A digital audio encoder receives PCM encoded audio information and encodes it with first and second types of digital audio coding, the encoded audio information having self-contained data units, wherein corresponding pairs of self-contained data units encoded with the first type and second type of digital audio coding represent the same underlying audio information. A decoder receives the first and second audio information and an error signal indicating the detection of errors and omissions in the first audio information. The decoder provides a PCM audio output and/or an encoded audio output complying with said first type of digital audio coding based on either the first or second audio information depending on whether there are errors or omissions in the first audio information.
