Best way to remove static?

#1

I am getting a lot of static noise from pisound when it’s running, and I can hear pitch changes in the noise as LEDs blink. What is the best way to reduce/remove this noise?

I am using pisound with a raspberry pi 3b+ and modep.

For power, I am using a 12v to micro usb regulator that plugs into my isolated pedal board power supply. (https://www.amazon.com/gp/product/B00U2DGJD2/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1)

Thanks,

Hi, could you try a regular 5.1V, >=2.5A power supply that plugs directly to an electrical socket? Usually the noise gets caused by a noisy power supply.

We recommend this supply: https://www.raspberrypi.org/products/raspberry-pi-universal-power-supply/

Got a truly isolated power supply, and this fixed my problem.
