I have a fairly quiet studio to record vocals. However, when I record, the noise of the required cooling fans get in the way! The selected area of the wave in the picture is the low-noise I want to get rid of, and it seems to have a detectable volume threshold!
I know that in Adobe Audition, I can impose the "Silent" effect, but it's tedious and seems way unprofessional! So, how may I efficiently "hush" the unavoidable noise after recording?
