The Universal Product Code (UPC) is a barcode symbology globally used for tracking trade items in stores.
The International Standard Recording Code (or ISRC code) is a unique identification system for sound recordings and music video recordings. Each ISRC code identifies a specific unique recording and can be permanently encoded into a product as a kind of digital fingerprint.
But enough with technicalities. If you don’t have these codes for your song - worry not! Corite will generate them automatically.
