  • Patent number: 8363847
    Abstract: An aliasing correction in a wave field synthesis system is achieved by ascertaining the aliasing filter property specific for a virtual source. This aliasing filter property, which, for example, may be the aliasing frequency is ascertained by help of the source position information. This aliasing filter property is used for an adaptive anti-aliasing filter for adaptive filtering of the audio signal associated with the source or the component signals associated with the source.

  • Patent number: 8189824
    Abstract: In a reproduction area where there are at least three directional groups, each of which has speakers, triggering of the speakers is achieved in that a source path from a first directional group position to a second directional group position is initially obtained along with movement information for the source path. Subsequently, a source path parameter is calculated for different points in time on the basis of the movement information, the source path parameter indicating a position of an audio source on the source path. In addition, a path modification command is received to define a compensation path to the third directional zone, a value of the source path parameter further being stored at a location where the compensation path deviates from the source path, and being used, along with a compensation parameter, for calculating weighting factors for the speakers of the three directional groups.

  • Patent number: 8160280
    Abstract: In a reproduction environment, speakers are grouped in directional groups, wherein the directional groups overlap with respect to the associated speakers so that speakers are present which have a speaker parameter having different values for the first directional group and the second directional group. A controller for controlling a plurality of speakers has a provider for providing a source position of an audio source, wherein the source position is located between the first directional group position and the second directional group position. The apparatus further has a calculator for calculating a speaker signal for the at least one speaker, based on the first parameter value for the speaker parameter and based on the second parameter value for the speaker parameter.

  • Patent number: 7283197
    Abstract: A device for synchronizing an audio signal with a film comprising frames having imprinted time codes. A detector detects the imprinted time code for the sequence of frames to obtain a detected sequence of time codes. A time code generator generates a sequence of synthesis time codes based on an initial value. A decoder decodes a time code of the detected sequence of time codes obtain the initial value. A comparator compares a detected time code and a corresponding synthesis time code and, when a phase deviation is found to be above a deviation threshold value, a time code manipulator manipulates the synthesis time code for this frame in so far that it is changed with regard to its temporal length. An audio processor provides the samples of the audio signal associated with this frame in a time-controlled way in response to a detection of the synthesis time code for a frame.
