Abstract
Parametric multichannel information is written onto a normal standard audio compact disc, e.g. in the user subchannels, so that the CD enables normal stereo reproduction with a normal reproduction device, or multichannel reproduction with a supplementary device which is easy to connect and which reads out both the stereo information and the parametric multichannel information from the audio CD actually conforming with the standard, and reconstructs more than two audio channels therefrom.
