Patent number: 11343631Abstract: In processing a multi-channel audio signal having at least three original channels, first and second downmix channels derived from the original channels are provided. For a selected original channel of the original channels, channel side information are calculated such that a downmix channel or a combined downmix channel including the first and second downmix channels, when weighted using the channel side information, results in an approximation of the selected original channel. The channel side information and the first and second downmix channels form output data to be transmitted to a low-level decoder, which only decodes the first and second downmix channels, or to a high-level decoder, which provides a full multi-channel audio signal based on the downmix channels and the channel side information.Type: GrantFiled: August 23, 2019Date of Patent: May 24, 2022Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Juergen Herre, Johannes Hilpert, Stefan Geyersberger, Andreas Hoelzer, Claus Spenger
