  • Filter and method for informed spatial filtering using multiple instantaneous direction-of-arrival estimates
    Patent number: 10331396
    Abstract: A filter for generating an audio output signal includes a plurality of audio output signal samples based on two or more input microphone signals. The audio output signal and the two or more input microphone signals are represented in a time-frequency domain, wherein each of the plurality of audio output signal samples is assigned to a time-frequency bin of a plurality of time-frequency bins. The filter includes a weights generator being adapted to receive, for each of the plurality of time-frequency bins, direction-of-arrival information and weighting information. Moreover, the filter includes an output signal generator for generating the audio output signal.

  • Apparatus and method for providing an informed multichannel speech presence probability estimation
    Patent number: 9633651
    Abstract: An apparatus for providing a speech probability estimation is provided. The apparatus includes a first speech probability estimator for estimating speech probability information indicating a first probability on whether a sound field of a scene includes speech or on whether the sound field of the scene does not include speech. Moreover, the apparatus includes an output interface for outputting the speech probability estimation depending on the speech probability information. The first speech probability estimator is configured to estimate the first speech probability information based on at least spatial information about the sound field or spatial information on the scene.
