Removing Noise with Audition
Noise removal
If you have hiss, noise, or a hum that shows up throughout a clip:
1. Open the clip in the waveform editor (double-click it).
2. Find a section between or before you talk that has the bad sound and select it.
3. Go to Effects > Noise Reduction/Restoration> Capture Noise Print.
4. Next, select the whole clip (double-click or drag).
5. Effect > Noise Reduction (process)...
Adjust the amount of noise reduction until the noise is gone but the audio still sounds good.
