Unfortunately, the outcome could be overly distorted if the noise is extremely changeable or strong.

If you are still having issues, here are the following Audacity noise reduction best settings tips that might help you:

  • 1. Select the Residue button from the Noise: Hit Preview, listening for unnecessary traces of the desired signal. You can reduce the desired sound in the residue by decreasing Noise Reduction or Sensitivity.
  • Decreasing Noise Reduction may also reduce the possibility of losing the sound you keep, but it will increase the amount of the remaining noise in the result when you apply the effect.
  • Decreasing Sensitivity reduces the probability of losing the sound you wish to keep, but it increases the possibility of artifacts sounding when you apply the effect.
  • 2. Once you find the Noise Reduction and Sensitivity settings, which appear to do the least harm to the desired sound, hit the Reduce radio button and OK to apply the effect.
  • 3. Normalize or Amplify might be done before/after Noise Reduction. The audio volume normalizer can adjust the sound effects to enhance it and reduce the background noise efficiently.
