摘要： An apparatus for generating loudspeaker signals is provided. The apparatus comprises an object metadata processor (110) and an object renderer (120). The object renderer (120) is configured to receive an audio object. The object metadata processor (110) is configured to receive metadata, comprising an indication on whether the audio object is screen-related, and further comprising a first position of the audio object. The object metadata processor (110) is configured to calculate a second position of the audio object depending on the first position of the audio object and depending on a size of a screen, if the audio object is indicated in the metadata as being screen-related. The object renderer (120) is configured to generate the loudspeaker signals depending on the audio object and depending on position information. The object metadata processor (110) is configured to feed the first position of the audio object as the position information into the object renderer (120), if the audio object is indicated in the metadata as being not screen-related. The object metadata processor (110) is configured to feed the second position of the audio object as the position information into the object renderer (120), if the audio object is indicated in the metadata as being screen-related.

摘要： A method for processing an audio signal (504) in accordance with a room impulse response is described. The audio signal (504) is processed (502) with an early part of the room impulse response separate from a late reverberation of the room impulse response, wherein the processing (514) of the late reverberation comprises generating a scaled reverberated signal, the scaling (526) being dependent on the audio signal (504). The processed early part (506) of the audio signal (504) and the scaled reverberated signal are combined.

摘要： A method for processing an audio signal (400) in accordance with a room impulse response includes separately processing (402, 404, 406) the audio signal (400) with an early part of the room impulse response and with a late reverberation of the room impulse response or a synthetic reverberation, wherein processing (402, 404) the audio signal with the early part of the room impulse response comprises a convolution of the audio signal with a direct sound and early reflections of the room impulse response; combining (418) the audio signal (414) processed with the early part of the room impulse response and the audio signal (416) processed with the late reverberation of the room impulse response or with the synthetic reverberation; and determining a transition from the early part to the late reverberation in the room impulse response as a time when a correlation measure reaches a threshold. The correlation measure describes with regard to the room impulse response a similarity of a decay in acoustic energy including an initial state and of the decay in acoustic energy starting at a point in time, said point in time following the initial state over a predefined frequency range. The threshold is set dependent on the correlation measure for said point in time, said point in time being a time of a selected one of the early reflections in the early part of the room impulse response. The selected one of the early reflections is the first reflection.
