I have a stream of numbers coming in (between 0-127) that fluctuates a bit but stays about the same depending on how I twist my potentiometer (using an arduino and demuxing in max). I need a way to stabilize the stream.

I am hoping for some kind of averaging patch or object.

Each of those solution has advantages and disadvantages... take the best depending on your need.

A few ideas:
- zl stream + mean
- zl stream + zl median
- slide
- line

thank you for your quick response, I appreciate the support!

I'll try these out, I'm sure I can one of them to do what I need

may be this could help... split stuff over gray panel...

for the rest of the treatmùent you'll need jasch objects 

i used it to stabilize sensor datas and scale them...

Interesting topic, i'd never think about using [zl median].

Here is a Graphical test patch for these objects. I found that [zl median] could be better in the case the noise from the sensor would be a crackling noise. for the rest i'm not sure what are the advantages/disadvantages, but differences can be felt in this patch.

By the way : Does a "zl median" object exist somewhere in signal domain ?? (signal made of median values of the n last samples)

Many people find lp.stacey useful for this sort of thing.

You'll find lp.stacey (with an example doing what you're after) in the Litter Starter Pack. Caveat: the Starter Pack is happier with Max 4, although the object does work in Max 5.

Complete Max 5 support is in the Litter Pro Bundle.

okay, so here's what I've put together and it seems to be working really well

and draws a curve or "ramp" based on the changing median value at a rate of 50 ms

and feel free to use my solution for your application!

this grabs 20 fluttering digits
finds the middle most value

averaging number stabilizer?
