What do the ISRC Handbook and CISAC say each identifier identifies, and when does an edit, remix, stem, remaster or clip of a music recording need its own ISRC?
The ISRC Handbook (2021, CC BY-ND 4.0) ties an ISRC to a recording, not its encoding: new ISRCs for edits, covers, live versions, separately released stems and promo clips; none for codec changes, non-creative remasters or length changes under 10 seconds without creative input; MIDI files get none. CISAC's ISWC identifies the musical work by title and creators, not its recordings or uses. They are different keys for the same cue.
