32 bit resolution for AIC3204

You need to set both codec and DSP in 32 bit mode.

Thank you Hyun. I'm really new in using ezdsp, does already exist a sample project which sets up the codec for 32 bits resolution?

We do not have a sample project running at 32-bit with the codec at the moment. 

You should be able to modify Spectrum Digital's AIC3204 test code to work at 32-bits. 

You may find the Test codes and BSL (board support library) here: C5505 eZDSP or C5515 eZDSP

I found that, on the ezdsp sample I've got, the background noise level is about -80 dB FS. With such a high noise background, 32-bit sampling won't outperform 16-bit sampling.
