Use Noise Gate to reduce or eliminate noise in quiet or silent parts of a recording. Brief noises, such as mouse clicks or microphone bumps can be muted as well. A noise gate cannot remove noise from louder parts of the recording. Use Noise Reduction for that instead. To completely delete silences from a recording, use Silence Reduction.
Use Maximize Volume before using this effect to ensure volume is optimal for the presets.
| Noise Gate Settings | ||
|---|---|---|
| Setting | Description | |
| Threshold (dB) | Sets the level of audio that is considered noise. Audio below the threshold is reduced. The threshold should be set as low as possible so that only noise is removed. If the threshold is set too high, short and quiet sections of audio may be muted too. | |
| Attack (s) | Sets the amount of time required to fade out to complete silence when the audio is below the threshold. | |
| Release (s) | Sets the amount of time required to fade in to full volume when the audio rises above the threshold again. | |
| Reduction (%) | Sets the level of reduction in the quiet parts. Normally this value would be set to 100 to replace the quiet parts with complete silence. A value of 25 reduces the noise only slightly (-3dB). | |
| Ignore (s) | Sets the duration of brief sounds to ignore, even if they are above the threshold. Any sound less than this duration is muted. Use this to remove clicks, pops, and other very short sounds. Set this to zero to ensure that all sounds above the threshold are retained. | |
