Six Schumann resonators is all you need!
Modifiable room acoustics which change to fit the music is a fun idea.
But what recordings will one play in this room? All close mic’d or processed to remove room sound so that your individual sound room creates the room environment?
If one plays conventional recordings into a “sound room,” one is adding your room sound to the room sound already on the recording.
I know from experience that adding artificial reverb - even excellent acoustic based convolution reverb - to a recording already containing room sound is tricky. Getting a physical room to match or compliment a recordings existing ambiance would be even more tricky.
