Help with part selection for audio mixer

Hi,

I'm planing the design of a small remote controlled audio mixer that allows mixing of microfone inputs as well as sound from a connected BeagleBone board.

The mixer should have:

Inputs:

2 Microfones differencial or single ended

1 AUX Stereo Input differencial or single ended

2 Digital Input from BeagleBone (I2S)

Outputs:

     2x differencial or single ended line out

For Audioprocessing (tone control / fading, cross overs, noise reduction) I was looking at the ADAU1442

would this be a good choice? Or is there a better alternative? Would be nice if tone control devices(potis or rotary encoders) could be directly connected)

I'm a bit lost which ADC/DAC or Codec I should use as there are so many different parts.

It would be really great if someone could help me.

Best

Tom
