ADAU1467
Production
The ADAU1463/ADAU1467 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices...

Hello FJLDA,
The AEC block works on Sigma300/350 DSPs like ADAU145x/ADAU146x, those have more memory, support multi-rate processing and frequency domain processing. So, if you exactly want the AEC module then you have to go with the Sigma300/350 DSPs.
If you only want noise removal then the Noise removal>Noise reduction algorithm is available in Sigma200 DSPs like ADAU176x and ADAU144x, but that block runs in sample processing and will only run at 16KHz rate, since those DSPs don't support multi-rate processing you have to change your system sample rate to 16kHz, and you can't do much with those blocks since it's designed to work efficiently with only voice signals but not music signals.
The ADAU176x has only 1024 cycles per sample period at 48kHz.

Highlight the block as I did and press F1 to know more about that block.
So, if you want AEC and noise reduction + additional processing with decent amount of memory then you can choose ADAU145x series. It also has a lower grade version which runs at 147.456MHz (3072 cycles per sample period at 48KHz).
The ADAU146x series have more memory, GPIO etc.
Please compare the parts and choose which one is suitable.

Harish
