Choose a sample of ONLY noise

After you have finished recording, highlight (click and drag) at least half a second of JUST background noise. IMPORTANT: make ABSOLUTELY sure you do not highlight any breaths or how to get rid of small acne scars bumps or any sounds other than the steady noise in how to get rid of small acne scars the room or mic.

Another potential cause of weird sounding after-effects of noise reduction is if you accidentally picked up how to get rid of small acne scars some of your own voice in the noise profile sample how to get rid of small acne scars at the beginning of this process. That is why I put so many warnings of why how to get rid of small acne scars it was so important to make sure you highlight ONLY how to get rid of small acne scars the steady background noise. No breaths, no vocal sounds, etc.
