How Spatial Sound Can Change the Way You Play

If you’ve ever played Call of Duty with a headset, you know how important audio is — from footsteps creeping up behind you to the distant crack of gunfire. To enhance this experience, Call of Duty introduced Enhanced Headphone Mode, which uses 3D audio technology and HRTF (Head Related Transfer Function) to make sounds more dynamic, realistic, and directional. But what exactly is HRTF, and how can it elevate your gameplay? Let’s dive in.

What is HRTF and How Does it Improve Your Game?

HRTF simulates how sound travels to your ears from every direction, taking into account your unique ear shape and head structure. This is important because everyone’s ears are different, which means the same sound can be perceived in different ways by each player.

In Call of Duty, Enhanced Headphone Mode uses HRTF to give you more accurate spatial audio. With this, you can easily locate sounds — whether it’s an enemy running across the map or a shot fired from behind cover. The Universal HRTF Profile gives you these benefits within the game’s engine, but Personalized HRTF takes it a step further by tailoring the sound to match your exact ear shape.

Tuned to the Game: Customizing Sound for Call of Duty

Personalized HRTF doesn’t just optimize the sound for your ears — it’s also finely tuned to the Call of Duty game engine. Embody, the company behind the Immerse Spatial Audio technology, worked closely with Call of Duty’s sound team to ensure the audio responds perfectly to the game’s dynamics.

This means that both Universal and Personalized HRTF Profiles are calibrated to how sound behaves in the game world. For example, the way sound moves from in front of you to behind you, or how it transitions from on-camera to off-camera, or the sound travels above you and below you has been carefully adjusted to make everything feel more realistic and accurate. Whether you’re crouched in a corner or running across an open field, the sound will react accurately to your position, heightening immersion and gameplay precision.

How Personalized HRTF Works

Getting a Personalized HRTF used to involve complicated and expensive setups. Now, thanks to modern technology, all it takes is a simple smartphone scan. Embody’s system analyzes your ear shape and instantly generates your custom HRTF — giving you the best possible sound experience, tailored specifically for you.

1. Scan the QR code in the Enhanced Headphone Mode settings screen.
2. Position your phone so that your face fills the selfie camera.
3. Turn your head slowly to the left and right to capture your ear shape.

No special equipment needed — just a quick scan, and you’re good to go.

Why Personalized HRTF is a Game-Changer for Call of Duty

Personalized HRTF offers significant benefits for players:

• Precision: Hear footsteps, gunfire, and other critical sounds with accuracy.
• Faster reactions: Accurately detect where threats are coming from, giving you an edge in those split-second decisions.

With Call of Duty’s finely tuned spatial audio, you’ll experience every sound exactly as it’s meant to be heard, providing more immersion and helping you react faster than ever before.

Final Thoughts: Upgrade Your Audio, Upgrade Your Game

Enhanced Headphone Mode is already a game-changer, but Personalized HRTF takes it to the next level. In just a few seconds, you can unlock the full potential of 3D audio, ensuring that every sound is sharper, clearer, and more precise. So, the next time you jump into a game of Call of Duty, scan your ear and hear the game like never before.
