Retrieved from ” https: There was a debate over the use of bit or bit quantization. The standard is defined in the Red Book, one of a series of Rainbow Books that contain the specifications for all Compact Disc formats. This system could store bit samples with some correction, or bit samples with almost no error correction. Although rarely used, the specification allows for discs to be mastered with a form of emphasis, the second edition of IEC was published in and it cancels and replaces the first edition, amendment 1 and the corrigendum to amendment 1.
