Audio coding using downmix
Oliver Hellmuth,Juergen Herre,Leonid Terentiev,Andreas Hoelzer,Cornelia Falch,Johannes Hilpert +5 more
TL;DR: In this article, an audio decoder for decoding a multi-audio-object signal having an audio signal of a first type and an audio signals of a second type encoded therein is described.

Multi-channel synthesizer and method for generating a multi-channel output signal
Herre Juergen,Sascha Disch,Hilpert Johannes,Christian Ertel,Andreas Hoelzer,Claus-Christian Spenger +5 more
TL;DR: In this article, a multi-channel synthesizer includes a post processor for determining post processed reconstruction parameters or quantities derived from the reconstruction parameter for an actual time portion of the input signal.

TL;DR: In this paper, a method for decoding a multi-audio-object signal having an audio signal of a first type and a second type encoded therein is described, the method comprising computing a prediction coefficient matrix C based on the level information (OLD); and up-mixing the down-mix signal based on prediction coefficients to obtain a first upmix audio signal approximating the audio signal from the first type, and/or a second up-mixed audio signal by the second type.
