Channel coding is very important in order to obtain high density recording and high reliability at the same time. Several new channel codes are developed for the improvement of digital audio recordings. In this paper, the fundamental parameters for the evaluation of channel codes are described, and several conventional codes are explained with the application to the present digital audio systems. In comparison to those, new codes are discussed. One of the new codes is applied to the format of professional digital audio recorders. The other is applied to Compact Disc Digital Audio Systems.
