Audio encoder with signal enhancement module, signal activity detector and active phase audio encoder, encoding 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 a signal activity detector, configured to obtain a signal activity information, using 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, 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, in dependence of the signal activity information. Furthermore, encoding methods, computer programs and bitstreams are disclosed.
