Hi,

I am trying to implement an ANC prototype (Feedforward, Feedback, Hybrid) on an ADAU1787.
Are there any ANC examples available?
During preparation I also found out that the FxLMS is not available in SigmaStudio 4.5 Toolbox for ADAU1787.
Is there a reason why this is not available or am I doing something wrong?

BR,
Mario

Hi Mario,

Unfortunately, we are unable to provide any reference designs for ANC on the ADAU1787, but all the tools to create a high-quality ANC implementation from scratch are available in the FastDSP.

The ADAU1787 SigmaDSP core is based on the Sigma200 core (found in the ADAU1442, for example). The FxLMS filter has only been implemented in the Sigma300 and Sigma350 cores (ADAU1452 and ADAU1462, for example). So, you're not doing anything wrong, it's just not there!

Best regards,

Tyler Krome
