Has anyone seen a puredata implementation of Andrew Simper's dynamic smoothing algorithm?

No, but there is slop~ that can work for a similar purpose. slop~ functions as a controllable slew limiter. It's not an implementation of Andrew Simper's algorithm, but it can be used for signal smoothing/denoising sensors. It's a single pole. I'm not a filter expert, though.

Thanks a lot, I am aware of slop~, but I need exactly this implementation...

@trummerschlunk Maybe helpful......

David.

@trummerschlunk Here's my implementation of the 2nd (more accurate) version: dynamic-smoothing.pd
Not tested yet, so I'm not sure that it actually works ...

wow @manuels , merci!!

for the sake of completeness (and thanks to @manuels' inspiring patch), i'm adding the "efficient" version here (not well tested neither):

dynamicsmooth-efficient~.pd

... i really like this approach and i will create an external for it as well.

awesome! thanks

I've played around with @manuels ' (more accurate) version and it seems to be working great. Just figuring out nice values for my case, an advanced speech optimized audio leveler, which I will post of course as soon as it's working.
