Sonar is recorded, strange sound, chirping in recordings
Probably some filter to enhance audio experience is applied to speaker or mic.
Try different frequency in Settings → Sleep tracking → Test sensor, choose a frequency from the drop down menu list.
When you find the least affected frequency, you could try increasing the recording threshold a bit in Settings → Sleep noise recording → Recording volume threshold.
|We have also discovered, that this exact issue can be solved by different positioning of the phone - if the bottom of the phone (where mic and speaker are) is not touching any surface, the artifacts are gone. So try to put the phone on a book or something similar with the bottom of the phone over the edge. If you are not hearing the sonar itself during tracking, but it only gets recorded, this usually helps.|
