Sorry I think you got the wrong comrade, this was my first reply. I agree with you, I just think that the high and low pitch is the worst possible choice for the argument. Like hot and cold have no external comparison, but the qualia of high and low pitch is very literally connected to another sense (in this case the sight of a low pitched subwoofer or such). Even when moving and causing the Doppler effect to you as observer, that anchor still exists just with a shift that is also externally explainable.

Sight, hot/cold, all kinds of smells, all have a sense of disconnection between sense and qualia. How you hear complex sounds (filters or such) introduces qualia

But remember, we actually agree, I just think your example wasn't good to convince anybody else
