Standard Compressor 标准压缩机
1. On/Off. Turns the Compressor on or off in the signal chain.
2. Threshold. Sets the level above which the compressor
begins to attenuate the signal.
3. Ratio.Sets the relationship between the amount a signal goes above the
threshold, and the amount it is attenuated. At a 1-to-1 ratio (often written as
1:1), no compression occurs. At a 4:1 ratio, a signal that passes the threshold by
8 dB is attenuated to within 2 dB of the threshold (dividing by four).The higher
the ratio youchoose,the more pronouncedthe compressoreffectbecomes.
4. Attack.Sets thetimeittakesforthecompressorto begin
attenuating a signal, once it passes the threshold.
5. Release.Setsthetimeittakesforthecompressortostop
attenuating a signal once it falls below the threshold.
6. Auto.Pressto toggleAuto mode on or off.When Auto mode is active, the
AttackandReleasecontrolsbecomeinoperative,andapreprogrammedattack
and release curve is used. In this mode, the attack is set to 10 ms, and the release
is set to 150 ms. All other compressor parameters can still be adjusted manually.
7. Soft. Press to toggle Soft knee on or off. When set
to "on," compression will be applied more gradually
over time when the Threshold is reached by the input
signal.

1.开/关。开启或关闭信号链中的压缩机。
2.起点。设置高于压缩机开始衰减信号的电平。
3.比例。设置信号超过阈值的量与信号衰减的量之间的关系。在1比1的比例下
(通常写成1:1)，不会发生压缩。在4:1的比例下，通过阈值8 dB的信号衰减到阈
值2 dB以内(除以4)。选择的比例越高，压缩机的效果就越明显。
4.袭击。设置压缩机开始衰减信号所需的时间，一旦信号超过阈值。
5.版本。设置信号一旦低于阈值，压缩机停止衰减所需的时间。
