WaveSmoother class

Post by boonier »

Hi, I can't seem to get any specific info on what this does, is it some kind of interpolation? or a lookup table?

thanks

If I'm recalling correctly, it's a buffer-averaging filter.

So it's a way to remove noise from a signal?

Partly, I suppose, but I think its main purpose is to take the kinks out of CV signals, rather than function as an audio-rate filter. I doubt it would be a very good LP audio filter. But if you need one of those, there are functions to do that in the SDK, as well. To really take noise out of an audio signal would require some sort of upsampling/downsampling along with the filter, so the signal's noise would be shifted to a part of the frequency spectrum you don't care about before being filtered out. That's the basis of what is often called oversampling; it's really a form of resampling.
