AA: Noise reduction/cleaning up audio

There is a small amount of clean-up that you can do to your audio. Do not expect that you can magically take out any background sounds! Especially if they are variable, like talking or dogs barking. However, sounds that are steady, like the hum of an air conditioner, can be reduced slightly using the method below:

1. Double-click your track to open it Waveform mode

2. View Spectral Display by clicking reddish box beside “Multitrack” in top left corner

3. In the Spectral Display of the waveform (colorful lower section), select a section that contains only room tone and is at least half a second long

4. Right-click on the selection and choose Capture Noise Print

5. Deselect (so the effect will apply to the whole recording) by clicking anywhere in the clip.

6. Choose Effects → Noise Reduction/Restoration → Noise Reduction

7. Settings:

• Noise Reduction ~70%

• Reduce by ~7 dB

7. Click Apply
