Abstract
A method of audio processing includes generating a detection score based on the partial loudnesses of a reference audio signal, extracted audio objects, extracted bed channels, a rendered audio signal and a channel-based audio signal. The detection score is indicative of an audio artifact in one or more of the audio objects and the bed channels. The extracted audio objects and extracted bed channels may be modified, in accordance with the detection score, to reduce the audio artifact.
