Dirac Live Room Correction

Achieving audio perfection isn’t easy. You need top-notch speakers, a premium AVR, and high-resolution content. You’ll also need an entirely different room setup because most spaces aren’t designed with acoustics in mind. So unless you’re building a home from scratch—or live in a really cool circular space (like a Hobbit?!)—there’s not a lot of options to improve your acoustic layout. That’s where Dirac Live Room Correction technology comes in.

The problem

But how? Sound waves move…a lot.

Picture your typical rectangular space like a living room, basement, or bedroom. Sound waves collide and collect in corners, bounce off walls, and disrupt the natural flow of sound to your ears. Another way to think of it is like a kids’ ball pit: you jump in and balls go flying in every direction, awkwardly filling the space and getting stuck in corners; some will even bounce right back at you.

A game-changer in the world of audio calibration, Dirac Live fixes the problems associated with square and rectangular spaces. It doesn’t just adapt to your room; it transforms it. Utilizing sophisticated algorithms, Dirac Live meticulously analyzes your room’s acoustics, identifying problematic frequencies and reflections that distort your audio experience.

The solution

Dirac does the math for you.

Dirac Live is a very user-friendly tool. Named after Nobel Prize-winning mathematician, Paul Dirac, Dirac Live Room Correction technology applies proprietary formulas and algorithms to perfectly balance sound for your unique room and speaker layout.

How it works

Measuring frequency response and adapting audio to amplify some and weaken others strategically.
Dirac Live then applies precise adjustments, amplifying certain frequencies while weakening others, ensuring that the sound reaches your ears at precisely the right moment no matter how your room is laid out or what speakers you use.

Remove your room, add the awesome

Ever feel like your speakers just aren’t quite hitting the mark? Dirac Live changes the game by fine-tuning your room’s acoustics, so it feels like the band’s playing right in your living room. With this improved sound stage, you can say goodbye to flat sound and say hello to pure, immersive audio.

Fulfill your AV potential

Life‘s too short for mediocre entertainment experiences. By fine-tuning every frequency for optimal performance, Dirac Live fulfills the true potential of your Onkyo AVR and speakers. Its precision calibration will provide you with a newfound appreciation for the clarity and depth of your favorite content.

Built-in is simply better

You can dive into the world of premium audio calibration right away with Onkyo AVR’s built-in Dirac Live Room Correct Full Bandwidth. This simple, out-of-box functionality means you don’t have to fuss with additional upgrades or purchases—better sound is built into your Onkyo device. Amazing AV experiences are only a few clicks away. What are you waiting for?

With three presets available at your disposal, you can customize your listening experience with a click of a button. Calibrate your Onkyo AVR via Dirac Live and save your favorite three settings. You can create one present for listening in your favorite armchair, another for entertaining a room full of people during movie night, and a third for jazzy nights at home with a glass of your favorite beverage.
