[QUOTE="Michael John, post: 202184, member: 830"] Hi Mark, The "Normalise" check box, when checked, scales or shifts the magnitude of the measurement so that the highest point in the spectrum is at 0 dB. The aim is to bring the measurement in range, if it's too high or too low (as I've found happens often, at least in my setup). However as you've found, when measuring multiple drivers, Normalise will cause each measurement to be scaled differently, which can result in different levels between each FIR filter design. From your feedback, I'll add an import option to manually set the input gain scaling. That way you can use the same gain for each driver design, and still bring all the measurements in range (if they are too high or too low). Give me a few days! :-) Thanks. Yep, that's the intent. I'm slowly coming to the conclusion that my ideal EQ processing chain (per channel) is a bank of, say, 4 to 8 biquads for IIR filters, followed by 2000 to 4000 taps of FIR, plus maybe a delay line. Hopefully some speaker processor hardware folks are watching. :-) Yes, that makes sense. I need to think over this some more. In the meantime - and you maybe be doing this already - you can save your target designs as project files (just like for the regular workflow) and quickly create a new target by modifying a previous project. Thanks! Michael [/QUOTE]
