Parameter smoothing in gen~

July 13, 2013 | 5:02 am

Hi guys,
trying to do parameter smoothing in gen~.
Any strategy?
I’ve tried this following simple thingie but doesn’t provide the required amount of smoothing.
Have to use audio rate parameters outside of gen~ (i.e. using sig~ )

Hi Alfonso

Gregory Taylor’s response to my recent "line~ as counter" question here might help. Very nice interpolation idea.

In itself the strategy works well, it’s just that the argument for mix should be much closer to 1. This setup behaves similar to slide~.

many thanks guys! useful infos!

I just made this gen~ patch inspired by supercollider’s "lag3". Very useful for parameter smoothing. Unlike line~ it has a smooth start and end, in some cases producing less unwanted artifacts.

I made this, it’s simple. For faster response the .01 could be higher (and .99 changed the two coefficients still add up to 1). I think it could be twice or more faster, but I didn’t need it.

One nice thing is, with faster audio rates, the difference between samples is smaller, so the coefficients don’t need to change when sample rate changes.

i use the basic idea of a moving-average filter:
0.5(n + n-1)
but alter it for differing needs….
(uh… in case it needs be said: n = current sample, n-1 = previous…)

I really dig Tarik’s though :D
