As a side note.... the floor question (which should maybe be a different thread really).

it becomes of particular relevance mostly in Live rooms.... the impact it has on the recording is often far greater than on the response of the room ...

a lot of things are recorded with Mics close to , or on, the floor surface....

at which point the behaviour of the floor surface and material itself becomes more important than it is as an overall factor in the room's general response.

now we're heading in to the realm of "micro acoustics" if you like....

examples, recording acoustic guitar , or cello.

where what the floor surface is, between the Mic and the instrument , makes a huge difference to the recorded result.... (witness the old home recording tricks of sticking a piece of wood on a carpeted floor between the instrument and the mic... or , a rug on a wooden floor between the instrument and the mic.... and endless variations on that theme )



In a control room environment, one designs a floor to behave in a controlled and balanced fashion , and it's integrated in to the room response as a whole, and the response at the mix position , aiming for a balanced neutral result.


in a Live room, you have to consider the actual use of the room, which means considering the contribution of the floor in a real recording situation, NOT just as a contribution to the overall room response.




the same is true for ceilings when one starts looking at high overheads on Drums , and choirs etc...
