正如大家的预期那样，每个AudioGroup都可以包含一堆不同的DSP音频效果。这些DSP效果是通过音频群组将效果，逐个以信号的形式叠加到上面。

As one would expect, each AudioGroup can contain a bunch of different DSP audio effects that are applied sequentially as the signal passes through the AudioGroup.

本课题基于小波理论设计软件算法，提出了模极值线群方法，抽取心电信号中若干具有临床价值的特征：QRS波群组态及其起点和终点、T波、S-T段。

In this paper, several characteristics of ECG from patients, such as QRS complex and its onset and offset T wave and S-T segment, has been detected using wavelet method.
