Abstract

A device for generating an encoded stereo signal from a multi-channel representation includes a multi-channel decoder generating three of more multi-channels from at least one basic channel and parametric information. The three or more multi-channels are subjected to headphone signal processing to generate an uncoded first stereo channel and an uncoded second stereo channel which are then supplied to a stereo encoder to generate an encoded stereo file on the output side. The encoded stereo file may be supplied to any suitable player in the form of a CD player or a hardware player such that a user of the player does not only get a normal stereo impression but a multi-channel impression.
