Fully embedded spatial audio rendering engine with precise head tracking to bring total immersion to any audio content

Ceva-RealSpace is a fully-embedded Spatial Audio solution combining precise 3D rendering and accurate, low-latency head tracking. RealSpace supports multiple system architectures, giving you the flexibility to render content directly on TWS earbuds, headphones, XR headsets, or speakers for the lowest latency. Or choose to render on mobile phones, gaming systems, or PCs and save BOM costs on the device. This means a great experience isn’t tied to a particular device ecosystem, content provider, or codec. Ceva-RealSpace powered earbuds and headphones can render any content in exceptional 3D. Pre-integrated on some of the top audio SoCs in the industry, Ceva-RealSpace helps you bring cutting-edge products to market faster and with less risk.

Across Consumer Electronics devices, users expect seamless, engaging, and immersive experiences. For headphones, earbuds and speakers, Spatial Audio, with 3D rendering and head tracking, is the key to providing experiences like:

  • Knowing exactly where an enemy’s footsteps are when gaming
  • Feeling part of the crowd when watching live sports
  • Hearing each musician in the band as if you were at a live concert
  • Merging the real and virtual worlds in XR


To better meet our customers’ needs, Ceva-RealSpace is available in three variants for different product types:
