ADAU1772 for Noise Cancellation

   I'm currently using the ADAU1772 evaluation board and I'm able to create a basic noise cancellation headset using SigmaStudio.  I'm new to this part and DSPs in general and I'm wondering that an effective way is to tune the noise cancellation effect.  For instance, if I have external noise at 300Hz how do I tune to improve cancelling at that frequency?


   I'd like to use the eval board as a research tool for cancelling out specific frequencies and learning how cancellation changes as frequency increases.
