ADAU 1761  control output volume by input

Hi,  I am hoping someone can point me in the right direction.  Firstly my application is in the audio band obviously,  but for a non audio application.  I have my demo board up and running.  I am using the 1761 to output a freq sweep, I want to use the Mic input(s) to adjust the output sweep to real-time control the amplitude (constant amplitude over freq).  I have played with and got working the Automatic level control via the DSP,  but can't see how to tie this to the output when using a DSP generated frequency sweep?

 

any idea would be appreciated
