CY4C29466语音跟踪音频滤波器建议

大家好，
我正在做一个电路，在木偶上移动一个嘴巴伺服装置，跟踪实时声音输入。我现在的计划是使用模拟块来将音频运行到PGA中，然后通过带通滤波器，最后进入ADC。我一直在使用过滤器向导来设置参数，但是当我查看模拟输出总线上的带通滤波器的输出时，ISEE看起来像是被截断的信号，可能是滤波器采样率。不管怎么说，好像在那个信号上运行ADC不会给我一个可靠的声音幅度。接下来我该做什么，我能为社区提供什么让你看？对于将过滤器向导中的参数设置为什么，有什么建议吗？

  Hello all,
    I'm working on a circuit to move a mouth servo on a puppet, tracking live voice input. My current plan is to use the analog blocks to run the audio into a PGA, then through a band pass filter, and finally into an ADC. I have been using the filter wizard to set my parameters, but when I look at the output of the Band pass filter on the analog output buss, I see what looks like the signal chopped up, probably at the filter sample filter rate. Anyway, it looks like running the ADC on that signal would not give me a reliable voice amplitude.  What should I do next, and what can I provide to the community for you to look at?  Any suggestions for what I should set the parameters in the filter wizard to?
