Hi there

I was wondering if there is a way to filter out/reduce the noise from sensor inputs through the adc~. Often the sensors values differ in between a very low range, so hopefully, someone out there has tried to stabilize this before.

Is there an easy way to store the previous adc/sensor value and compare it to the new value, in that case, how?

An interactive example, however not in PD code, can be seen here:
https://codepen.io/dxinteractive/pen/zBEbpP

It has to be imported into 'bela', so external objects like [smooth] and [once] are unfortunately not usable.

All the best

@abargum I am pretty sure once and smooth were abstractions...... here they are anyway..... stuff.zip
Does Bela give you [expr] though?
Here is something similar........ bang in range.zip

Hi @whale-av , thanks a lot for the answer and the abstractions!

How would you use them in my case? Since the sensor keeps sending I end up comparing my new value with itself, and not an old value.

I would like to say:
If (newValue > oldValue+5)
send newValue
otherwise send the oldValue (then the sensor has not been effected enough)

Am I thinking wrong?
