The physical intangibleness of the compact disc (CD) and the high-quality, compact digital audio (CD-Audio) format have made these discs a favorite among audiophiles and music collectors. CDs are made up of a plastic coating that surrounds a metal substrate. The coating is an insulator, so when the CD is played, the metal vibrates and creates sound waves.
Because of this vibration, CDs cannot store large amounts of data like computer memory can. This limitation has led to the development of the CD-Audio format, which uses digital encoding techniques to store music on a CD-R or CD-RW disc.

Unlike regular CDs, which hold around 80 minutes of music, a CD-Audio disc can store up to 24 hours’ worth of music. This extra space is used to store high-resolution audio data that has been digitally encoded using bitonal compression.
Bitonal compression reduces the amount of data that needs to be stored by encoding each sample of audio as two adjacent bit values instead of one value. This results in increased resolution and better sound quality than traditional compressed formats like MP3 or AAC.
To play a CD-Audio disc, you will need a compatible player and an ISO 9660 Level 1
