Right, I understand that
I am still confused though about something else, let me try to explain.
Say there is a speaker producing a sine wave. For arguments sake lets say it starts at its peak at +2 and then drops to 0 then to -2 then back to 0 and so on.
If I have a microphone picking up this sound (the wires are unaltered) will it produce a wave that starts at its high (peak)? And therefore, if I switch the wires will it then produce a wave that starts at its low, in other words the opposite polarity (or phase?) as the initial source?
I hope that is clear,
Thanks,
Adam
