A cannot find a module for this in GDE. There is a thread on here that suggests that AEC can be implemented in the AIC3262 but I cannot find this module in GDE when I select the AIC3262 framework either.
What can you suggest in terms of possible solutions for microphone feedback suppression / AEC using GDE/MiniDSP - preferably using the AIC3254? There is a microcontroller as well which can assist - perhaps in creating the correct notch filter. The tricky part would be locating the feedback frequency.
I hope you have some suggestions for me. Spectral analyser module using multiple biquad bandpass filters perhaps?
