WebSine sweep was played by a good loudspeaker of which I have the FR specs. 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.
