In General XR News

December 22, 2022 – sony corporation recently announced that it has created an object-based full spatial sound real-time live distribution technology. In addition, the company has expanded the range of support for its ‘360 Reality Audio’ platform, a music experience that allows users to immerse themselves in a three-dimensional sound field.

Sony stated that it has developed its proprietary 360 Spatial Sound technology, which enables real-time distribution of three-dimensional sound and video with 360 Reality Audio, so that users can experience the reality of enjoying a live performance or concert at the same time. without being there. .

360 Reality Audio uses Sony’s object-based spatial sound technology to deliver an immersive music experience that feels like being at a live concert. 360 Reality Audio makes it possible for artists and music creators to create a 360-degree music experience by mapping sound sources like vocals, choirs, and instruments with positional information to suit their creative and artistic purpose. When listeners play the resulting content, they can enjoy a musical experience that immerses them in sound from all directions as intended by the content creator, according to Sony.

The company claims that 360 Reality Audio has helped improve the production environment, with Sony developing a real-time encoder that provides real-time performance and sound quality for artists and sound engineers. To create a spatial music experience, sound engineers first assign positional information to each sound source, such as vocals, guitars, and drums, and arrange it in a spherical space. Sony has also developed a new 360 Reality Audio production tool for real-time distribution to improve the production environment for sound engineers. With this tool, engineers can freely and instantly position sound sources, and create sound with a three-dimensional effect as intended, according to the company.

In addition, Sony has developed its own sound quality processing algorithm to achieve real-time performance, which is important for live distribution. The company claimed that by taking advantage of the fact that 360 Reality Audio is an object-based spatial audio technology, the amount of information (bit rate) given to each sound source (object) is automatically optimized, without reducing hearing quality. This enables real-time delivery synchronized with the video by compressing the audio data for a short period of time.

Sony jointly developed ‘360 Reality Audio Live’ with American software company Streamsoft Inc., an application that allows users to enjoy real-time distribution of 360 Reality Audio. The app allows users to enjoy live entertainment with immersive audio using their own headphones and is equipped with a real-time chat feature that enables real-time communication between performers and viewers, helping to enhance the sense of presence. virtual as if they were participating on the spot.
