## Param Smoothing?

Apr 16 2012 | 6:33 pm
Hello,
Just wondering what others do for smoothing param values going into Gen~. I hear a lot of grit when I change values with param messages. As an example I am controlling various amps [*] with param messages but it is gritty so instead I have to create more inlets and use the pack/line~ combo outside. Is there a better way - apologies for the basic question.

I use history and mix to build something that's essentially slide~:

Note that the timing is going to get off for long values because it's an exponential decay. Somewhere around here I've got a correction formula...

Animal Peter - timing is not so important for this - a Haas Effect and a Phase Panner. Simple enough but should introduce to some of basic stumbling blocks :)
Cheers

So I had a little time and I finished the Haas Panner. Even though it is not much I thought I would share it. I am never fully confident when sharing but it is a nice effect and works well for me. I made it for Live and there is simple presentation.

Dear AudioLemon, thanks for sharing this. I was about to build a haas panner, but then found this! The patch is great and means that I have no choice but to get learning how to use gen~!
I hope that you don't mind if I use this to simplify into a single pot type panner to use the 0-0.7ms range to pan (for a mono track of course).
If so I will post if and when I complete and it works!

Re the original question, you can a) instead of using a param, send your value to a line~ object outside of the gen~ and send that signal into gen~ via an in object, or b) ramp to the new value over some number of samples within gen~. Here's an example of the latter method, although it's probably more efficient to use the former method, because line~ is smart enough to stop calculating once it has arrived at its target value, unlike the gen~ method shown here.
