Dear John,
The bottom response in purple is the vector multiplication (A * B trace arithmetic) of the top two responses and creates that odd peak at 24,000 Hz. The original sweep was 0 to 24kHz so I'm guessing it's some sort of an overflow error due to end of data there. I cannot find a way to get rid of it.
I have tried:
* trimming an impulse response is not possible (you can export it trimmed as measurement but lose impulse property when you import back)
* tried a notch filter but EQ goes only up to 22kHz
* some HF tail manipulation is possible but only with a minimum/excess phase copy
* tried merging it with various flat target response shapes (blended or not)
Your help (or anyone else's with some info) is much appreciated.
(and my compliments for the zoom capture capability you've added in the latest version)
