You can make noiseless recordings using Krisp with Audacity. All you need is a 2-sided configuration.
Select Krisp Microphone from the audio panel. For that, make sure to have Device toolbars checked from View>>>Toolbars.
In the Krisp settings, pick the physical microphone you wish to use. Make sure that the Remove Noise toggle is turned on.
Start your noiseless recordings.
Note: The "Not used" indicator will be switched to "Used by Audacity" when there is an ongoing recording.
