I'm looking for a cost effective codec that includes 4 ADCs and 2 DACs with a DSP capable of howl suppression and AEC. At the very least howl suppression. Is the ADAU1772 capable enough for this purpose?

The ADAU1772 can support these features, but for AEC the FDSP coefficients would need to be externally controlled via bank switch.
Is there an example project that you know of or have that demonstrates howl suppression?
