Lets do a test. Start a recording and leave the room for about 20 or 30 minutes. Come back and stop it. File > Export a WAV (Microsoft) 16-bit > OK.
While it’s open, cut out any large blue waves like any noise you may have made when you moved your chair.That should give you a field of super tiny clicks. Now select the whole track (button on the left) and Effect > Amplify > OK. That will tell you the repetition of the noise.
While that’s on the timeline take a picture of it and post it here. Then File > Export a WAV (Microsoft) 16-bit. We’ll want to keep that around a while for analysis.
How are you editing out the existing clicks?
