It is certainly possible to use the ADC/DAC on the STM32F407 board to add more inputs and outputs. We don't include any ADC inputs or DAC outputs in our BSPs because the 12-bit converters on the ST boards aren't useful for many audio applications, but you can add code to our reference BSPs to include any available input or output.
