Download Noise Gate for Audacity in 2020 (Install & Update)

A noise gate Audacity is a kind of “audio gate” that is “Open” for sound to pass through when the level is above “Threshold.” If the audio is below the threshold level, the gate shuts and seizes, or the signal goes down, which makes it significantly quiet. A noise gate only reduces the noise level during quiet sessions between sounds, but it does not eliminate noise from a signal. It is useful in many situations.

Noise gate comes to play, lowering the noise level, in the silent parts of a recording where the noise is apparent. For instance, dither noise that is evident in a recording can be eliminated with Noise Gate in 16-bit audio files. In quality preference, enable a 32-bit default sample format and disable “High Quality” dither.

Sometimes, noise removal by other methods can cause a degradation of sound quality. Here, a Noise Gate can effectively reduce the noise level to an extent between sounds and not affect the actual sound recorded quality. When a piece of recorded music has low intermittent noise, of a particular type, in the background that is audible during pauses in a recording and Noise Gate can silence the noise. Use Noise Gate to silence or effectively reduce the noise levels in periods that should be silent.

Noise Gate Plug-ins for Audacity

Plug-ins or libraries add functionality to Audacity, giving you special effects and capabilities like audio generation and analysis. Additional libraries allow you to import and export more audio formats.  

Nyquist Noise Gate is a plug-in with several features and settings that make it practical and unobtrusive. The most important parameter when using Noise Gate is to set the threshold carefully. Nyquist Noise plug-in has an analysis tool that assists in setting the threshold level right. 

  1. Open Noise Gate Effect and select noise only
  2. Click on Function > Analyze Noise level and take note of the suggested threshold level.
  3. Choose a part of the audio track that has both sound and silence.
  4. Use Noise Gate with these settings: Click on Function > Gate Level reduction > -100- Carefully listen to see that the noise is being cut, yet the audio is still present. The gate is fully closed and produces an absolute silence when closed, and sound may be unnatural. However, you should easily hear if the threshold is set right. Press CTRL + Z to undo if it is necessary to adjust the threshold level.
  5. Once your threshold is correctly set, increase the “Level reduction” settings to the highest environment that produces a reasonable amount of gating. The default setting Level is – 12 dB, and it works well.
  6. If the setting is up to satisfaction, then apply Noise Gate to the whole song. 

The gate minimum is 10ms, and it may open fully then close almost instantly as the audio level crosses the threshold. At the maximum gate may “Flutter” or “Snap.” The gate maximum (1000ms) the gate slowly opens(fades in) one second before the sound level goes past the threshold then gradually shuts (Fades out) after the audio level drops below the threshold for a second. You can achieve longer gate times(up to 10 secs) by typing in the text box instead of a slider.
