看到有 Python版 http://www.oschina.net/code/snippet_120579_14455 和 java 版的 http://www.oschina.net/code/snippet_96412_9253 但是没有c#版的 就自己写了个 欢迎指教(See the the Python version http://www.oschina.net/code/snippet_120579_14455 java version http://www.oschina.net/code/snippet_96412_9253 but no c# version on their own to write a welcome advice)

用JAVA写的带通滤波代码，实现思路很简单，没有采用各种数字滤波的方法。而是通过傅里叶变换到频域，将要求外的频率均置0，再逆傅里叶变换得到的。效果还不错。(Written using JAVA bandpass filtering code to achieve the idea is very simple, without using a variety of digital filtering approach. But through the Fourier transform to the frequency domain, the frequency requirements are set to 0, then the inverse Fourier transform. Results were pretty good.)
