As consumers demand more immersive and seamless experiences, Spatial Audio has become a key technology in a broad range of applications.
Overview
When we listen to sound through headphones or TWS earbuds, our brains are denied much of the key information they use to interpret the world. As a result, sound, even surround sound, seems to come from inside the head. Spatial audio recreates the missing information – like the exact position of the sound source or the design of the listening room – in order to create a more realistic, immersive experience. 3D rendering on its own externalizes your perception of where audio is coming from, bringing it out of your head and into the world around you. But the brain is a very sensitive instrument and interprets subtle differences between reflections, reverberations, and how it all interacts with your ears. That’s why, for a truly realistic experience, you need to track head motion and know where the ears are located relative to the source of the sound.
- Stereo/Surround Sound
- Sound comes directionally but from a limited number of sources.
- The brain interprets sounds as coming from inside the head.
- The guitarist is inside your left ear.
- Spatial Audio
- The brain interprets the sound as coming from outside the head.
- Soundfield is externalized and fixed to the head.
- The guitarist is always at 10 o’clock.
- Spatial Audio + Head Tracking
- Soundfield is externalized and fixed in place as you move.
- The guitarist stays at the left of the virtual stage even as you dance and move.
CEVA’s RealSpace® is a complete spatial audio solution, combining proven best- in-class 3D rendering with precise head tracking to bring total immersion to any audio content in an easy-to-integrate package. Get out of your head and into the action with RealSpace®.
