So the first question a lot of you may have is... "what in the world is an acoustic diffuser?". You can read about the basics of acoustics in our
Studio Design Blog. The general point of "acoustically treating" your control room (the room with the computer or mixer where the engineer sits) is to try and minimize any effects or colorization the room may have. I am sure you have noticed the change in your voice when you walk from a carpeted living room into a tile bathroom. The tile is brighter, more echo-y, right? Every room changes how sound, well, sounds.
When you are mixing music you want to be listening to the sound coming out of the speakers. If sound from the speakers is bouncing off walls and the engineer is also hearing those reflections is makes mixing much more difficult.
If sound hits a blank wall it will just bounce off that wall at close to the same force that it hit.
Diffusers scatter a sound wave when it hits the wall, reducing the power of each reflection, keeping the reflections from bouncing all the way back to the engineer.
