This type of blank is designed for use in consumer-market standalone audio CD recorders which hit the market about 15 years ago. Example: Philips CDR770. I am not aware of any such equipment being produced in a long, long time.
The difference from a “computer” blank is a flag (called the Disc Application Code) in the pregroove (the spiral groove which is stamped into the CD-R plastic at time of manufacturer) which identifies it as properly licensed for use in such equipment.
The distinction between “audio” and “computer” was designed to force owners of standalone audio CD recorders to pay more for the blanks, with the difference supposedly designed to compensate for lost royalties.
A computer CD burner does not care at all about this, and will use either “data” or “music” discs for whatever application you choose.
Standalone audio CD recorders designed for professional use (e.g. TASCAM, Marantz, HHb) also do not care, and will use any blanks you throw at them.
