Noise on Potentiometers even after FilteredAnalog

Hi Pieter,

I have quite a bit of noise on my potentiometer either using a Teensy 4.0 or a Teensy LC and I have tried using the FilteredAnalog and the Advanced version too. On both occasions I still have noise which I can't understand why.

I am using 10k linear potentiometers and have even tried just having those rather than a bigger controller. Can the quality of the Potentiometer affect the amount of noise? Will a PCB construction rather than breadboard will reduce the noise? Does writing A0 rather than 14 changes how the potentiometer act? I doubt that but asking just in case

Is there anything else I can try to reduce it? Thank you!
