| description | The invention relates to a decoding method and a decoder of an audio signal, a medium and an encoding method. The decoding method and decoder for the audio signal are provided. In particular, the decoding method includes the steps: receiving a waveform-coded signal having a spectral content corresponding to a subset of the frequency range above a cross-over frequency. The waveform-coded signal is interleaved with a parametric high frequency reconstruction of the audio signal above the cross-over frequency. In this way an improved reconstruction of the high frequency bands of the audio signal is achieved.
本公开涉及音频信号的解码方法和解码器、介质以及编码方法。提供用于音频信号的解码和编码的方法和装置。特别地，用于解码的方法包括接收具有与高于交叉频率的频率范围的子集对应的频谱内容的波形编码信号。波形编码信号与高于交叉频率的音频信号的参数高频率重构交错。以这种方式，实现音频信号的高频率带的改善的重构。 |
