A room can be controlled mechanically and/or by DSP (Diffusion/absorption/reflections ratio and locations relatively to listening position with a LV/ASW ratio under control mechanically and by DSP)..
This room seems to be under some relative mechanical control with diffusion panels but i dont know for DSP or for others means and devices ...
To judge it i must be there ...The fact that on a youtube video the sound impression impress by clarity means not much if i want to judge other acoustics factors as the main ASW/LV ratio for a listening position...
By the way straight out of youtube clarity aside the sound is fatiguing a bit, too much in my face not around me...I cannot judge a system without being there ...![]()
Also we must not feel the sound of our "room" when listening to music but we must feel the Recording set of trade-off choices by the recording engineer translated in our room acoustics but without being impeded by our room acoustic... i felt the "room" in this youtube video not so much the recording... I cannot judge anyway without being there ... I am not gifted as you are it seems ... Nor as much knowledgeable ... But i know how to make my system/room great...
@mahgister do you consider the room featured in the following audio recording an acoustically controlled room?
