使用渲染音频信号的解相关的多声道音频解码器、多声道音频编码器、方法、计算机程序以及编码音频表示
摘要：
基于编码表示来提供至少两个输出音频信号的多声道音频解码器，被配置为依靠一个或多个渲染参数来渲染多个解码音频信号，以获得多个渲染音频信号，该多个解码音频信号是基于编码表示而获得的。该多声道音频解码器被配置为根据渲染音频信号导出一个或多个解相关音频信号，并将渲染音频信号或其缩放版本与该一个或多个解相关音频信号进行组合，以获得输出音频信号。多声道音频编码器提供用于控制音频解码器的解相关方法参数。
摘要（英）：

A multi-channel audio decoder for providing at least two output audio signals on the basis of an encoded representation is configured to render a plurality of decoded audio signals, which are obtained on the basis of the encoded representation, in dependence on one or more rendering parameters, to obtain a plurality of rendered audio signals. The multichannel audio decoder is configured to derive one or more decorrelated audio signals from the rendered audio signals, and to combine the rendered audio signals, or a scaled version thereof, with the one or more decorrelated audio signals, to obtain the output audio signals. A multi-channel audio encoder provides a decorrelation method parameter to control an audio decoder.
