5. To remove the noise during silent breaks, first analyze the amplitude of the
noise. In TUTOR1, select a region with only noise (no voice), and run the
Statistics function under the Tools menu.Take note of the Maximum sample value
percentage. If you followed the preceding steps, it should be close to -60 dB.
6. Next, select Noise Gate from the Effects menu. The Noise Gate dialog will
appear.
7. In the Noise Gate dialog, slide the threshold level to a bit over the Maximum
sample value (in percentage). A value of -50 dB should be high enough to
differentiate the noise from the vocals. Press OK. Notice that the noise
during the silent regions should have disappeared (total attenuation). If it
didn’t, try raising the Threshold level until it does.
8. The other two parameters in the Noise Gate determine how fast the gate will
open and close. This will affect how the beginning and end of the sound
will fade in and out. If the Attack time is too slow, the beginning of the vocals
might get cut off. Likewise, if the Release time is too fast, the end of the vocals
will be cut. Experiment with these times until you can remove as much
noise as possible without removing any of the voice.
