摘要：
An apparatus for decoding to obtain a reconstructed audio signal envelope includes a signal envelope reconstructor for generating the reconstructed audio signal envelope depending on one or more splitting points and an output interface for outputting the reconstructed audio signal envelope. The signal envelope reconstructor is configured to generate the reconstructed audio signal envelope such that the one or more splitting points divide the reconstructed audio signal envelope into two or more audio signal envelope portions, and to generate the reconstructed audio signal envelope such that, for each of the two or more signal envelope portions, an absolute value of its signal envelope portion value is greater than half of an absolute value of the signal envelope portion value of each of the other signal envelope portions.

用于解码以获得重构音频信号包络的装置包括用于根据一个或多个分割点产生重构音频信号包络的信号包络重建器和用于输出重构音频信号包络的输出接口。 信号包络重构器被配置为产生重建的音频信号包络，使得一个或多个分割点将重建的音频信号包络分成两个或更多个音频信号包络部分，并且生成重建的音频信号包络，使得对于每个 两个或多个信号包络部分，其信号包络部分值的绝对值大于每个其它信号包络部分的信号包络部分值的绝对值的一半。
