Good day guys and gals,
I'm using the teensy in an automotive environment. The sound recorded through the teensy is fine until i connect the teensy to the ground of the car.
AGND is used on the audio line, and GND for the ground.
Once both are connected i get alternator whine sound. Is there any trick I can use to minimize this?
