Hey Michael, thanks for the demonstration. If you don´t mind I would like to give you the same advice I do to my class attendees when we are comparing different Mic in the free field and diffus field position. A: make sure that the height of the Mic is the same to get the same conditions in free/diffus angle. B: press once the "V"-Button to refresh the data before capture the measurement. C: there is a great option in the Signal Generator Settings: Stop Gen after Capture 😉
Good afternoon. Thank you for the video. I don't speak English, I'm sorry, that's why I'm writing through a translator. If I understood everything correctly, then you need to take into account one moment. To do this, there are calibration files for two modes of using this microphone. In free field and diffuse field. In other words, the manufacturer suggests that there is a difference in wings. But in general, for testing the directivity of the microphone, your experiment is very revealing. Thanks!!!
Yes, I totally agree that the manufacturer does provide different calibration for diffuse and free field measurements that help offset some of these changes. I just wanted to illustrate the differences and see if the mic orientation was as "big of a deal" as I thought it was.
Ears work in stereo. Is it possible to use stereo or figure 8 in large room, banquet hall, etc, to get measurements. A mic pointed at a speaker seams like a headphone as opposed to ears perpendicular to a source
You're right that ears work in stereo, but with these types of measurements we're not trying to simulate human hearing. Just gather the frequency response and IR at a single point in space. Then we can extrapolate how that will actually sound by standing and listening at that space ourselves once we tune.
I always wondered this because the IK multimedia ARC tells you to point the mic one way, and other videos say to point it another way... Glad this ended the debate, for me.
You want to see something really interesting? Look at the frequency response of your speakers and compare the data you capture. If it looks the same . Then your room is well treated. It looks pretty flat that’s great. Good video
Clever to match the phase response to ensure the capsule is in the same position. I will remember that one! Thanks!
Thanks, David!
Really enjoyed this and a nice little reminder to test test test.

Hello. At 6:02, do you use square drawing? Can you give me the name of that software? I thank you
It's called ScreenBrush.
