high pass filter on EM172 capsules

["Gianni Pavan" gpavan1960]

Hi all, EM172 and other capsules with PIP powering are a great resource for
building both specialized and general purpose microphones. I some cases it
would be useful to have a high pass filter to limit low frequency noise,
e.g. generated by breeze or wind.

I would ask to those more expert than me in electronics if it is possible
to insert a simple HP filter in between the capsule and the recorder input,
eventually also considering to replace the PIP from recorder with a
dedicated battery.
