Adobe Express: Reducing white noise with the DeNoise effect

Adobe ExpressTry it →Watch full video →Master Editor ·

Demo summary

The instructor demonstrates the DeNoise configuration window, adjusting the amount slider and toggling the effect to hear the reduction in hissing noise.

Step-by-step

  1. Open the DeNoise configuration window
  2. Adjust the amount slider to set the noise reduction percentage
  3. Select a noise-only part of the audio to test the effect
  4. Toggle the effect on and off to compare the difference
  5. Monitor the level meter to observe changes in the audio signal

Options

  • Set processing focus to specific frequency areas
  • Use the 'flat line' processing focus to apply denoise to the whole frequency area

Watch out for

  • Setting the amount too high makes the voice sound harsh, thin, and hollow
  • Using specific frequency processing focus requires advanced audio editing knowledge

Tips

  • Set the amount below 40% to maintain audio quality
  • Aim for a value around 30% to 40% for a satisfactory result
  • If noise is still present at 40%, focus on improving your physical recording environment instead of increasing the software effect

Highlights

“The higher you set the amount, the more noise will be reduced. However, that will make the voice harsh, thin, and hollow.”
