Of course, whan you change the amplitude of any 20Hz (or other) waveform *during* the waveform, then you get wave form distortion, and in fact AM *modulation* complete with sidebands.
LOL From this follows: The true Audiophool has NO volume controls.
Amazed you will be how many patents are granted for the "perceptually optimal" volume update curves and the algorithms for the volume transition.
