20090125313AUDIO CODING USING UPMIX - A method for decoding a multi-audio-object signal having audio signals of first and second types encoded therein, the multi-audio-object signal having a downmix signal and side information having level information of the audio signals of the first and second types in a first predetermined time/frequency resolution, the method including computing a prediction coefficient matrix C based on the level information; and up-mixing the downmix signal based on the prediction coefficients to obtain a first and/or a second up-mix audio signal approximating the audio signals of the first and second types, respectively, wherein up-mixing yields the first and/or second up-mix signals S05-14-2009
20090125314AUDIO CODING USING DOWNMIX - An audio decoder for decoding a multi-audio-object signal having an audio signal of a first type and an audio signal of a second type encoded therein is described, the multi-audio-object signal having a downmix signal and side information, the side information having level information of the audio signals of the first and second types in a first predetermined time/frequency resolution, and a residual signal specifying residual level values in a second predetermined time/frequency resolution, the audio decoder having a processor for computing prediction coefficients based on the level information; and an up-mixer for up-mixing the downmix signal based on the prediction coefficients and the residual signal to obtain a first up-mix audio signal approximating the audio signal of the first type and/or a second up-mix audio signal approximating the audio signal of the second type.05-14-2009
20100094631APPARATUS AND METHOD FOR SYNTHESIZING AN OUTPUT SIGNAL - An apparatus for synthesizing a rendered output signal having a first audio channel and a second audio channel includes a decorrelator stage for generating a decorrelator signal based on a downmix signal, and a combiner for performing a weighted combination of the downmix signal and a decorrelated signal based on parametric audio object information, downmix information and target rendering information. The combiner solves the problem of optimally combining matrixing with decorrelation for a high quality stereo scene reproduction of a number of individual audio objects using a multichannel downmix.04-15-2010
20110013790Apparatus and Method for Multi-Channel Parameter Transformation - 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.01-20-2011
20110282471Apparatus and Method for Synchronizing Additional Data and Base Data - For adding additional data, such as multi-channel extension data, to base data, such as conventional stereo data, a test fingerprint of test data relating to a test time instant of the test data is provided. The test data equals the additional data or the base data or depends on the additional data or the base data in parametric manner. Using the test fingerprint, reference time instant information is determined, which depends on a reference time instant in reference data, the reference data being the conventional stereo data. Finally, the additional data or the base data is manipulated, namely using the reference time instant information and the test time instant information, to obtain manipulated data, by which synchronous reproduction of the data information can be performed. Thus, a robust and flexible possibility for synchronous, especially late extension of base data by additional data is obtained.11-17-2011

20090174418Method and Device for Electrically Determining the Thickness of Semiconductor Membranes by Means of an Energy Input - A method and device for determining the thicknesses of semiconductor membranes uses electrical measurements. Energy is coupled into the membrane in a defined manner and the membrane thickness is determined from the distribution or diffusion of the energy. A change of state of the membrane is detected by measuring electroconductivity of measuring resistances at least one of which is on the membrane. The electroconductivity varies according to the temperature and the mechanical strain of the membrane, which both depend on the thickness of the membrane.07-09-2009
