Level detector designer coefficient

Question asked by Mack on Apr 27, 2015

I would like to apply level detector designer module(Pass Thru type) on ADAU1761.

The module has 5 changeable parameters, Center Frequency, Bandwidth, Q, Time constant and Decay.

When I change one of them, 5 coefficients are written to ADAU1761. I have not found any relation between the parameters and the coefficients anywhere. To implement MCU-based design, I need what coefficients are sent to ADAU1761 from MCU.

Could I get a folmula to derive coeffients from 5 parameters?
