Acoustic feedback Cancellation Software Sample Code

Dear Sir,


Now I'm evaluating the function of Acoustic feedback Cancellation for wireless mic-phone.

I refer to engineer zone's discussion and web article as below:


Acoustic Feedback Cancellation For Public Address Systems


ADAU1761 Adaptive filter


It seems some method did good work if I know which specific frequency/phase I would like to eliminate.

Unfortunately, as wrote in article, talker’s own movements could cause phase changes and it's hard to predict.

I would like ask whether ADI has related experience in this application and software sample code for reference?

It's best if you have sample code for blackfin due to I think ADSP-BF592 it's good choice potentially.


Thanks a lots!
