Set properly, when a gate closes it is muting unwanted audio or noise. That's why it's called a noise gate. This has nothing to do with the sidechain. How it is triggered, whether it be a separate audio source, or more commonly the source signal bandwidth limited, it is still gating off unwanted sounds, which in my book is considered noise.kozikowski wrote:The nit-picker is raising his hand.
This isn't a side chain noise gate. This is a side chain gate.
A gating effect is cause to happen from work on a second sound channel. It does not trigger a gate that then starts evaluating and processing noise.
i.e.: When I gate a rack tom on a drum kit, I'll bandwidth limit the trigger with a narrow response, depending on the tuning of the tom, somewhere around 315hz . This way cymbals, kick drum, and to an extent, the snare, all of which are unwanted signals in a tom mic, will not open said gate, and since the area of 315Hz is usually a pretty dominant tom frequency the gate will open without having to squash the threshold which in turn would shave off the peak response of the drum. NOTE: The gate must be inserted pre-eq/pre-fader so that eq and level changes (not gain) do not affect the performance of the gate.
