The noise could come from different sources:

  1. the microphone
  2. the connector
  3. the ADC
  4. the ADC reading
  5. in the FPGA if the algorithms are not correct
How do you detect your noise?

Depending on the compilation of quartus means that you have noise induces by the power supply, I think. 

Do you catch the data from the ADC synchronously without latches? Verify if your compilation warning specify some latches somewhere in your design.

Good luck.
