I'm trying to build a list accumulator with normalization. I've got that far (though I'm severly mathematically challenged, so please feel free to fix what I already think I've done!), but what I want to add is an optional "forget" rate. What I'd like is a slightly more stubborn version of what I already have -- one that will change more slowly over time. Make sense?

[ edit: that is, same peak of 1.0, but smoother curve... yes? ]

Here's what I've committed, thus far (need Lobjects, btw):

If the list size is constant you could do your "forget rate" easily 

Here's an example for 3-element lists and a forget rate of 5.

If you require variable list lengths or changing forget rates you 

would need to do some scripting with this approach. At least stacey

If the list size is constant you could do your "forget rate" easily  
with a bank of lp.stacey objects.

If you require variable list lengths or changing forget rates you  
would need to do some scripting with this approach. At least stacey  
does the math for you.

I didn't realize stacey had that option, but alas, my current application uses a list of around 50 members (I'm doing some fuzzy stuff), so it would be a little cumbersome to do with stacey. I think I can get my head around the math, so I may do it in java...

btw, I had a look at dspaudio and became quite curious about iCE. Is there any more documentation I can look at to get a better idea of how it might be used, or what it's capable of doing? I could just use a little more detail.

We're working on it. As it becomes available it will be on the

We're working on it. As it becomes available it will be on the  
DSPAudio site.

Laccum + normalize with "forget" rate?
