Use the Gate Timeline FX to lower or remove the perceptible level of noise in an audio signal from an audio segment. It does
not, however, remove noise from the audio signal. The Gate Timeline FX is the second effect on the Audio Effects menu and
in the pipeline.
A noise gate is commonly used when the level of the desired signal generally stays above the level of the noise. In this case,
the threshold is set above the level of the noise. When the level of the signal remains above the threshold level, the gate
is open and both the signal and the noise are allowed to pass through. When the level of the signal falls below the threshold
level, the gate is closed and no signal is allowed to pass. In effect the perceptible noise is attenuated.
To apply Gate Timeline FX:
- Select the audio clip you want to apply the effect to.
- Either click the FX button or right-click on the clip and select Add Effect. The Effects menu appears.
- Click the Gate button. A gate icon appears on the clip.
- Adjust the settings for the effect. You can also click the Enter Editor button to access the full editor for the effect.
