9/7/2023 0 Comments Audacity noise reduction![]() By the time you realize you need noise reduction, it's too late. Some adventurous video editor claimed he got good results from a very bad but critical track by applying noise reduction more than once.Īnother unfortunate but way too common problem is people trying to apply noise reduction to garbage. If the "noise" has a personality very close to the person speaking, you may find only one value of each adjustment that works at all, and it's also possible that the least show damage and most natural effect happens with a little noise left in the background. The worse the damage, the more critical each value becomes. Too far (1000) and the noise will appear behind each spoken word, but not in between words giving you a pumping noise effect. Gently increase Smoothing up from zero until the gargling just goes away. While you're juggling that effect, you might get gargly/bubbling/echoes in the sound. You can go too far and the voices will start to sound mechanical, clipped, sterile, and "too perfect." The reduction number will do no reduction at all at 0 and the noise (say background hiss or buzz) goes down as you increase the value.
