ISO/IEC 23003-1:2007/COR3:2010 is a technical corrigendum tied to MPEG audio technologies, specifically Information technology - MPEG audio technologies - Part 1: MPEG Surround - Technical Corrigendum 3. As a supporting reference to the parent document ISO/IEC 23003, it is relevant where engineering teams, test labs, and compliance reviewers need to track corrections that affect documented requirements or interpretation. ISO/IEC 23003-1:2007/COR3:2010 helps maintain alignment between technical documentation, verification activities, and procurement review when MPEG Surround work depends on the corrected text.

ISO/IEC 23003-1:2007/COR3:2010 standard overview

This corrigendum serves as a modifying document rather than a standalone technical specification. It is connected to the first edition of Part 1 in the ISO/IEC 23003 series and is intended to clarify, correct, or refine the published MPEG Surround text. In practice, that makes it useful during technical review, conformity assessment preparation, and document control, especially when teams must confirm that implementation notes, test plans, and engineering documentation reflect the corrected requirements associated with ISO/IEC 23003-1:2007/COR3:2010.

Applications of ISO/IEC 23003-1:2007/COR3:2010

Organizations may use this corrigendum when evaluating MPEG Surround-related products, software, codecs, or media processing systems that rely on accurate standard text. It is also relevant for laboratory evaluation, specification review, and supplier communication where a documented correction can affect operational consistency or test interpretation. In quality workflows, ISO/IEC 23003-1:2007/COR3:2010 can support engineering validation, regression testing, and controlled updates to compliance references used across development and verification teams.

Why ISO/IEC 23003-1:2007/COR3:2010 matters

Supporting documents such as this corrigendum help reduce implementation risk by ensuring that engineering teams work from the corrected version of the published requirements. That matters when organizations are preparing technical documentation, confirming product behavior, or managing conformity assessment evidence. Using ISO/IEC 23003-1:2007/COR3:2010 alongside the parent reference can improve test consistency, support procurement decisions, and strengthen technical compliance processes where accurate version control is essential.

• Corrigendum linked to the MPEG Surround technical framework in the ISO/IEC 23003 series.
• Useful for document control, technical review, and verification activities based on corrected published text.
• Supports testing workflows, compliance preparation, and engineering validation for related audio technology implementations.
• Relevant to procurement and conformity assessment when the corrected reference must be tracked accurately.
