WING EXPANDER
An (upward) expander acts the opposite way of a compressor. It makes loud signals that pass over a threshold louder while keeping quiet signals the same. A compressor with a ratio of 1:3 will require 3dB of additional input signal to achieve a 1dB increase in the output signal. An expander with a 1:3 ratio will produce a 3dB louder output signal for every 1dB in increased input. Neither a compressor nor a gate will affect the signal if it stays below the threshold. For that, you need a gate.
Behringer's integrated WING Expander has similar parameters to the WING Compressor. Besides how the ratio works, the critical difference is that you should apply the makeup gain to attenuate the signal rather than amplify it. Since signals over the threshold will be louder than in the bypassed state, you should set the makeup gain to compensate for that increase in loudness.
You'll probably not need an expander in live audio, but it's there for you if you do. If you want to know more about expanders, please check out this article on izotope.com.
噪声门可以作为扩展器使用,这可能是我在大多数情况下会使用的,但我可以想象出一种情况,你想使用本部分的扩展器而不是门,最明显的是你想使用门部分的效果,而该效果在压缩器部分是不可用的,然后使用插入的压缩器或根本就没有压缩器。记住,效果的顺序可以随时重新安排。
