Abstract
A method for decoding a multi-audio-object signal having audio signals of first and second types encoded therein, the multi-audio-object signal having a downmix signal and side information having level information of the audio signals of the first and second types in a first predetermined time/frequency resolution, the method including computing a prediction coefficient matrix C based on the level information; and up-mixing the downmix signal based on the prediction coefficients to obtain a first and/or a second up-mix audio signal approximating the audio signals of the first and second types, respectively, wherein up-mixing yields the first and/or second up-mix signals Sand Sfrom the downmix signal d according to a computation representable by with '1' denoting—depending on the number of channels of d—a scalar, or an identity matrix, and Dbeing a matrix uniquely determined by a downmix prescription according to which the audio signals of the first and second types are downmixed into the downmix signal, and which is also included by the side information, and H being a term independent from d.
