Here is a beginning of Waldstein sonata as I was experimenting with acoustics today 

What microphone should I use I wonder. Just bought a completely useless Apple microphone. Is there a way to attach a professional mic which I have which requires usb to iPhone somehow?

I use the built in stereo mics of a zoom h5 recorder to my iPhone. It’s an iffy deal though. You don’t know if your phone video has the “good” audio on it until after the fact. Nowadays I just record the video with my iPhone and use the h5 as a stand-alone recorder and combine on my pc. That’s a pain though.

Thanks so much for sharing this. Very helpful, will have to play with technology and try.
