I am not clear on your request. Rescan of what? An EQ? What good would that do other than show the simple effect of the EQ?
Thank you, Amir for the analysis. I wonder what could happen if distortions were measured at a harmonic where 2 or 3 fundamentals meet. For example, you have a superposition of the fundamentals in a chord.
Example: A flat 51.9Hz, C 61.7Hz, and E flat 38.9Hz from the first or second bass octave (depending on whether one is counting from octave 0) or mid bass, the fundamentals that are one octave higher. All three meet on the C in the fifth octave, that is, 987.8 Hz. When music is played on any of my systems, there's high level resonance in my room. However, the resonance is as pronounced in my 4 good headphones as well.
Any comment would be highly appreciated. P.
