we are currently redesigning our voice control unit and for that we need a IC that can transform a mic signal and use it with a digital audio signal to do AEC filtering. I've noticed the integrated DSP part in the ADAU1777 and came across some documentation on AEC filter design with sigma studio. Before ordering dev-boards, i wanted to make sure if understood these possibilities right. Am i able to configure the DSP of the ADAU this way or do you have a better solution for these circumstances. The modified output-signal should then be used via DAC and the mic signal should be forwarded digitally for further bluetooth usage.
Best regards and thanks in advance!
