Hi Chris,

I thought your last puzzle would be a very high quality measurement mic. 😆 (I just got an Earthworks M30 mic and will companion with my Anubis and Audiolense XO).

Any reason to think the Earthworks M30 would yield any different results using Audiolense XO?

Less calibration is better. M30's FR is very flat (guaranteed < +/-0.3dB until 30KHz) and you can even use it without calibration file. If you use calibration file you can sweep up to 40KHz!

 

I don't have UMIK-2 but I own Sonarworks' and here's the comparison chart (rendered from the calibration file):

As you can see Sonarworks' high frequency rises un-naturally and then drop somewhere from 11KHz then stop at 15KHz (vertical flip the chart  = original FR) which prob would cause more errors when computing / generating filters.

 

I personally think that UMIK-2's 192KHz sampling rate really doesn't matter. You have to check the calibration file then decide to use it or not. But unfortunately the website didn't provide any FR-related information...

it is unclear to me where an M30 gets plugged into, if not USB

M30 is a condenser mic and needs 48V phantom power to drive it. Looks like you need an USB interface with 48V for analog input...
