摘要： The present invention provides improvements to prior art audio codecs that generate a stereo-illusion through post-processing of a received mono signal. These improvements are accomplished by extraction of stereo-image describing parameters at the encoder side, which are transmitted and subsequently used for control of a stereo generator at the decoder side. Furthermore, the invention bridges the gap between simple pseudo-stereo methods, and current methods of true stereo-coding, by using a new form of parametric stereo coding. A stereo-balance parameter is introduced, which enables more advanced stereo modes, and in addition forms the basis of a new method of stereo-coding of spectral envelopes, of particular use in systems where guided HFR (High Frequency Reconstruction) is employed. As a special case, the application of this stereo-coding scheme in scalable HFR-based codecs is described.
摘要翻译：本发明提供对现有技术的音频编解码器的改进，其通过对接收到的单声道信号的后处理来产生立体幻象。这些改进通过提取在编码器侧描述参数的立体图像来实现，其被传输并随后用于在解码器侧对立体声发生器的控制。此外，本发明通过使用新形式的参数立体声编码来弥合简单伪立体声方法和真正的立体声编码的现有方法之间的差距。引入立体声平衡参数，其实现更高级的立体声模式，并且还构成了频谱包络的立体编码的新方法的基础，在采用引导HFR（高频重建）的系统中特别有用。作为特殊情况，描述了这种立体声编码方案在可扩展的基于HFR的编解码器中的应用。

A number of the subband signals are patched from consecutive channels of the filter bank to consecutive channels in the synthesis part of a digital filter bank. Each of the subband signals is patched from a channel with frequency index k to a channel with frequency index j not equal to k. The patched subband signals are adjusted in accordance to a desired spectral envelope. The adjusted subband signals are filtered through the synthesis part of a digital filter bank. An envelope adjusted and frequency translated or folded signal is obtained. An Independent claim is included for an apparatus for enhancement of source coding systems using high-frequency reconstruction techniques.
