SR3 v1.2 ANR question ( Active noise reduction )

[Judge]

hi ,

I use SR3 V1.2 to test. I enable ANR, play the recording directly in the loop.

About every five seconds, a second or so of unusual sound appears. The rest of the time sound is normal.

When I disable ANR, there won't be this one-second sound. All sounds are normal.

I think it's a problem with this algorithm. How to solve this problem?

I've tried a lot of ANR parameter configurations, but there's always this problem.

I tried to port the ANR algorithm to other projects, test it separately, and still had this problem.

Can you test this question? Can this ANR algorithm work properly?

Hi Judge,

please refer the  nRFready Smart Remote 3 nRF52 Firmware Version 1.2.1 Release notes

• When the Active Noise Reduction (ANR) functionality is enabled, beeps are added to the signal at regular intervals. For full, unrestricted version of the ANR functionality, contact vocal.com®.
