BAN-1: Dynamic Smoothing Algorithm

 
BAN-1: Dynamic Smoothing Algorithm by Andrew Simper

This app note by Andrew Simper of cytomic describes an algorithm for smoothing noisy controls and lends itself nicely to digitized potentiometers or other controls that might transmit noisy signals including software GUI controls – RackAFX now has an automatic parameter smoothing option that also uses a filtering operation to smooth glitches from quick changes in the GUI controls, but it would not eliminate the kind of noisy signals that this algorithm can help to squelch.
