I am currently working with the ADAU1701 as a DSP core for active loudspeakers and i have a digital input on this board but I am now looking at the switching hub that will feed the DSP in each monitor the left and right digital signal.
What i need to do is accept inputs from the following formats
Optical Spdif Input
Coax Spdif Input
USB Audio Input
HDMI Audio Input
Then route the selected input to a dedicated justified left and right output to feed to the ADAU 1701 in each monitor.
Is this the best way to do this? i currently have SPDIF conversion on the DSP board but its getting chip heavy and im thinking i am over complicating my initial design.
Can the ADAU144- do what im asking and help simplify everything?
