The Release is the time it takes for the gate to close after the audio signal goes below the threshold. Typically you’ll want to use a fairly quick attack time so that the gate will be open for the beginning of the note being played. The Attack is the time that it takes for the gate to open. Typically we would set the threshold just above the noise level this allows any intended signal to pass through but will cut off as soon as the signal goes below that. If the audio level goes above the threshold all the signal will pass through. In my example, noise floor hovers around -47dB, therefore I am setting my threshold at -44dB.Threshold sets the level that the gate opens. Your threshold in noise gate should be slightly higher than your noise floor to make sure that noise gate will remove all the background noise. Recording/playback levels bar (yours might be vertical). Usually it’s below -40dB, but depends on how loud your environment is and your recording settings. The maximum recording/playback level is your noise floor level. Make a quick recording of your environment and look at recording levels bar while recording or playing it back. To measure noise floor you’ll be required to record your environment in silence. You can determine your optimal noise gate threshold by measuring the noise floor. Optimal Attack, Hold and Release settings in Noise gate might be quite similar for everyone’s vocals, however, Threshold will vary a lot depending on the environment you’re in and will differ for everyone. My Noise Gate settings in Adobe Audition Before applying Noise Gate in Adobe Audition After applying Noise Gate in Adobe Audition Noise gate Threshold, Attack, Release and Hold scheme.īelow are the Noise Gate settings I generally use in Adobe Audition for voice overs and I slightly adjust them if I notice some choppiness or unwanted background noise residues. Setting hold too high might leave a lot of the background noise in your recording. Setting hold too low will cause noise gate to cut the end of your sentences. It’s similar to release, except the process is not gradual.
