Noise Gate Flashcards
What is a noise gate?
A hardware device or plugin which attenuates the signal below a given threshold.
When might a noise gate be effective?
A common application is with electric guitar to remove hum and hiss noise caused by distortion effects units.
Describe the threshold of a noise gate.
This sets the level at which the gate opens to let the sound through.
Describe the ratio of a noise gate. Give an example of its use.
The balance between the original sound and the gated sound. For example, instead of using the gate to totally mute the background ambience on a vocal track, you could allow some of the ambience to still be heard if so desired.
Describe the attack of a noise gate.
Sets the time it takes for the gate go from a closed state to an open state.
Describe the hold of a noise gate.
Allows the gate to be held in an open state after the signal level has fallen below the threshold.
Describe the release of a noise gate.
Use this to set how long it takes for the gate to go from fully open to fully closed. A fast release quickly cuts off the sound whereas slower release is more like a fade out. Beware not to set the release to fast as it can induce a clicking sound.
