Listen to the intro of the following video for a practical example of this effect. In this case, the gate will ignore the signal and act according to parameters set by the user. You could also use a gating plugin to achieve a вЂstutteringвЂ™ effect. There are cases when you might use a gate after вЂwettingвЂ™ effects like reverb to control the reverbs tail or if the recording has reverb embedded in it. i.e., Before you place effects like reverb or delay in your signal chain. YouвЂ™ll see the best results when using a noise gate on a вЂdryвЂ™ signal. Whether itвЂ™s sound spilling from the headphones of a vocalist, or your neighbors speaking loudly, a noise gate used correctly will drastically improve the quality of a recording. Ideally, you want to use a noise gate on any recording with unwanted noises in it. вЂHoldвЂ™ could work well for a recording that has a high dynamic range. While this function isnвЂ™t as crucial as the others, it is essential to note that setting the hold to a higher value will allow audio below the set thresholds loudness through. The hold function determines how long the gate will stay open before the release function takes effect. What to set the release to will depend entirely on the audio and what effect you want. A slower release time will allow the sound to fade out naturally, while a faster release time will shorten the tail of the sound. The release of a noise gating plugin controls how fast or slow the gate closes. Sounds with natural transients will typically use a faster setting, while smoother sounds will often use a more liberal one. The attack parameter will determine the speed at which the gate opens. YouвЂ™ll need to experiment a bit to find the sweet spot. Finding the correct level to use is entirely dependent on the loudness of the audio signal. The audio wonвЂ™t come through if it is set too high, and if it is set too low, no gating will occur. How much of the signal we will hear is determined by it. Any noise gate worth using will have four basic parameters you can tweak: threshold, attack, release, and вЂholdвЂ™ or sustain.ДЄrguably the most important control is the threshold. If the gate is closed, the recording is inaudible. How does a noise gate work?ДЄ noise gate works by setting its parameters to remove unwanted sections in a recording and allowing the desired parts to play. So how exactly do we go about working with a noise gate or a noise reduction program? What do all the controls on a noise gate plugin or hardware unit do? How will you be able to tell if a recording is вЂfixableвЂ™ or not? I will be answering these questions and more in the following article.

Note how this process reduces the noise, and the desired sound is essentially untouched. For the sake of this article, noise reduction will refer to the process of removing unwanted sound from a recording, specifically when the desired sound is present. One might also consider closing a window or turning a fan off as noise reduction. We do this by telling the program what it should consider noise and then telling the program to reduce that sound only. A noise reduction program or plugin is needed to reduce the noise to the point where it is inaudible relative to the loudness of the spoken words. As an example, a podcast with white noise or buzz throughout. Typically, this process would target the entire recording. Noise reduction is distinctly different from noise gating as you would most often use it on a sub-optimal recording with a constant or вЂstaticвЂ™ noise present. In the above diagram, the Output Level is what you will hear. Noise gating is a powerful tool that, when used correctly, will improve the quality of your audio immensely.

This technique, however, is not recommended as you might end up gating out audio that you want. You could also use a noise gate while recording to prevent these unwanted noises from even being recorded. We would set the threshold of our gating plugin or hardware unit to allow the snare through, and when it isnвЂ™t playing, the track is silent. Let us assume the snare drum is the loudest part of the recording. To put it plainly: A noise gate will block all unwanted sounds from being heard.ДЇor example, a snare drum mic recording some of the cymbals, toms, and kick drum. More specifically, targeting only areas when the desired sound in your recording is not playing. What could cause unwanted noise in a recording?ДЄ noise gate aims to remove unwanted noise/s in a recording, leaving purposefully recorded audio completely intact.What program/s should I use for noise reduction?.
