Patent number: 8687829Abstract: A parameter transformer generates level parameters, indicating an energy relation between a first and a second audio channel of a multi-channel audio signal associated to a multi-channel loudspeaker configuration. The level parameter are generated based on object parameters for a plurality of audio objects associated to a down-mix channel, which is generated using object audio signals associated to the audio objects. The object parameters have an energy parameter indicating an energy of the object audio signal. To derive the coherence and the level parameters, a parameter generator is used, which combines the energy parameter and object rendering parameters, which depend on a desired rendering configuration.Type: GrantFiled: October 5, 2007Date of Patent: April 1, 2014Assignees: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V., Dolby Sweden AB, Koninklijke Philips Electronics N.V.Inventors: Johannes Hilpert, Karsten Linzmeier, Juergen Herre, Ralph Sperschneider, Andreas Hoelzer, Lars Villemoes, Jonas Engdegard, Heiko Purnhagen, Kristofer Kjoerling, Dirk Jeroen Breebaart, Werner Oomen

Patent number: 7961890Abstract: A parametric representation of a multi-channel audio signal describes the spatial properties of the audio signal well with compact side information when a coherence information, describing the coherence between a first and a second channel, is derived within a hierarchical encoding process only for channel pairs including a first channel having only information of a left side with respect to a listening position and including a second channel having only information from a right side with respect to a listening position. As within the hierarchical process the multiple audio channels of the audio signal are downmixed iteratively into monophonic channels, one can pick the relevant parameters from an encoding step involving only channel pairs carrying the information needed to describe the spatial properties of the multi-channel audio signal.Type: GrantFiled: December 21, 2005Date of Patent: June 14, 2011Assignees: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung, e.V., Coding Technologies AB, Koninklijke Philips Electronics N.V.Inventors: Andreas Hölzer, Jürgen Herre, Heiko Purnhagen, Kristofer Kjörling, Jonas Röden, Lars Villemoes, Jonas Engdegard, Jeroen Breebaart, Erik Schuijers, Werner Oomen

Publication number: 20070250308Abstract: A method and device for transcoding a first audio or video signal represented in one compression format to a second audio or video signal represented in another compression format. The transcoding is performed by direct mapping symbols from the first signal format to symbols of the second signal format. The transcoding can be performed between different formats or between the same format but with different bitrates. Such formats may be MP3 or aac.Type: ApplicationFiled: August 8, 2005Publication date: October 25, 2007Applicant: Koninklijke Philips Electronics, N.V.Inventors: Jun Lee, Werner Oomen, Fransiscus De Bont

Publication number: 20060147047Abstract: In the method of coding the audio signal, the values of first parameters (P1,1), which represent aspects of the audio signal at a first instant (ti), are calculated to obtain first calculated values (A1,i). The values of second parameters P2,i), which represent the aspects of the audio signal at a second, later, instant (t2), are calculated to obtain the second calculated values (A2,i). The number of the first parameters (P1,i) and the number of the second parameters (P2,i) differ. A subset (SUS2,i) of the second parameters (P2,i) is associated with a particular portion (SFRAi) of a frequency range (FR) of the audio signal This frequency range (FR) of the audio signal is preferably selected to cover all the frequencies present in the audio signal.Type: ApplicationFiled: October 31, 2003Publication date: July 6, 2006Applicant: Koninklijke Philips ElectronicsInventors: Erik Schuijers, Arnoldus Werner Oomen, Matheus Johannes Mans
