Noise Gate – What is it and how does it work video tutorial details all the workings of a noise gate and how best to use it treat vocals.
Getting rid of background noise or that annoying headphone spill can be a nightmare to deal with.
Noise…noise is everywhere and can creep up on you unannounced even in the pristine clear digital realm. In fact, noise is exposed even further because of the purity of the digital realm.
Noise
The most common forms of noise are microphone related. Headphone spill which is the microphone picking up the headphone over-spill is the most common form of noise that plagues mic recordings. Background noise – anything from the room, outdoors or even the singer moving around and knocking the stand are termed as noise as they are printed on the recording. Now imagine countless channels of mic recordings all playing at the same time in your mix. The noise sums in exactly the same way that ‘clean’ audio does.
Noise Gate
To get rid of noise we use a process that has remained unchanged since inceptions. It is the Noise Gate.
A Gate is a device or plugin that behaves like a downward expander with infinite ratio. A downward compressor processes the signal that exceeds the threshold. A gate processes the signal that falls BELOW the threshold. When the signal falls below the threshold it is attenuated or silenced. The gate opens as the signal rises above a threshold, and closes when it falls below it. How this is achieved is determined by the various features gates offer.
Noise Gate – What is it and how does it work video covers all of the following:
Attack and Release determine how the gate closes and open.
Some gates offer a hold feature that keeps the gate open for a specified time and prevents ‘chattering’ (the gate opens and closes rapidly in succession).
Some gates will work in either Peak or RMS Mode.
Range determines by how much the signal is attenuated. This is often used to avoid abrupt closing/opening. It allows for a smoother transition.
Some gates have side-chaining which helps to fine-tune the gate’s behaviour.
In the video, I use a rap vocal take and run it through a gate processor. I explain each and every parameter of the gate processor plugin and guide you through the best settings to use for different scenarios. I show you how best to use a gate processor on a fast and dynamic vocal take making sure to show you the pitfalls to avoid when using dynamic processors like a noise gate. I explain how to use the gate’s side-chain filtering to process vocals.
