Pink Generator and EQ adjustment

Branched to a new discussion

I just got the new eval board (ADAU1442) and it was easy to get up and running.  I created my first design with two inputs, a 28 channel EQ, three way crossover and six outputs.  It runs fine.


I need to add an input for an spl mic (no problem) and connect to a pink generator.  I then need to use one of the switches on the extra jumper board to turn on the pink generator and sweep from 20-20K.  I will need a graphical display (line or bar) for the results of the pink sweep.  I also need to see the EQ so that I can adjust it and then sweep again or keep the pink on and keep adjusting the EQs until I am happy with the response.


Eventually, this will need to be done through a PC GUI, but I just want to get the basic circuit running first.


Suggestions would be greatly appreciated.
