Patent number: 9552822Abstract: An apparatus for processing an audio signal is provided. The apparatus has a signal processor and a configurator. The configurator is adapted to configure the signal processor based on configuration information such that a configurable upsampling factor is equal to a first upsampling value when a first ratio of the second configurable number of samples to a first configurable number of samples has a first ratio value. Moreover, the configurator is adapted to configure the signal processor such that the configurable upsampling factor is equal to a different second upsampling value, when a different second ratio of the second configurable number of samples to the first configurable number of samples has a different second ratio value. The first or the second ratio value is not an integer value.Type: GrantFiled: April 3, 2013Date of Patent: January 24, 2017Assignees: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V., VoiceAge CorporationInventors: Markus Multrus, Bernhard Grill, Nikolaus Rettelbach, Guillaume Fuchs, Max Neuendorf, Bruno Bessette, Roch Lefebvre, Philippe Gournay, Stephan Wilde
