Hi G.E.
We are going to have a total of 18 diffusers on the ceiling. The idea is to make the room sound live so we follow some kind of symmetry. The place for each instrument in the recording is not fixed so we can place them whenever we want and ''record'' the acoustics of the room as well as the instrument, this is a job for the matched paired earthworks
Earthworks - M30 - 5hz to 30khz Measurement Microphone that i got for the acoustic measurements. The overall idea is a more uniform sound than just the dry sound of the instrument
Future step is some screen panels (similar with the ones you made, very cool by the way) with adjustable diffusers, absorbers and reflectors for variable acoustics
