : -fabs(f -x->x_last)); x->x_last = f;
Oops, another nameclash: I wasn't aware of delta~ from cxc and was referring to delta~ from Cyclone. Anyway, seems they do the same in the end.
Ciao
