Cleaning Up Audio With Noise Gate
A ‘noise gate’ (also called ‘gate’ or ‘audio gate’) is a dynamic processor that lowers the volume of a signal when the volume drops below the threshold. You can use a noise gate to remove quieter unwanted noise from your audio efficiently. Background noises, unwanted reverb tails, static, other instruments caught in the recording or the common ‘space-bar’ hit when you’ve finished recording can all be eliminated using a noise gate. ————— Using a gate can make the channel sound clear and defined. It can also help you isolate the audio on that channel that you want to work with. For example, you might have recorded snare audio that has bleed from the cymbals and toms. By setting up the gate to only allow the snare through you can process that channel only affecting the snare sound and not the other sounds from the drum kit. To set up a gate, instantiate a noise gate plugin on the channel you wish to clean up. Set the threshold to 0dB, the ratio to ∞:1 or the highest possible set...
