I just discovered about atmega32u4 better ADC features ...
http://openenergymonitor.org/emon/node/2542
The main improvements to the ADC are:
1. differential input capability
2. programmable gain
3. 2.56V internal reference
4. high speed mode
5. more inputs
Any thoughts or comments on this to be used as audio input ?
