摘要： Parameters being a measure for a characteristic of a channel or of a pair of channels, wherein the parameter is a measure for a characteristic of the channel or of the pair of channels with respect to another channel of a multi-channel signal can be quantized more efficiently using a quantization rule that is generated based on a relation of an energy measure of the channel or the pair of channels and an energy measure of the multi-channel signal. With generation of the quantization rule taking into account a psycho acoustic approach, the size of an encoded representation of the multi-channel signal can be decreased by coarser quantization without significantly disturbing the perceptual quality of the multi-channel signal when reconstructed from the encoded representation.

摘要： An apparatus and a method for generating a multi-channel synthesizer control signal, a multi-channel synthesizer, a method of generating an output signal from an input signal and a machine-readable storage medium are provided. On an encoder-side, a multi-channel input signal is analyzed for obtaining smoothing control information, which is to be used by a decoder-side multi-channel synthesis for smoothing quantized transmitted parameters or values derived from the quantized transmitted parameters for providing an improved subjective audio quality in particular for slowly moving point sources and rapidly moving point sources having tonal material such as fast moving sinusoids.

摘要： PARAMETERS (206) BEING A MEASURE FOR A CHARACTERISTIC OF A CHANNEL OR OF A PAIR OF CHANNELS, WHEREIN THE PARAMETER IS A MEASURE FOR A CHARACTERISTIC OF THE CHANNEL OR OF THE PAIR OF CHANNELS WITH RESPECT TO ANOTHER CHANNEL OF A MULTI-CHANNEL SIGNAL CAN BE QUANTIZED (200) MORE EFFICIENTLY USING A QUANTIZATION RULE (202) THAT IS GENERATED BASED ON A RELATION OF AN ENERGY MEASURE OF THE CHANNEL OR THE PAIR OF CHANNELS AND AN ENERGY MEASURE OF THE MULTI-CHANNEL SIGNAL. WITH GENERATION OF THE QUANTIZATION RULE (202) TAKING INTO ACCOUNT A PSYCHO ACOUSTIC APPROACH, THE SIZE OF AN ENCODED REPRESENTATION (204) OF THE MULTI-CHANNEL SIGNAL CAN BE DECREASED BY COARSER QUANTIZATION WITHOUT SIGNIFICANTLY DISTURBING THE PERCEPTUAL QUALITY OF THE MULTI-CHANNEL SIGNAL WHEN RECONSTRUCTED FROM THE ENCODED REPRESENTATION.

摘要： codificação hierárquica de àudio multicanais com informações colaterais compactas. uma representação paramétrica de um sinal de áudio multicanais descreve bem as propriedades espaciais do sinal de áudio com informações colaterais compactas quando as informações de coerência, que descrevem a coerência entre um primeiro e um segundo canais, são obtidas dentro de um processo de codificação hierárquica somente para pares de canais que incluem um primeiro canal tendo somente informações de um lado esquerdo em relação à uma posição de audição e incluindo um segundo canal tendo somente informações de um lado direito em relação à uma posição de audição. como dentro do processo hierárquico os canais de áudio múltiplo do sinal de áudio passam por downmix iterativamente para canais monofônicos, é possível escolher os parâmetros relevantes de uma etapa de codificação envolvendo somente os pares de canais que transportam as informações necessárias para descrever as propriedades espaciais do sinal de áudio multicanais.
