Spatial Audio: The Immersive, 3D Sound Technology Bringing Concert Halls into Your Headphones
-
Spatial audio aims to create an immersive, 3D-like listening experience by using psychoacoustics to simulate sound coming from different directions.
-
Binaural rendering transforms spatial audio soundtracks into stereo audio that tricks your brain into perceiving distinct sounds originating from around you.
-
Head-related transfer functions (HRTFs) are unique to each person and allow for more personalized, realistic spatial audio when used for binaural rendering.
-
Artists can create spatial audio by using virtual studio software to simulate mixing tracks in high-end Dolby Atmos production studios.
-
Streaming services have to balance optimized spatial audio mixes for physical surround sound systems and binaural renders for headphones.
