Being able to be there without being there, Sony has developed a real-time live broadcast technology for surreal stereo surround sound.
CTOnews.com, January 25, Sony recently announced that it has developed a real-time live broadcast technology with fully object-based stereo surround sound. In addition, Sony has also expanded the application of "360 live sound", a music experience that allows users to immerse themselves in a three-dimensional sound field.
Sony said that while live broadcasting is favored because of its convenience and freedom from location and movement restrictions, how to achieve a sense of experience like being there has always been a challenge. Sony has upgraded its self-developed 360 stereo surround sound technology to achieve real-time transmission of 3D sound and video based on "360 live sound effects", allowing users to experience the realism of enjoying live performances or concerts while not on the scene.
▲ 360Live Acoustics it is reported that 360Live Acoustics has improved the creative environment and developed a real-time encoder to provide live effects and sound quality for artists and sound engineers. In order to create a spatial music experience, the sound engineer first assigns location information to each sound source, such as human voice, guitar and drum, and arranges them in a spherical space. Sony has developed a new "360 Live Sound" creation tool for real-time transmission to improve the sound engineer's creative environment. With this tool, sound engineers can freely and instantly arrange sound sources and create three-dimensional sounds as expected.
In addition, in order to send music to the server and transmit it to users, audio data needs to go through a compression process, including location information, but it takes a certain amount of processing time to maintain high sound quality. Therefore, Sony has developed its own sound quality processing algorithm to achieve on-the-spot effects, which is essential for live broadcasting. In addition, using the object-based spatial audio technology of "360 live sound effect", the amount of information (bit rate) given to each sound source (object) can be automatically optimized without reducing the hearing quality. It can realize real-time live broadcast synchronized with video by compressing audio data in a short time.
CTOnews.com learned that Sony and American software company Streamsoft Inc. Co-developed App of "360Live Audio Live" (App), which aims to bring users an excellent experience of real-time transmission. After using this App with headphones, users can enjoy a new live entertainment experience.
The App supports Android and iOS smartphones and tablets and is suitable for any type of headset. If you use the "360 live sound" certified headphones provided by Sony or Audio-Technia, you can also optimize your experience by adjusting the personal features in the dedicated App.
In addition, the App is equipped with a real-time chat function, which makes the real-time communication between the artist and the audience, the audience and the audience a reality, so that the online audience can also experience it in person.
