Variable Delay Line Interpolation – DSP and Plugin Development Forum

Hiya guys, first post on here. I’m currently implementing some effects with variable delay lines (simple flanger and chorus), and it’s my understanding that it’s a good idea to use some sort of interpolation of my delay parameter (in my case it’s just a sine wave LFO), instead of just rounding the value to the nearest integer. It seems to me like no matter what, the delay parameter will need to be stairstepped, and I’m fuzzy on how the interpolation helps in this case. I’m not sure if this kind of “help” post is cool here, so sorry if I’m not in the right place!
