CY4C29466 voice tracking audio filter suggestions
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?
