摘要：
An apparatus for adapting input audio information, encoding one or more audio objects, to obtain adapted audio information is provided. The input audio information comprises two or more input audio downmix channels and further comprises input parametric side information. The adapted audio information comprises one or more adapted audio downmix channels and further comprises adapted parametric side information. The apparatus comprises a downmix signal modifier (110) for adapting, depending on adaptation information, the two or more input audio downmix channels to obtain the one or more adapted audio downmix channels. Moreover, the apparatus comprises a parametric side information adapter (120) for adapting, depending on the adaptation information, the input parametric side information to obtain the adapted parametric side information.
