I have a notebook with a Umik-1 microphone. I have some questions on measuring car audio as it seems you would do it differently from rooms.
1. It seems that you would use mic pointed to the windscreen with averaging of 4-6 positions around the head area with sine waves to get the true FR of each speaker at a time before eqing the result? Or you would use a 30 sec averaging with 90 degrees cal file moving the mic around your head area with RTA/Specturm Pink noise PN? Which would be a better measurement technique?
2. With a Umik-1 I would not need any sound file calibration via REW or loopback and I can trust the group delay or impluse to get my time alignment correct between the 3 way active drivers in my unit?
Any other tips to measure my car audio and get the crossover between the 3 way active speakers would be welcome.
Thanks!
