Which Umik Cal file should I use for Dirac?

[paulwgraber]

I was always told to use the 90 degree file but other users have told me no to use the regular one?
Interesting enough Chat GPT says do not use the 90 degree

Not a dirac user, but I did a little searching. Look at post 6 in this thread https://www.minidsp.com/community/threads/umik-1-mic-position-and-polar-plot.15895/
