Audio encoder with signal enhancement module, active phase audio encoder and inactive phase audio encoder, audio decoder with mixer, encoding method, decoding method, computer program and bitstream

Abstract

Embodiments comprise an audio encoder for providing an encoded representation on the basis of an input audio signal, wherein the audio encoder comprises a signal enhancement module, configured to apply a noise reduction to the input audio signal, or to a processed version thereof, to obtain an enhanced audio signal, wherein the audio encoder comprises an active phase audio encoder, configured to provide the encoded representation on the basis of the enhanced audio signal, or a processed version thereof, wherein the audio encoder comprises an inactive phase audio encoder, configured to obtain a noise reduction information about the noise reduction applied to the input audio signal, or to the processed version thereof, by the signal enhancement module and to provide the encoded representation on the basis the noise reduction information, and / or wherein the inactive phase audio encoder is configured to provide the encoded representation on the basis of the enhanced audio signal, or a processed version thereof. Furthermore, a decoder with a mixer, encoding methods, computer programs and bitstreams are disclosed.
