Hello, I have updated recently Audacity to 3.6.4 version (from 3.5.1).
I edit some voiceovers and I use a spectral removal function a lot. I notice, that almost with every change I made to my tracks, a noise at high frequencies is added (cca above 16 kHz). However, this happens also when I merge my tracks together - the noise is also added at the places where I have digitaly zero sound (done by Ctrl+L).
First, I think this could be related to some global display properties of the spectrogram, but I checked my old projects and there is no issue. Concerning sound properties, everything is recorded with 44.1 kHz sampling rate, 16-bit, the same is the setting for the project.
Do you have any ideas what is behing that?
