摘要： A parameter transformer generates level parameters, indicating an energy relation between a first and a second audio channel of a multi-channel audio signal associated to a multi-channel loudspeaker configuration. The level parameter are generated based on object parameters for a plurality of audio objects associated to a down-mix channel, which is generated using object audio signals associated to the audio objects. The object parameters comprise an energy parameter indicating an energy of the object audio signal. To derive the coherence and the level parameters, a parameter generator is used, which combines the energy parameter and object rendering parameters, which depend on a desired rendering configuration.

摘要： A transmitter is disclosed for transmitting an audio signal. The transmitter comprises an input terminal (1) for receiving the audio signal, a 1-bit A/D converter (4) for A/D converting the audio signal so as to obtain a bitstream signal, a prediction unit (10) for carrying out a prediction step on the bitstream signal so as to obtain a predicted bitstream signal, a signal combination unit (42) for combining the bitstream signal and the predicted bitstream signal so as to obtain a residue bitstream signal, data compression means (154) for data compressing the residual bitstream signal so as to obtain a data compressed residual bitstream signal, and transmission means for applying the data compressed residual bitstream signal to a transmission medium (Figure 1 and 5). Further, a corresponding recording apparatus (Figure 1 and 4) is disclosed.
In addition, another embodiment (Figure 7) for converting the residue bitstream signal into an audio signal is disclosed, as well as a reproducing apparatus (Figure 9) and a receiver apparatus (Figure 10) comprising the other embodiment.
