Basics and application of loudspeaker/room optimization
What is loudspeaker/room optimization and why to use it?
Without surprise, loudspeaker/room optimization uses a digital audio processor inserted before the loudspeakers to correct loudspeaker and room imperfections. The processing is very accurate as it is based on real acoustic measurement of the actual room. The most advanced and efficient methods are using a 3D microphone as a room acoustic is a 3D physical event.
Combining passive and active acoustics
At the very beginning, it is important to establish that loudspeaker/room optimization is complementary to acoustic treatment; it is not a full replacement for a proper acoustic design. loudspeaker/room optimization can improve a lot of acoustic aspects but not all of them, as it will be developed in the next section of the article. But on the other hand, passive acoustic which dominated control room design up to recently, is a combination of science and alchemy that never achieves perfect results even in expensive no-compromise approaches such as Hidley, Bob Walker’s “reflection-free zone” or “Controlled Image Design”. In addition, the room acoustic is highly influenced by additional factors such as furniture, doors and windows in the room, the mixing console and its reflective surface,…
