Sony's Sound Building Blocks 360 Spatial Audio Technology Application

Sound Building Blocks™ is one of Sony's 360-degree spatial audio technologies that enables a fully immersive experience by transforming stereo content into natural, realistic, and captivating 360 spatial sound. The advanced spatial audio system equipped with Sony's Sound Building Blocks™ technology offers a new experience where every passenger feels as if they are at the center of a concert. The technology is not limited by vehicle size, allowing for flexible placement of imaginary audio sources that provide a wide and stable sweet spot, ensuring optimal experience for every seat. It features real-time control of the position of imaginary audio sources and the shape of the sound field with minimal resource requirements, making it more DSP-friendly. It also natively supports object-based audio formats such as 360RA and Dolby Atmos. Unique advantages include: 1) The use of three proprietary Sony technologies: separation of main melody and ambient sound, three-dimensional sound field reconstruction, and imaginary audio source rendering. 2) Achieving spatial audio effects with fewer hardware requirements compared to the original need for 20-30 speakers. 3) Real-time synthesis and continuous movement control of imaginary audio sources in three-dimensional space, thanks to Sony's unique algorithm optimizations. Application scenarios include music playback, audio-visual entertainment, and cockpit audio interaction.
