Personalized spatial audio tailors immersive auditory experiences to individual listeners. Through binaural audio and head-related transfer functions, it creates a 3D soundscape that simulates real-world acoustic cues. Over-ear headphones and in-ear earbuds optimized for this technology deliver precise positional cues, enhancing music listening, gaming, and movie experiences. Personalized spatial audio also has applications in AR, immersive experiences, and communication, where location-based audio enhances engagement and clarity.
