How can I measure audio-in signal SINAD or THD+N on ADAU1452miniz evaluation board?

Hi, I plan to use ADAU1452+AD1938 to do audio analyzer job (like measuring SINAD, THD+N,etc). From EZ, I know ADAU1452 has FFT libary in SigmaStudio. But it doesn't make it clear what the output of this FFT is, how we can make use of it. We bought a ADAU1452MINIZ evaluation board. But our project is stopped by this obstacle. Anyone can help? Thanks.
