			; Notes
			; Notes on polymorphism
			; I could make this sox-mix-console (non-consistent) a method where a list of effects will be applied to each sound in the mix-console
			; OR: keep this as an extra function for the player
			; I can't use pipe-input to the mix-console as it makes sox-remix instances with pipe-outputs ->is a pipe in a pipe not possible?
