In audio signal capturing by microphones, there is a leak of unwanted mechanical noises through the microphone stand, caused by vibrations on stage, by the kick drum, by low frequencies of the amplifier, by the artist's choreography on stage, etc. One of the conventional solutions is to adopt electronic recourses, such as noise gate reduction, re-equalization (shut down of low frequencies), etc. Thus, no doubt, we are interfering with the signal's dynamics, reducing our system's head room, consequently...
