In one small area of my studio near my mains circuit breaker electrical panel i have some type of electrical interference and all my microphones except the neumann mics have hum when turned in a certain direction. Even though we can still discern p waves in this strip and we can see that the rhythm is irregular possibly sinus arrhythmia the artifact prevents us from accurately evaluating the strip. If i turn the mics 90 degrees the hum disappears.
