摘要： 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.

摘要： In a multi-channel encoder generating several different parameter sets for reconstructing a multi-channel output signal using at least one transmission channel, the data stream is written such that the two parameter sets are decodable independently of each other. Thus, a multi-channel decoder is enabled to skip a parameter set which is marked as optional and/or has a higher version number when reading the data stream and still to perform a valid multi-channel reconstruction using a data set marked as mandatory or a data set having a sufficiently low version number. This achieves a flexible encoder/decoder concept suitable for future updates characterized by backward compatibility and reliability.

摘要： The present invention is based on the finding that parameters including: a first set of parameters of a representation of a first portion of an original signal and a second set of parameters of a representation of a second portion of the original signal can be efficiently encoded when the parameters are arranged in a first sequence of tuples and a second sequence of tuples. The first sequence of tuples includes tuples of parameters having two parameters from a single portion of the original signal and the second sequence of tuples includes tuples of parameters having one parameter from the first portion and one parameter from the second portion of the original signal. A bit estimator estimates the number of necessary bits to encode the first and the second sequence of tuples. Only the sequence of tuples, which results in the lower number of bits, is encoded.

摘要： The purpose of the invention is to bridge the gap between parametric multi-channel audio coding and matrixed-surround multi-channel coding by gradually improving the sound of an up-mix signal while raising the bit-rate consumed by the side-information starting from 0 up to the bit-rates of the parametric methods. More specifically, it provides a method of flexibly choosing an “operating point” somewhere between matrixed-surround (no side-information, limited audio quality) and fully parametric reconstruction (full side-information rate required, good quality). This operating point can be chosen dynamically (i.e. varying over time) and in response to the permissible side-information rate, as it is dictated by the individual application.

摘要： The present invention is based on the finding that an efficient code for encoding information values can be derived, when two or more information values are grouped in a tuple in a tuple order and when an encoding rule is used, that assigns the same code word to tuples having identical information values in different orders and that does derive an order information, indicating the tuple order, and when the code word is output in association with the order information.

摘要： A compact encoded representation of information values not exceeding a predefined size can be derived when a first encoding rule generating an encoded representation of the information values of variable length is compared to a second encoding rule generating an encoded representation of the information values of fixed length and when the encoding rule resulting in the encoded representation requiring the lower number of information units is chosen. Thus, the maximum bit rate can be guaranteed to be at least the maximum bit rate of the second encoding rule deriving the second encoded representation. Signaling the choice of the encoding rule by some rule information together with the encoded representation of the information values, the correct information values can later on be derived on a decoder side, using a decoding rule fitting the encoding rule used during the encoding.
摘要翻译： 当生成可变长度的信息值的编码表示的第一编码规则与产生固定长度的信息值的编码表示的第二编码规则进行比较时，可以导出不超过预定尺寸的信息值的紧凑编码表示， 当选择导致需要较少数量的信息单元的编码表示的编码规则时。 因此，可以保证最大比特率至少是导出第二编码表示的第二编码规则的最大比特率。 通过一些规则信息与信息值的编码表示信号对编码规则的选择，使用适合编码期间使用的编码规则的解码规则，可以稍后在解码器侧导出正确的信息值。
