Immersive audio, or spatial audio, is a broad term for audio technologies that create a three-dimensional soundscape. Unlike traditional surround sound, which provides a horizontal ring of audio around the listener, immersive audio adds height channels to make a sound dome. This allows for precise placement of audio objects in 3D, immersing the listener in a hyper-realistic auditory experience. The crowd’s roar, the thump of the ball, the snap of a hockey stick, and the net rustle are all precisely positioned in the 3D audio field. When done right, fans get closest to being in the stands without leaving their living room.
Immersive audio technologies
Several immersive audio technologies have emerged, each with its approach to creating a spatial soundscape.
- Dolby atmos– Dolby’s flagship immersive audio format supports up to 128 separate audio tracks, including overhead channels. It’s widely used in cinemas and home theatre setups.
- DTS:X– DTS:X is a competing format that, like Atmos, supports object-based audio for precise sound placement in a 3D space.
- MPEG-H- Developed by the Moving Picture Experts Group (MPEG), MPEG-H is an open standard for immersive audio. It’s been adopted by some major broadcasters.
Capturing immersive audio
To create an immersive audio mix, sound must be captured in a way that preserves spatial information. This is achieved through specialized microphone arrays and recording techniques. One common approach is to use Ambisonic microphones, which feature four or more capsules arranged in a tetrahedron. These mics capture sound from every direction, allowing the precise location of each audio source to be encoded.
Mixing for immersion
Audio captured, the next step is to mix it into an immersive soundscape. This is where the power of object-based audio comes into play. Each sound source is treated as an individual “object” precisely positioned and moved in the 3D audio field in an object-based mix. The sound mixer places these objects using specialized software like the Dolby Atmos Renderer. They pan crowd noise to the sides and rear, position the crack of the bat front and centre, and even use the height channels to simulate the arc of a ball flying overhead. This level of control allows mixers to create hyper-realistic audio that mirrors the on-screen action.

Benefits of immersive audio in sports
The rise of immersive audio offers significant benefits for sports fans, broadcasters, and advertisers alike:
- Enhanced realism– Immersive audio brings the authentic sound of the game into the home, making viewers feel like they’re part of the action.
- Increased engagement– A more immersive experience increases viewer engagement, as fans feel more connected to the event.
- Accessibility- For fans who can’t attend games in person, immersive audio provides a taste of the live experience.
- Storytelling– Immersive audio gives broadcasters new tools to tell the game’s story, highlighting key moments and creating emotional resonance.
- Advertising Impact– The immersive experience makes advertising more engaging and memorable.
Integration with augmented and virtual reality is another area to watch. As AR and VR become more prevalent, immersive audio will be vital in creating convincing virtual experiences. Imagine “sitting” in a virtual stadium and hearing the game as if you were there.
Automated mixing is also on the horizon. Machine learning algorithms could analyze the game action and adjust the audio mix for optimal immersion. This could make immersive audio production more efficient and consistent.
