Patent number: 11955131Abstract: An apparatus for encoding a multi-channel signal having at least three channels includes an iteration processor, a channel encoder and an output interface. The iteration processor is configured to calculate inter-channel correlation values between each pair of the at least three channels, for selecting a pair including a highest value or including a value above a threshold, and for processing the selected pair using a multi-channel processing operation to derive first multi-channel parameters for the selected pair and to derive first processed channels. The iteration processor is configured to perform the calculating, the selecting and the processing using at least one of the processed channels to derive second multi-channel parameters and second processed channels. The channel encoder is configured to encode channels resulting from an iteration processing to obtain encoded channels.Type: GrantFiled: October 18, 2022Date of Patent: April 9, 2024Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Sascha Dick, Florian Schuh, Nikolaus Rettelbach, Tobias Schwegler, Richard Fueg, Johannes Hilpert, Matthias Neusinger

Patent number: 10770084Abstract: A decoder for decoding a plurality of spectral-domain audio samples is provided. The decoder includes a first decoding module for generating a first group and a second group of time-domain intermediate audio samples from the spectral-domain audio samples. Moreover, the decoder includes an overlap-adder for overlap-adding the first group of time-domain intermediate audio samples with an overlap of more than 5% and at most 50% with the second group of time-domain intermediate audio samples. Furthermore, the decoder includes a second decoding module for generating a third group and a fourth group of time-domain intermediate audio samples from the spectral-domain audio samples. Moreover, the decoder includes an output interface.Type: GrantFiled: March 22, 2018Date of Patent: September 8, 2020Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Christian Helmrich, Bernd Edler, Tobias Schwegler, Florian Schuh
