MP3Surround belongs to a new generation of coding technologies based on the “binaural cue coding”–technique, which transmit — different from the discrete transmission of 5.1-material — only a stereodownmix of the multichannel-signal together with a compact side information. From this signals the decoder generates a multi-channel signal with a spatial image similar to the spatial image of the original input signal. The stereodownmix is created from the multichannel-signal using a dynamic downmixing algorithm. MP3Surround also gives the opportunity to use a manually created downmix as sum signal for the decoder using the original spatial cues. This paper discusses the effects of differences between the manual downmix and the automatic downmix on the decoded surround-version.
