An Apparatus For Providing A Processed Audio Signal, A Method For Providing A Processed Audio Signal, An Apparatus For Providing Neural Network Parameters And A Method For Providing Neural Network Parameters

Abstract: The invention describes an apparatus for providing a processed audio signal on the basis of an input audio signal, wherein the apparatus is configured to process a noise signal, or a signal derived from the noise signal, using one or more flow blocks, in order to obtain the processed audio signal, wherein the apparatus is configured to adapt a processing performed using the one or more flow blocks in dependence on the input audio signal and using a neural network. The invention further describes an apparatus for providing neural network parameters for an audio processing, wherein the apparatus is configured to process a training audio signal, or a processed version thereof, using one or more flow blocks in order to obtain a training result signal, wherein the apparatus is configured to adapt a processing performed using the one or more flow blocks in dependence on a distorted version of the training audio signal and using a neural network; wherein the apparatus is configured to determine neural network parameters of the neural networks, such that a characteristic of the training result audio signal approximates or comprises a predetermined characteristic. A method for providing a processed audio signal and a method for providing neural network parameters for an audio processing are also provided. The invention provides a trade-off between an effective modeling of a flow-based audio signal processing using neural networks and audio signal enhancement capabilities.
