Web6. It depends what you mean by "normalised"; it also depends on your software's choices. "Normalised" is a word often avoided by statistical people, because it is ambiguous as between (a) scaled or standardized (e.g. to total 1 or to mean 0 and SD 1) and (b) transformed (approximately) to normality, meaning normal or Gaussian distribution.

Now these FR charts have different "dB ranges": Mic FR: -90dB to -10dB. Speaker spec: starts at -45dB, moves to 85dB and stays mostly linear. The goal is to normalize the mic FR data w.r.t to the speaker's FR spec and then use that result to create an (inverse) FIR filter.
