APPARATUS AND METHODS FOR AUDIO ENCODING REPRODUCTION

摘要

An apparatus for encoding an audio signal is configured to receive audio components from at least one microphone located or directed to an audio source, and receive audio components from at least one further microphone. Either the further microphone is located at a position further away from the source than the position of the at least one microphone, or the further microphone is directed away from the source. The components received from the further microphone comprise fewer audio components than the components received from the at least one microphone. The apparatus is configured to encode the components received from the at least one microphone as a first scalable encoded signal layer, encode the components received from the further microphone as a second scalable encoded signal layer, and combine the first and second layers to form a third scalable encoded signal layer.
