PROBLEMS WITH NOTCH FILTER AND PARAMETRIC FILTER

Hi Miguel, thanks for the reply,

what I'm trying is not a real project but some tests, I attach it.

I am trying to process easily, because I have few instructions available, "use ADAU1701 at 96kHz", a filter to partially eliminate the noise that air bubbles generate within a full face mask during breathing.

If you or your employees have advice, these are very welcome.

In ADAU1701 there is a FxLMS Filter or something similar

By carrying out these tests, the above mentioned problem occurred with SigmaStudio.

Best regards

Piero

Hi Piero:

We'll look into this problem. In the mean time can we recommend that you use the General EQ filters instead? Also, any chance you can share the offending schematic?

Thank you and regards

Miguel
