The device has a multi-channel decoder (11) to make more than two multi-channels available from a multi-channel representation. A headphone signal processor (12) processes a headphone signal, in order to produce an uncoded stereo signal with an uncoded first stereo channel (10a) and an uncoded second stereo channel (10b). A stereo coder (13) codes the first uncoded stereo channels, in order to receive a coded stereo signal (14). The stereo coder has a data rate for transferring the coded stereo signal being smaller than a data rate for transferring the uncoded stereo signal. An independent claim is included for a method for producing a coded stereo signal of an audio piece or an audio data stream with a first stereo channel and a second stereo channel from a multi-channel representation of the audio piece or audio data stream, and a computer program. |
