Have you ever tested the acoustics in an empty room by whistling or clapping? It brings to mind how sound is affected by a room’s size, structure, and contents. Even when using optimally positioned speakers of exceptional quality, the room negatively impacts sound quality considerably. Surfaces such as windows and furnishings and the geometry of the walls, floor, and ceiling add unwanted resonance and coloration, making the bass either boomy or less punchy, voices less natural, and the dialogue less intelligible. The effect on frequency response is typically ±6 dB in the midrange and ±10 dB at low frequencies.
To compensate for this and to optimize the in-room response of your speakers, Anthem Room Correction (ARC) measures the output of each speaker relative to the listening area then, through a series of calculations, adjusts its output. Not only does ARC correct peaks and dips in a speaker’s frequency response, but it also preserves the beneficial acoustic attributes of a room—attributes based on proven psychoacoustic science (the study of how humans hear and experience sound).
What is ARC®?
Anthem Room Correction (ARC®) is a proprietary digital signal processing system that allows you to quickly and accurately optimize the performance of your audio equipment to better suit the unique parameters of your room. By listening to your room’s acoustic signature, ARC® can tune your equipment to correct for the performance-robbing effects (reflections, resonances, standing waves, etc.) of the various surfaces and other obstacles in your room. You’ll actually hear the difference ARC® makes.
How does ARC® work?
ARC® digitally compares a room’s acoustic signature to that of the lab standard. It measures the response of each speaker relative to the listening area. Then it uses advanced algorithms to eliminate the negative effects of the obstacles in the room, adjusting response and correcting phase effects. When ARC® removes the obstacles, what’s left is the lab standard performance.
ARC® is easy to use, and just a few simple steps can optimize your speakers for your unique listening space. ARC® is sophisticated, one of the most accurate and detailed digital room correction technologies available today. ARC® will work tomorrow, too; with constant advances and updates available for download on the Anthem website.
