Band Pass Filter?

It is possible to apply a frequencies filter on a numeric value? Perhaps using some FFT node, but seems it works only on audio signal. :/

Actually I need a Low-Pass filter (my value is too noisy, I’d like to stabilize it), and I’m sure there are some nodes I can use. But I cannot find it!


all filters like Damper (Animation), LinearFilter (Animation) or Newton (Animation) are low pass filters. a classic IIR low pass filter can be found here: kalle.modules.animation

thanks :D… no text …

or a little different approach
