Bunch of noises in the audio data

I was trying out some simple spelling to the quickfeather. The audio data collected in DCL contains a lot of noises, did anybody know how to filter/remove the noises or configure/fine-tune the onboard Infineon mic? The model failed miserably with this kind of data.

Hello
I also confirmed, but the situation is the same.
It's the same even if I attach a microphone to the outside, so I'm giving up using it now.

So you attach a 3rd party microphone?
I'm hoping somebody from QuickLogic to get us through this but still no reply from them, I wonder do they look at this forum or not. Anybody else having the same issue here?

Please let us know which QORS_SDK version you used for collecting audio data. The latest tag version 1.7.0 has improvement to eliminate the noises seen in some systems. Link

I was using v1.5.0 before. Same noise issue even I tried v1.7.0. Could it be some fine-tuning or pre-processing needed for the MIC?

This should be fixed in the latest DCL release (2020.10.6, or you may see an update for 2020.10.7 come Monday the 8th.)
