I'm trying to design a system where we want to add in some sort of an echo cancellation block, which will need the output signal fed into the mic signal.
Should I go for single HW input with 3 channels in the layout? or two HW inputs with one for 2 mics and one for the speaker(output)?
Also, mics vs the speaker run in different sampling rate, so I'm hoping the latter case works.
If it doesn't (which the documentation seems to suggest), is there any way to handle the downsampling on the output signal inside the AWE core?
If it can't, my only option would be to perform downsampling outside the AWE core and then feed it to the AWE with DMA right?
