摘要： A digital encoding process for transmitting and/or storing acoustical sigs and, in particular, music signals, in which scanned values of the acoustical signal are transformed by means of a transformation or a filter bank into a sequence of second scanned values, which reproduce the spectral composition of the acoustical signal, and the sequence of second scanned values is quantized in accordance with the requirements with varying precision and is partially or entirely encoded by an optimum encoder, and in which a corresponding decoding and inverse transformation takes place during the reproduction. An encoder is utilized in a manner in which the occurrence probability of the quantized spectral coefficient is correlated to the length of the code in such a way that the more frequently the spectral coefficient occurs, the shorter the code word. A code word and, if needed, a supplementary code is allocated to several elements of the sequence or to a value range in order to reduce the size of the table of the encoder. A portion of the code words of variable length are arranged in a raster, and the remaining code words are distributed in the gaps still left so that the beginning of a code word can be more easily found without completely decoding or in the event of faulty transmission.

摘要： A process for simultaneous transmission of signals from N signal sources via a corresponding number of transmission channels, in which the individual signals are divided into blocks and the blocks are transformed into spectral coefficients by transformation or filtering, the spectral coefficients undergoing a data reduction process. The blocks belonging to the individual signals are divided into sections. The respective current sections of all signals are processed simultaneously. The permissible interference for each section is determined utilizing a perception-specific model, and a request of currently required overall transmission capacity is calculated. The allotment of maximum transmission capacity at disposal for each individual signal is calculated from the overall transmission capacity at disposal and the currently required overall transmission capacity. Each signal is coded and transmitted with the thus determined capacity.

摘要： An integer transform, which provides integer output values, carries out the TDAC function of a MDCT in the time domain before the forward transform. In overlapping windows, this results in a Givens rotation which may be represented by lifting matrices, wherein time-discrete sampled values of an audio signal may at first be summed up on a pair-wise basis to build a vector so as to be sequentially provided with a lifting matrix. After each multiplication of a vector by a lifting matrix, a rounding step is carried out such that, on the output-side, only integers will result. By transforming the windowed integer sampled value with an integer transform, a spectral representation with integer spectral values may be obtained. The inverse mapping with an inverse rotation matrix and corresponding inverse lifting matrices results in an exact reconstruction.

摘要： For the reduction of the rounding error, a first and a second non-integer input value are provided and combined, for example by addition, in non-integer state to obtain a non-integer result value which is rounded and added to a third input value. Thus, the rounding error may be reduced at an interface between two rotations divided into lifting steps or between a first rotation divided into lifting steps and a first lifting step of a subsequent multi-dimensional lifting sequence.

摘要： An audio reproduction system is divided into a central wave-field synthesis module and a plurality of loudspeaker modules disposed in a distributed way, wherein synthesis signals for the individual loudspeakers as well as corresponding channel information associated to the synthesis signals are calculated in the central wave-field synthesis module. The synthesis signals for a loudspeaker as well as associated channel information will then be transmitted to respective loudspeaker modules via a transmission path, wherein every loudspeaker module obtains the synthesis signals and associated channel information intended for the loudspeaker associated to the loudspeaker module. A distributed audio rendering and digital/analog converting takes place in the loudspeaker module to generate the actually analog loudspeaker signals in a distributed way in spatial proximity to every loudspeaker. The division into a central wave-field synthesis module and the plurality of distributed loudspeaker modules allows that audio reproduction systems that are scalable with regard to the price can be generated in order to offer systems of different size scalable in price particularly for cinema reproduction rooms varying strongly in size.

摘要： In a method and a device for labeling a virtual product when distributing it to third parties, the virtual product being in a digital form, and the labeling indicating which rights a third party having received the virtual product has acquired in relation to same, the virtual product is initially provided by a distributor in the form of a file. Subsequently, electronic documentation for the virtual product provided is created, which has information regarding the distributor of the virtual product associated with it. Then the electronic documentation thus produced is associated with the file, which is then distributed to a third party. If the third party wishes to acquire rights to the file received, the necessary transactions are performed using the information associated with the electronic documentation so as to distribute a predetermined right to the third party from the distributor of the virtual product. After the transaction is completed, an electronic acknowledgement is created which has information associated with it which relates to the rights the third party has acquired by means of the transaction, and finally the electronic acknowledgement is associated with the file having the associated documentation which has been received by the third party.

摘要： A device for determining a component signal for a WFS system includes a provider for providing WFS parameters, a WFS parameter interpolator, and an audio signal processor. The provider provides WFS parameters for a component signal while using a source position and while using the loudspeaker position at a parameter sampling frequency smaller than the audio sampling frequency. The WFS parameter interpolator interpolates the WFS parameters so as to produce interpolated WFS parameters which are present at a parameter interpolation frequency that is higher than the parameter sampling frequency, the interpolated WFS parameters having interpolated fractions which have a higher level of accuracy than is specified by the audio sampling frequency. The audio signal processor is configured to apply the interpolated fractional values to the audio signal such that the component signal is obtained in a state of having been processed at the higher level of accuracy.

摘要： A device for acoustic display of a position of an object in a reproduction space, a plurality of loudspeakers being arranged in the reproduction space at spatially different positions such that different spatial positions may be represented acoustically by differently driving the loudspeakers, includes a signal associater and a loudspeaker driver. The signal associater is configured to associate an acoustic signal to the object. The loudspeaker driver is configured to establish one or several loudspeaker signals for the plurality of loudspeakers, wherein the one or several loudspeaker signals by which the position of the object is displayed are based on the acoustic signal associated to the object by the signal associater. The one or several loudspeaker signals may be established such that, when reproducing the one or several loudspeaker signals, the position of the object in the reproduction space is displayed acoustically.
