Abstract

A digital audio signal is reproduced from a master medium (7) and stored in a digital storage medium (10, 90, 90') at a specific first bit rate, after which it is read from the digital storage medium and recorded on a recording medium at a second bit rate. The digital audio signal, in the form of a first digital information signal having channel words of n data bits, is stored in a track (Ta.i) on the master medium. This signal is converted in an n-m demodulator (9, 15), the n-bit channel words being converted into m-bit information words, where n>m. After this the signal is stored in the digital storage medium (90, 90') as a second digital information signal. After read out from the storage medium (90, 90') the second digital information signal is converted into a third digital information signal, which substantially corresponds to the first digital information signal, in an m-n modulator (11, 36), in whcih the m-bit information words are reconverted into n-bit channel words. This enables the storage capacity of the digital storage medium to be reduced.
