摘要： A calculation unit for a sound system comprises input means, a processor and output means. The input means have the purpose to receive an audio stream to be reproduced using the sound system. The output means has the purpose to control the sound system based on a first and a second plurality of individual audio signals. The processor is configured to calculate the first plurality of audio signals such that beamforming is performed by the array and to calculate the second plurality of individual audio signals to perform, using the sound system, direct sound suppression such that sound is canceled towards a listening direction. Furthermore, the processor filters at least the second plurality using a second passband characteristic comprising a second portion of the entire frequency range.

摘要： An apparatus for generating four or more audio output signals has a panning gain determiner and a signal processor. The panning gain determiner is configured to determine a proper subset from a set of five or more loudspeaker positions, so that the proper subset has four or more of the five or more loudspeaker positions. Moreover, the panning gain determiner is configured to determine the proper subset depending on a panning position and on the five or more loudspeaker positions, and to determine a panning gain for each of the four or more audio output signals by determining the panning gain depending on the panning position and on the four or more loudspeaker positions of the proper subset. The signal processor is configured to generate each of the four or more audio output signals depending on the panning gain for the audio output signal and on an audio input signal.

The metadata decoder (110) is configured to generate one or more reconstructed metadata signals, so that each of the one or more reconstructed metadata signals comprises the first metadata samples of one of the one or more compressed metadata signals and further comprises a plurality of second metadata samples. Moreover, the metadata decoder (110) is configured to generate each of the second metadata samples of each reconstructed metadata signal of the one or more reconstructed metadata signals depending on at least two of the first metadata samples of said reconstructed metadata signal. Moreover, the apparatus (100) comprises an audio channel generator (120) for generating the one or more audio channels depending on the one or more audio object signals and depending on the one or more reconstructed metadata signals. Furthermore, an apparatus for generating encoded audio information comprising one or more encoded audio signals and one or more compressed metadata signals is provided.

摘要： An apparatus for generating a plurality of audio channels for a first speaker setup is characterized by an imaginary speaker determiner, an energy distribution calculator, a processor and a renderer. The imaginary speaker determiner is configured to determine a position of an imaginary speaker not contained in the first speaker setup to obtain a second speaker setup containing the imaginary speaker. The energy distribution calculator is configured to calculate an energy distribution from the imaginary speaker to the other speakers in the second speaker setup. The processor is configured to repeat the energy distribution to obtain a downmix information for a downmix from the second speaker setup to the first speaker setup. The renderer is configured to generate the plurality of audio channels using the downmix information.
