    摘要: The invention proposes extracting one or more speech signals (151-154) as well as one or more ambient signals (131) from sound signals captured by microphones, wherein each of the speech signals corresponds to a different speaker. The invention proposes to transmit both the one or more speech signals (151-154) and the one or more ambient signals (131) to a rendering side, as opposed to sending only speech signals. This enables to reproduce the speech and ambient signals in a spatially different way at the rendering side. By reproducing the ambient signals a feeling of “being together” is created. In an embodiment, the invention enables reproducing two or more speech signals spatially from each other and from the ambient signals so that speech intelligibility is increased despite the presence of the ambient signals.

    摘要: A method is described, wherein multiple input signals are subjected to a combination process of adaptive beamforming and adaptive echo cancelling, and wherein for each of the input signals an individual processing history of adaptive echo cancelling data is kept and combined with current adaptive beamforming data. Accordingly an audio processing device is described which comprises at least one parallel acoustic paths for providing respective inputs signals, the acoustic paths are connected in series to beamformer paths, and the device comprises an adaptive beamformer and an adaptive echo canceller for performing adaptive beamforming and adaptive echo cancelling respectively, whereby the adaptive echo canceller is provided with storage means for storing in relation to every input signal, individual processing histories of adaptive echo cancelling data for combination with current adaptive beamforming data. Both beamformer and echo cancelling techniques can be combined such that a reduced number of calculations results.

    摘要: A method for noise suppression is described, wherein noisy input signals in a multiple input audio processing device are subjected to adaptations and summed and wherein the noise frequency components of the noisy input signals in the summed input signals are estimated based on individually kept noise frequency components and on said adaptations. Advantageously the method may be applied if a spectral subtraction like technique is applied in a multi input beamformer. Only one spectral frequency transformation is necessary, which reduces the number of necessary calculations.

    摘要: A sound reinforcement system includes several microphones, a microphone beamformer coupled to the microphones, adaptive echo compensator (EC) coupled to the microphone beamformer for generating an echo compensated microphone signal, and several loudspeakers coupled to the adaptive EC. An adaptive loudspeaker beamformer is coupled between the adaptive EC and the loudspeakers for shaping the directional pattern of the loudspeakers. The adaptive loudspeaker beamformer creates a beam pattern which is capable of creating a “null” in the direction of speaker(s) such that howling is effectively prevented.
