I have an unconventional way of thinking about EQ.
Where most people would say that a given frequency is too loud, I identify that frequency as arriving to soon. Where most people would say that a given frequency is too quiet, I identify that frequency as arriving too late.
I make this assertion because equalizers cause phase shift. I am not talking about FIR filters, I am talking about IIR filters. If you doubt that humans can hear phase shift, please experiment with JUCE’s biquad all-pass filter module.
Does anyone else think about EQ this way?
