Abstract: An apparatus for generating one or more audio output channels from one or more audio signals is provided. The apparatus comprises a gain determiner configured to generate or to receive gain information, wherein the gain information indicates for each audio signal of at least one audio signal of the one or more audio signals how to attenuate or how to amplify said audio signal depending on a position associated with said audio signal and a reference position. Moreover, the apparatus comprises a signal generator configured to generate the one or more audio output channels from the one or more audio signals by attenuating or amplifying at least one of the one or more audio signals depending on the gain information.

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.

Abstract: An apparatus for generating a separated audio signal from an audio input signal is provided. The audio input signal includes a target audio signal portion and a residual audio signal portion. The residual audio signal portion indicates a residual between the audio input signal and the target audio signal portion. The apparatus includes a source separator, a determining module and a signal processor. The source separator is configured to determine an estimated target signal which depends on the audio input signal, the estimated target signal being an estimate of a signal that only includes the target audio signal portion. The determining module is configured to determine one or more result values depending on an estimated sound quality of the estimated target signal to obtain one or more parameter values.
