I've seen it. The best display is in NY at the Historical Museum.

It's not for this task, it's just a new machine with sufficient speed for BEM.
So it should have more than ample speed for any plausible calculations on this task.

My intention is to get back to this, but my circumstances are not making that easy.

Sounds good to me, and that's certainly understandable - I'm fairly certain we all have more things we'd like to do than we are able, no matter our age.

I ask about the data format because I have built a tool that automates polar measurements at work, and I'd love to spit out the correct format for use in this tool. Is there an example of the proper data somewhere in this thread? If not, could one be posted so I can follow it?

I added the commonly available formats and mostly added some comments to explain the format, for the most part this means expecting a directory full of files which are named according to the angle they represent and that contain data in some known format. The supported formats being

- wav
- dbl
- ARTA PIR
- REW txt format

There is then the HolmImpulse export format which is described in pypolarmap/load.py at master * 3ll3d00d/pypolarmap * GitHub

This is a semi colon delimited format where the angles have been embedded in the header (aka the measurement names) as a convention
