Jeff, thanks. Yes, I have a firm grasp of the process outlined in your relative acoustic offset paper, I just did not explain myself well enough. With the three measurement method, the summed
response in the overlay doesn't need to be ruler flat even though it should be an exact representation of the individual driver responses. It may be a touch easier for the dips and peaks to be present to help align the calculated response and may reveal testing atmosphere anomalies, imo. If there were too many irregularities in the waveform, I would essentially treat the process as ancillary data to simply provide me with offset numbers. Provided all constants remain unchanged, though, I'm going to have as accurate acoustic measurements as I can and test the sim in PCD before even putting the mic away. I'm using Omnimic btw, so I won't need to extract minphase etc. Thank you so much for PCD!
