  • Method of performing measurements by means of an audio system comprising passive loudspeakers
    Patent number: 8270620
    Abstract: The present invention relates to a method of performing measurements by means of an audio system comprising passive loudspeakers, whereby said measurements loudspeakers for producing sound and at least one of said loudspeakers for measuring said sound. The present invention further relates to an audio system comprising N passive loudspeakers, wherein said audio system further comprises an output stage where each output acts as a combined output channel and a measurement input.

  • Signal processing unit
    Patent number: 7403625
    Abstract: The invention relates to a signal processing unit including an input for receiving an audio signal, and an early pattern generator connected to the input, for defining a predefined early pattern generation. The early pattern generator establishes an output having N directional components which are added to form a signal having N directional components. When representing each source output in a direction containing representation both directionality of the individual sound sources as well as the resulting directionality of the excited sound propagation may be contained and processed in a simple processing algorithm.
