NSYNC · Neural Sphere Audio

Neural Sphere Audio.
Sound shaped around you.

Neural Sphere Audio models human auditory perception to render discrete multichannel audio as a perceived three-dimensional auditory sphere. NSYNC pairs this rendering with AI XPHERE source separation and placement, and intelligent hearing protection across source types.

It runs inside media and content services, inside desktop and mobile applications, inside listening devices, and inside embedded audio processors — the same engine, adapted to the compute available to it.

“Sphere” describes the perceived listening space, not an input format or Ambisonics / spherical-harmonic encoding. Full-sphere rendering extends placement above and below the listener in supported configurations.

Configuration family: Neural Sphere 7.1 · Neural Sphere 7.1.4 · Neural Sphere 7.1.4.4 · Neural Sphere 7.1.8.8. Input support and available rendering modes depend on the product and target platform. Explore the architecture and channel definitions.

Three core capabilities.

01 · RENDER

Neural Sphere Audio

Render existing native/discrete multichannel sources into a perceived 3D auditory sphere. Playback paths are configured for stereo speakers, earphones and headphones, with binaural rendering for two-ear listening.

02 · SEPARATE & PLACE

AI XPHERE

Separate mono or stereo audio sources in real time, then generate and place the estimated components within a Sphere Audio scene for surround and three-dimensional playback.

03 · PROTECT

Intelligent hearing protection

A complementary processing layer designed to support hearing protection across all source types, alongside native multichannel rendering or AI XPHERE.

XPHERE creates a new spatial arrangement from estimated components; it does not recover the original discrete mix. Supported playback paths and protection features are specified for each product.

Where the renderer runs

One engine.
Four places it works.

01
Media & Content
