Overview
ISO/IEC 23003-1:2007/Amd 4:2017 is an important international standard published by ISO and IEC that enhances MPEG audio technologies, specifically focusing on MPEG Surround. This amendment introduces reference software for the MPEG Surround extension aimed at supporting 3D audio applications. It serves as a key advancement in the field of information technology and audio coding, enabling more immersive and realistic spatial audio experiences.
This amendment builds upon the original Part 1 standard of the MPEG Surround series by providing updated tools and resources that facilitate the implementation and development of 3D audio solutions. Its technical development is overseen by ISO/IEC JTC 1/SC 29, a specialized committee dedicated to coding audio, pictures, multimedia, and hypermedia information.
