That expr handles increasing vs decreasing separately, with two separate smoothing coefficients (the .1 and .2). Break them out into additional inputs to [expr] and those can be changed dynamically as well.

Re: [PD] smoothing numbers: something like Max's "slide" object?
Thanks daniel; i'm aware of this technique. Im specifically looking for a smoothing method that allows variable amounts of smoothing, and also implements a way to have increasing values be smoothed differently than decreasing values. Any thoughts on that? -ali On Wed, Jan 18, 2017 at 3:45 PM, Daniel Iglesia wrote: > Grabbing the previous incoming value, and one [expr] should do it, to > implement a first order filter > > y[i] := y[i-1] + α * (x[i] - y[i-1]) > > as > > [expr if($f1>$f2, $f3+.1*($f1-$f3), $f3+.2*($f1-$f3))] > > where $f1 is the incoming number, $f2 is the previous incoming number, the > output of this expr is routed into the second inlet as $f3. > .1 is the smoothing coeff for increasing, .2 is the smoothing coeff for > decreasing. > > So: > > [(floatatom)( > | > [t f f b] > | \ / > |\/ > |/\ > | / \ > | [float] > | | > | | > | | > [expr if($f1>$f2, $f3+.1*($f1-$f3), $f3+.2*($f1-$f3)) ] > | > | > [(floatatom)( > | > > > > On Wed, Jan 18, 2017 at 11:18 AM, Ali Momeni wrote: > >> Hello all, >> >> Can someone point me to an existing abstraction/external that behaves >> somewhat like Max's "slide" object?

Re: [PD] smoothing numbers: something like Max's "slide" object?
Grabbing the previous incoming value, and one [expr] should do it, to implement a first order filter y[i] := y[i-1] + α * (x[i] - y[i-1]) as [expr if($f1>$f2, $f3+.1*($f1-$f3), $f3+.2*($f1-$f3))] where $f1 is the incoming number, $f2 is the previous incoming number, the output of this expr is routed into the second inlet as $f3. .1 is the smoothing coeff for increasing, .2 is the smoothing coeff for decreasing. So: [(floatatom)( | [t f f b] | \ / |\/ |/\ | / \ | [float] | | | | | | [expr if($f1>$f2, $f3+.1*($f1-$f3), $f3+.2*($f1-$f3)) ] | | [(floatatom)( | On Wed, Jan 18, 2017 at 11:18 AM, Ali Momeni wrote: > Hello all, > > Can someone point me to an existing abstraction/external that behaves > somewhat like Max's "slide" object?

[PD] smoothing numbers: something like Max's "slide" object?
Hello all, Can someone point me to an existing abstraction/external that behaves somewhat like Max's "slide" object? Specifically, i'm looking for a way to smooth (low-pass) floats (control rate) but with the ability to smooth out increasing and decreasing values differently.
