From the perspective of ISRC (for the recording) and UPC (for the release) there is NO difference between a traditional recording versus a recording produced in part or entirely by AI.
Whether the recording was made by humans (composers, musicians, lyricists) or by AI, it is still a recording that needs to be identified with an ISRC Code. Whether a release (Single, EP, LP, etc.)
that the recording is published on contains AI material or not, it is still a release that needs to be identified with a UPC code.
There is NO difference in the coding required.
What may be changing in the future is the Embedding of META data into audio/video files. There is discussion in the music industry to make disclosure of AI use a standard. While this PRESENTLY is not required, it may soon become a standard to notate inside the audio/video file if or to what extent AI was involved in the making of the recording. Again, at this time, that is
not practice. Files continue to be embedded with regular META data as always.
