The ISO/IEC 14496-3:2009/Amd.4:2013 standard is a crucial amendment to the original ISO/IEC 14496-3, which itself forms part of the MPEG-4 suite of standards designed for efficient coding and storage of audio and visual information. This Amendment No. 4 introduces new levels of efficiency and quality in the encoding of Audio Visual Objects (AVOs) specifically focusing on enhancements to Advanced Audio Coding (AAC). The amendment updates the specification to include new profiles, tools, and parameters that provide improved performance for AAC files. These modifications aim at addressing recent technological advancements while maintaining compatibility with existing systems, thus enabling broader application across various digital media platforms such as streaming services, mobile devices, and broadcast networks.
The inclusion of these enhancements not only boosts the quality and efficiency of audio content but also provides flexibility in implementation, allowing developers to optimize AAC encoding for different scenarios. This update is significant for industries relying on high-quality audio compression technology, enhancing user experience through more efficient data transmission and storage solutions.
