Spatial Sound
360° Spatial SoundHead-tracked 3D audio
Turn your head —
sound stays put.
360° Spatial Sound Solution
What is 360° Spatial Sound
Like moving through
a virtual 3D space.
Next-gen audio software that follows head movement with the device’s IMU sensor,
creating 3D sound all around the listener.
- 360°Sound from every direction
- IMUSensor-based head tracking
- Low LatencyFast on embedded devices
Head Tracking
Turn your head.
The sound doesn’t follow.
With tracking off, sound turns with your head and feels inside it.
With tracking on, sound stays in place — as if it’s really there.
Visual demo — no audio.
How It Works
Sensor to ear, in real time.
A spatial audio engine combining sensor head tracking and real-time binaural rendering.
- STEP 01IMU sensorSensors in earphones, headphones or phones read head yaw, pitch and roll
- STEP 02Head trackingTracks head movement and recalculates sound positions in real time
- STEP 03Binaural renderingBuilds the sound for each ear on the fly and plays it on earphones
Core Technology
Four technologies behind it.
Built on our own sound localization, reverb and crosstalk cancellation technology.
PAMS
Spreads multichannel audio across space for playback.
- Real-time dynamic playback using distance, direction and room information
- Applies head movement to the sense of space, naturally
- Deeper immersion in VR content
Core Technology
- rSIc — Sound Positioning and Movement (earphones)
- Reverb based on RTF (Room Transfer Function)
- Adaptive Volume Stabilization
