Hi all!,
I'm making a sound trigger, using an electret-mic. When I see the signal from the mic, on an oscilloscope, sometimes the signal startsmoving up and sometimes starts moving down.
I thought that the sound waves, when they hit the microphone, would make the wave always start moving upwards.
What would be the explanation?
