I have an Aco Pacific 70121/2" measurement microphone which I purchased with mellisa back in 1995 is basically flat from 3HZ to 40KHZ. I plan to use it with REW software. Rew needs a Mic. calibration data to be installed. The cal data consists of frequency, amplitude and phase angle. I only have the Mic frq. response curve, no phase response. I need to buy a usb audio interface.
Question 1. How do I get this data into REW?
Question 2. The software called Vituixcad has a spl trace tool that can convert the frq. response graph into a .txt file. Windows 10 or google chrome won't let me install it. For security reasons.
Question 3. How do I convert Mic. sensitivity from dB ref. 1V/Pa into db spl? 7012 sensitivity is -36 dB.
Have not used the 7012 in 2 decades. Not willing to have it cal'd for $135. and not willing to buy a Chinese usb mic.
Your help will be greatly appreciated. Mellisa is a dos based program. I still have the pc but it won't boot up due to a dead bios battery. no longer have the serial mouse or the din plug keyboard or the crt monitor that I once had.
Best regards,
