Very interesting. Thanks for sharing this. I'll play around with it a bit, check the guide, and come back to discuss. Forgive me if any of the following is covered in the guide, and if so feel free to simply let me know it is rather than waste your time on a more detailed reply.
A few preliminary questions:
In tailoring it to specific microphones do you import the published frequency response and polar diagram? Any other data specific to the microphone? What happens for microphones lacking good published graphs? And how are differences in how those graphs are presented by various manufacturers handled?
Helpful to include specific microphones commonly used by concert tapers. Many are already there. And good to see the suggested additions being incorporated.
