  • Apparatus and method for processing a multichannel audio signal
    Patent number: 11929089
    Abstract: An apparatus for processing a multichannel audio signal has a plurality of channel signals. The apparatus performs a time scale modulation of the multichannel audio signal and has a phase adaptor and a separator. The phase adaptor provides a processed signal by modifying a phase of a signal based on a combination of the channel signals. The separator provides separated signals based on the processed signal. A corresponding method is provided.

  • Device and method for volume control
    Patent number: 10389322
    Abstract: A device for volume control for at least two audio sources includes a loudness analyzer and a volume regulator. The loudness analyzer is configured to analyze an audio signal of the first one and of the second one of the two audio sources over a time period, to determine a first and a second loudness value, respectively, as a function thereof, and to store same while associating them with the first and the second audio source. The volume regulator is configured to adapt the audio signal of the currently selected first and/or second one of the two audio sources in accordance with the corresponding first and/or second loudness value.
