What Is Spatial Audio?
Spatial audio is an advanced audio technology that creates an immersive 3D sound experience for users. It simulates the way sound is perceived in the real world, allowing audio to be heard from different directions and distances, providing a sense of depth and surround sound.
Traditional audio systems deliver sound directly into the listener’s ears, but spatial audio goes beyond this by incorporating spatial cues, such as direction, distance, and environment, to reproduce a more realistic and captivating audio experience.
With spatial audio, you can feel like you’re in the middle of a concert, or that the action in a movie is happening all around you. It adds an extra layer of depth and immersion to your audio content, whether you’re listening to music, watching movies, playing games, or attending virtual meetings.
This technology is particularly beneficial for content creators and professionals in industries such as gaming, virtual reality (VR), augmented reality (AR), and film production. It allows for precise audio positioning, enhancing the overall audiovisual experience for users.
Apple has introduced spatial audio on their AirPods Pro and AirPods Max, making it accessible to a wider audience. But how exactly does spatial audio work? Let’s dive deeper into the technicalities.
How Does Spatial Audio Work?
Spatial audio works by leveraging motion sensors and advanced algorithms to create a realistic and immersive sound experience. The technology takes advantage of head tracking and dynamic head-related transfer functions (HRTFs) to simulate the way sound interacts with the human ears and brain.
Here’s a breakdown of how spatial audio works:
- Head Tracking: When using compatible devices like AirPods Pro or AirPods Max, spatial audio utilizes the built-in gyroscope and accelerometer to track the movement of your head in real-time. This allows the sound to stay fixed in space while you move, creating a more natural and immersive listening experience.
- HRTFs: Head-related transfer functions are unique filters that determine how sound reaches each individual’s ears based on their head shape, ear anatomy, and position. By analyzing these factors, spatial audio can mimic the way sound waves interact with the listener’s ears, providing a sense of direction and distance.
- Audio Encoding: Spatial audio content is encoded with metadata that contains information about the sound’s position, distance, and environment. This metadata is then used by the devices to process and render the audio in a way that creates a three-dimensional soundstage.
- Device Playback: When listening to spatial audio content on compatible devices, such as AirPods Pro or AirPods Max, the device takes the metadata and applies the necessary transformations to the audio signals. The result is a dynamic and immersive audio experience that adapts to your head movements.
By combining motion tracking, HRTFs, and intelligent audio processing, spatial audio creates the illusion that sounds are coming from all around you, rather than just in your ears. This makes for a more realistic and engaging audio experience, especially when paired with visual content.
Now that you have a basic understanding of how spatial audio works, let’s explore the devices that support this technology.
Devices That Support Spatial Audio
Spatial audio technology is supported by various devices, including both Apple and non-Apple products. Let’s take a look at some of the devices that offer spatial audio capabilities:

Now that we’ve explored tips for optimizing the spatial audio experience, let’s distinguish the difference between spatial audio and surround sound.
Spatial Audio vs. Surround Sound: What’s the Difference?
Spatial audio and surround sound are both audio technologies that aim to create an immersive listening experience. However, there are some key differences between the two:
Spatial Audio:
Spatial audio, as we’ve discussed, is a technology that uses motion sensors and advanced algorithms to simulate a three-dimensional sound experience. It is designed to create an immersive audio environment that goes beyond traditional stereo sound. Spatial audio takes into account factors such as head tracking, motion sensors, and personalized audio processing to provide a realistic representation of sound coming from various directions and distances. It aims to replicate the acoustics of a physical space, enhancing depth, and providing a more immersive audio experience.
One of the key features of spatial audio is the ability to accurately track the user’s head movements and adjust the audio accordingly. This creates a more dynamic and interactive listening experience, where sound sources appear fixed in space as you move your head, offering a highly immersive and realistic audio atmosphere.
Surround Sound:
Surround sound, on the other hand, refers to a multi-channel audio system that aims to reproduce audio from different directions around the listener using multiple speakers. It typically utilizes a configuration of speakers placed around the listening area, such as front, rear, and center speakers, to create a sense of sound coming from different directions. The most common surround sound configurations are 5.1 and 7.1, which consist of five or seven main speakers and a subwoofer for low-frequency sounds.
Surround sound technology has been widely used in home theaters, cinemas, and gaming systems. It provides an immersive audio experience by distributing audio through multiple speakers to create a sense of sound movement and realism. However, it is important to note that surround sound is typically optimized for a fixed listening position and may not provide the same level of dynamic head tracking and personalized audio processing as spatial audio.
While both spatial audio and surround sound aim to create an immersive audio experience, spatial audio offers more dynamic and personalized capabilities by adapting to the user’s head movements and providing a more realistic representation of sound in a three-dimensional space.
Now that we understand the differences between spatial audio and surround sound, let’s address some frequently asked questions about spatial audio.
