  • Publication number: 20230419982
    Abstract: An apparatus for providing a sequence of output gains, wherein the sequence of output gains is suitable for attenuating a background signal of an audio signal is provided. The apparatus comprises a signal characteristics provider configured to receive or to determine signal characteristics information on one or more characteristics of the audio signal, wherein the signal characteristics information depends on the background signal, wherein the signal characteristics information comprises a sequence of input gains which depends on the background signal and on a foreground signal of the audio signal. Moreover, the apparatus comprises a gain sequence generator configured to determine the sequence of output gains depending on the sequence of input gains.

  • Publication number: 20230395079
    Abstract: There are described techniques (e.g. methods and systems) for signal-adaptive remixing of separated audio sources. A system may comprise: a source separation block estimating, from an input signal, a target signal and at least one residual signal to be subsequently remixed according to at least one remixing gain variable along the discrete succession; a control block configured to determine, for a determined current time instant or time slot, metrics on the target signal; and a temporal context block determining temporal context information based on metrics on the target signal. The control block may generate a remixing gain associated to the determined current time instant or time slot by considering: the metrics in the determined current time instant or time slot; and the temporal context information.
