HP is a well known smoother, but only problem it's not real-time friendly.
I changed this by making it 100% NRP
you got a few settings, I just added the "delay" value that allows you to get the "nth" value of the buffer instead of the last one, and you'll gain smoothness by augmenting it.
- extern int FiltPer =14; period of the MA
- extern int windowSize = 1500; rolling window size (in bars)
- extern int delay = 7; index of the final output buffer
