I won't risk getting out of my depth. My comment was simply saying there are unique nerve signals from unique points across the cochlea which uniquely convey the information "this frequency is currently being heard at this volume". To say that that information is what we perceive... that's not an argument I'd make. But it is a step along the process.

Everyone knows we "see" in rgb, but few people seem to know we "hear" in frequencies more than we "hear" in waveforms. That's my point.
