Hello , I have been trying to use the microphone on Nano Pi Neo . I currently have a microphone listening to a tone generated by the PC .
I am able to get a sine wave output but there is always some transient noise at the starting for the first 40 samples or so . What is the reason for the transient noise and how can i get rid of it ?
