Simply put, Anthem Room Correction quickly “corrects” the effects that reflective surfaces such as walls, floors and ceilings have on the sound radiating from a loudspeaker. Removing the effects of these obstacles allows your audio equipment to achieve a more natural sound in any room, as close to the lab standard as possible.

On a more complex level, ARC® is a proprietary digital signal processing software that works with a specially-engineered calibration microphone and your PC to quickly and easily optimize audio for your unique listening space. Anthem engineers developed the ARC® system while researching how to replicate the audio-lab standard of performance in non-lab environments. This groundbreaking research was conducted in conjunction with the National Research Council of Canada, the Canadian government’s research and technology organization.

Anthem engineers realized that real world listening experiences had little in common with the controlled environment of the audio lab. That’s because even the best loudspeakers are affected by room anomalies like furniture. These obstacles cause standing waves, resonances, and reflections that can color the sound you hear. Imagine the sound waves coming from your speakers as ripples on a water surface. That makes it easy for you to understand how the ripples of sound bounce off any obstruction they encounter. You can immediately see the benefit of removing the obstacles.

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.
