An audio processor for providing loudspeaker signals on the basis of input signals, like channel signals and/or object signals, obtains an information about the position of a listener and an information about the position of a plurality of loudspeakers, or sound transducers. The audio processor selects one or more loudspeakers for a rendering of the objects and/or of the channel objects and/or of the adapted signals, derived from the input signals. The selection depends on the information about the position of the listener and about the positions of the loudspeakers and takes into consideration the information about one or more acoustic obstacles. The audio signal processor renders the objects/channel objects/adapted signals derived from the input signals, in dependence on the information about the position of the listener and about positions of the loudspeakers, in order to obtain the loudspeaker signals, such that a rendered sound follows a listener.

Audio processor and a method considering acoustic obstacles and providing loudspeaker signals

An audio processor configured for generating, for each of a set of one or more loudspeakers, a set of one or more parameters, which determine a derivation of a loudspeaker signal to be reproduced by the respective loudspeaker from an audio signal, based on a listener position and loudspeaker position of the set of one or more loudspeakers. The audio processor is configured to base the generation of the set of one or more parameters for the set of one or more loudspeakers on a loudspeaker characteristic of at least one of the set of one or more loudspeakers.

A soundbar includes a housing, at least two transducers of a first group and at least one transducer of a second group. The at least two transducers of the first group are arranged at the front side of the housing and configured to emit sound in a first direction in accordance with two first audio signals so as to reproduce a two dimensional sound field. The at least one transducer of a second group is arranged at second side of the housing and configured to emit sound in a second direction in accordance with a second audio signal such that the sound emitted by the at least one transducer of the second group reaches a predefined listener's position in a reflected manner to extend the two dimensional sound field in a height direction. The reflection reflecting the sound emitted by the at least one transducer of the second group has an order of at least two.

In an apparatus and a method for stripping/pushing out a punched grid and for ejecting a blanked part from a die in a precision blanking press, the force of stripping/pushing out and ejection can be adjusted independent of the knife-edged ring force and the counterstay counteracting force while reducing the mass of the knife-edged ring and counterstay pistons, increasing the stripping/pushing and ejection speeds, and at the same time simplifying the hydraulic circuit.
