Red book audio is also referred to as CD-DA (Compact Disc-Digital Audio). Introduced by Sony and Philips in 1980, the Red Book standard was simply designed to be a universal medium for distributing digitized music.

Data on a audio CD is organized into frames. Each frame contains up to 24 bytes of user data, synchronization, LECC (Logical Error Correction Code), and data for control and display. Frame are interleaved with other frames into a single, spiral so that scratches or defects will not destroy a single frame beyond correction. Rather, a scratch will destroy a small portion of many frames, all of which can be recovered in other frames.

A Red Book disc is divided into three areas: Lead In, Program, and Lead Out. Every track's location is recorded into the disc's TOC (Table of Contents) which is stored in the Lead In area of every disc. The Red Book CD was to become the template for which all other "book standards" were created.
