Adding more ADC inputs to STM32

Hi, I am working on a project where I need a lot of ADC inputs for analog controls (20-30) and was wondering if there was a good solution for this, either in terms of another component I can interface with the board or something in the STM32 family that has that number of inputs.

Currently using the STM32F4. ADCs would need to be able to read DC as well as AC input. 

Any suggestions are appreciated. Thanks!
