Noise Reduction in Audacity So how does Audacity’s “Noise Reduction” feature work? It starts by having you select a few seconds of “silence” on the audio track you want to clean up. This lets Audacity analyze the “noise” you want it to remove. This sample should be free from any vocals, keyboard tapping, or even breath sounds. It should only be the sound of the room. To add this to your podcasting workflow, be sure to leave 10-15 seconds of silence at the start on each audio file you record. That’ll make the Noise Reduction process much quicker and easier, going forward. Once you’ve highlighted your section of silence in Audacity, click Effect on the menu running along the top of the screen. Then, select Noise Reduction, then click Get Noise Profile. There are some settings in this box that you can tinker with. But the default settings are almost always good enough for cleaning up the types of background noise we’ve discussed. These custom settings come in the form of 3 sliders, which you can slide to the right to increase the severity of the process. If you use harsh or extreme settings, you can start to destroy the vocals themselves. A classic sign of Noise Reduction overuse is an “underwater” sound on the voice, which is often worse than the noise you’re attempting to remove in the first place. Stick with the default settings here if you can. Another great source of information on how to use audacity is The Podcast Host.
