![]() Release time refers to how fast the gate closes (stops sound from passing through). This can result in an abrupt transient pop at the beginning of words. Generally speaking, with dialogue, it can often sound unnatural to have a fast attack, as the human ear is not used to such a swift transition from quiet to loud. AttackĪttack refers to the speed in which the gate opens (begins to let sound through). ![]() This can be tweaked to set a more subtle attenuation, removing any sudden silences which may seem unnatural. This dictates the amount of dynamic attenuation that takes place. In most cases, the subtle sounds that are unwanted in a recording space, particularly when recording dialogue, are consistently quiet, meaning that the gate will not have to work much to remove it.įor example, a computer fan may be audible, but this can be easily tamed as the volume of the fan will largely be the same throughout. A signal that is louder than this threshold will be heard, and the gate will cut out anything below the threshold. Threshold refers to the sensitivity of the gate. Common Noise Gate SettingsĪs one noise gate plug-in may look entirely different from that of another company, fear not! The controls are completely universal, whilst being intuitive for the user. Therefore, a noise gate can give the impression of a perfectly clean signal path, allowing your content and material to be the sole focus for the listener. This could be due to either a microphone, cable, or pre-amp. A noise gate can also be useful in removing a level of white noise, introduced in the recording path. Careful control of the parameters can result in a controlled and intimate signal path, ideal for dialogue. This can be in either the acoustic environment itself, such as a hum of an electronic device or a laptop fan.Īs recording locations may vary, a gate could even be put into use to control any unwanted subtle reverberate from the recording room. Why You Might use a GateĪ noise gate can be crucial in the removal of unwanted, low-level noise in a recording. As with manual audio editing, pops and clicks can devalue a recording of any kind, so it is worth knowing where attack and release come into play. Noise gates are used best when they go unnoticed. The gate is only triggered (closed) when there is no signal above the set threshold.Ĭompressors, on the other hand, rely on a ratio, which dictates how much dynamic control the compressor performs once the threshold is passed. A gate will allow the intended signal through (open), without baring any effect on the result. They’re either open or closed, as with physical gates! This is crucial to understanding the difference between a gate and a compressor. This can be perfect for getting rid of any computer fan noise, or other unwanted noises. A gate responds to an incoming signal, allowing anything above the desired dynamic threshold to be heard. How to Tweak the Settings for the Perfect Result and Identifying when the Setting are IncorrectĪ noise gate may not be the most exciting of audio tools, but what they bring to the table can be paramount in a number of scenarios, including recording, mixing, and post-production.How to Tell when a Noise Gate Could Help.
