APPARATUS AND METHOD FOR PROVIDING A MEASURE OF SPATIALITY ASSOCIATED WITH AN AUDIO STREAM

摘要

Apparatus for evaluating an audio stream, wherein the audio stream comprises audio channels to be reproduced at at least two different spatial layers, wherein the two spatial layers are arranged in a manner distanced along a spatial axis. The apparatus is configured to evaluate the audio channels of the audio stream so as to provide a measure of spatiality associated with the audio stream.
