Immersive, Cinematic Experience in Space-Constrained Applications
TI's Spatial Audio technology delivers an immersive, cinematic sound experience in smartphones, tablets, laptops, sound bars, and docking stations. Spatial Audio distributed sound processing coupled with loudspeaker array technology uses a combination of techniques to manipulate sounds in 3D space:
- Sound beamforming
- Cross talk cancellation
- Head Related Transfer Function (HTRF)
Easy-to-use tools allow you to quickly deploy Spatial Audio technology across your entire product portfolio from smartphones to sound bars with 2 to 16 speakers.
