=== Gate Overview ===
Here's what a noise gate is designed to do - either let signal pass through or block it completely. It's helpful to think of it like a physical gate. When "open", the signal should pass through untouched as though the noise gate isn't even in your signal chain. When "closed", no signal should be allowed to pass through. The gate detects the signal's volume level, compares it to a threshold setting, and determines whether the gate should be open or closed.
Most gates also feature a Decay parameter. This specifies how quickly the gate should close - whether the signal should fade out over time or be abruptly silenced. a 0 setting means the signal should jump from the threshold level to no output. Higher settings fade out over the specified time period.
Some gates feature a Hold parameter. This keeps the gate fully open even after the signal level diminishes to less than the Close Threshold. After the hold time is elapsed, if the the signal level did not return above the Open Threshold, the gate starts to close at the speed specified in the Decay parameter.
As far as placement in the signal chain, I find the most effective place is first in the chain - most of the noise in your tone is coming from the low signal-to-noise ratio and hum produced by guitar pickups. Anything that is compressing the tone in your chain, such as compressors, distortion pedals, and amp models, are amplifying that initial noise. You might think that this would mean to put them last in your chain (or after a compressing element), but then they are very difficult to dial in. Note that the signal from your pickups is going to by the most dynamic, which makes it best for dialing in gate settings. If you only place a gate after some kind of compression, it will be difficult to find settings that let only let your playing through and not noise but still allow all your playing throughSee [[Effects Ordering/Position]].

=== Noise Gate vs. Hard Gate ===
The Noise Gate uses less DSP than the Hard Gate; however, so sometimes it's the Noise Gate or nothing, and I use it with lower settings then.
