  • Publication number: 20160142847
    Abstract: An apparatus for generating one or more audio output channels is provided. The apparatus includes a parameter processor for calculating output channel mixing information and a downmix processor for generating the one or more audio output channels. The downmix processor is configured to receive an audio transport signal including one or more audio transport channels, wherein two or more audio object signals are mixed within the audio transport signal, and wherein the number of the one or more audio transport channels is smaller than the number of the two or more audio object signals. The audio transport signal depends on a first mixing rule and on a second mixing rule. The first mixing rule indicates how to mix the two or more audio object signals to obtain a plurality of premixed channels. Moreover, the second mixing rule indicates how to mix the plurality of premixed channels.

  • Publication number: 20160064006
    Abstract: An audio decoder is proposed for decoding a multi-object audio signal including a downmix signal X and side information PSI. The side information includes object-specific side information PSIi for an audio object si in a time/frequency region R(tR,fR), and object-specific time/frequency resolution information TFRIi indicative of an object-specific time/frequency resolution TFRh of the object-specific side information for the audio object si in the time/frequency region R(tR,fR). The audio decoder includes an object-specific time/frequency resolution determiner 110 configured to determine the object-specific time/frequency resolution information TFRIi from the side information PSI for the audio object si. The audio decoder further includes an object separator 120 configured to separate the audio object si from the downmix signal X using the object-specific side information in accordance with the object-specific time/frequency resolution TFRIi.
