First, you'll want to get the digital output expansion cards for your console:
Either the ADT1616 16-Channel ADATŪ Interface for DDX3216 or the TDF1616 16-Channel TDIF Interface for DDX3216.
Then, you'll need to get some sort of interface for your computer. The MOTU 2408Mk3 has both ADAT and TDIF and additional line level inputs giving you a lot of input channels. There are lots of other interface options here, too.
