Ok, it’s the perfect recording session and the mixing phase begins, but wait. what is that humming that I hear? You guessed it, ground noise. What is it and why does it happen? First of all, ground noise happens when wires or equipment hasn’t been properly constructed, bad wiring, or just a noisy electronic environment. You may or may not be the culprit, but the problem can be corrected. It just stinks that it happened on your perfect recording. Share with me some of your situations.
