The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) jointly published Amendment 15 to ISO/IEC 14496-4:2004, titled "Information technology - Coding of audio-visual objects - Part 4: Compliance testing for oversampled lossless audio coding," on August 6, 2007. This amendment focuses on enhancing the standard for the efficient and effective compression of high-quality audio signals that operate at sampling rates significantly higher than those typically used in conventional audio systems.
The document introduces new methodologies for conducting consistency tests to ensure interoperability among various devices and software applications dealing with oversampled lossless audio coding. It aims to improve upon previous standards by providing detailed guidelines on how to implement these advanced coding techniques, which are crucial for maintaining the integrity of high-resolution sound recordings during digital transmission or storage.
By adopting Amendment 15, developers can better adhere to industry best practices and meet regulatory requirements related to audio technology. This update is particularly beneficial in industries where high-fidelity sound reproduction is essential, such as music production, broadcasting, and home entertainment systems.
