[PD] microphone cleaner advice

[Yu Lao]

a noise cancelling mic would require 2 capsules, one cardioid pointing the
the wanted source (you) and another picking up the opposite direction
assuming that's where the noise is and then phase inverts the 2. as the
noise hits both capsules at the same time but at opposite phases it should
work quite ok.
