Choose a Sample of ONLY NoiseĪfter you have finished recording, highlight (click and drag) at least half a second of JUST background noise (no voice or anything else you are actually TRYING to record) to select noise. It is crucial that you record a sample of the steady sound of the noise in your room and/or mic.

I recommend recording 3-5 seconds of silence at the beginning of your recording session so that you can record only noise.ĭuring this few seconds before you start speaking, make sure you don't take any audible breaths or make any other noises like lip-smacking or sniffing or bumping against the microphone, etc. So the very first thing you need to do is find a section of your recording where there is no voice, or breath, or anything EXCEPT noise. In order for Audacity to remove noise from your voice recording, it needs to know what 'noise' sounds like. OK, here is how to use noise reduction in Audacity. But the process works pretty much the same way in any program.įor some information on the most current and much better noise reduction tool in Audacity, check out our post - New Noise Reduction Tool In Audacity.
