Identifying sound recordings and videos containing the same audio

In some cases, the same audio soundwave is used in both a sound recording and in a separate music video. In line with the ISRC rules the sound recording and the music video must have different ISRCs (see also Section A.9.6 of the ISRC Handbook, https://www.ifpi.org/wp-content/uploads/2021/02/ISRC_Handbook.pdf).

This also applies in cases where one audio soundwave is used as part of a sound recording resource and a music video resource. In such cases the sound recording would be represented by the audio resource file on its own, and the video would be represented by the same audio resource file plus a video resource file. Despite the fact that the sound recording and the video “contain” the same audio resource file, the sound recording and the video must have different identifiers. This is particularly important for immersive audio where resource files can have significant sizes (see also https://isrc.ifpi.org/downloads/ISRC_Bulletin_2022-01_Immersive_Recordings_and_Music_Video_Variants.pdf).
