7.2.4 Standard Compressor
标准压缩器
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 you choose, the more pronounced the compressor effect becomes.
4.
Attack.
Sets the time it takes for the compressor to begin attenuating a signal, once it passes the
threshold.
5.
Release.
Sets the time it takes for the compressor to stop attenuating a signal once it falls below the
threshold.
6.
Auto. Press to toggle Auto mode on or off.
When Auto mode is active, the Attack and Release
controls become inoperative, and a preprogrammed attack 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 gradu-
ally over time when the Threshold is reached by the input signal.
1.
开
/
关。在信号链中打开或关闭压缩器。
2.
门限。设定压缩器开始衰减信号的电平。
3.
比值。设定信号在阈值以上的量和它被衰减的量之间的关系。在
1
比
1
的比率下（通常写成
1:1
），不
发生压缩。在
4:1
的比例下，一个通过阈值
8dB
的信号被衰减到阈值的
2dB
以内（除以
4
）。你选择的
比率越高，压缩器的效果就越明显。
4. Attack
。设定信号通过门限后，压缩器开始衰减的时间。
5.
释放。设定当信号下降到噪声门限以下时，压缩器停止衰减的时间。
6. Auto
（自动）。按下以切换自动模式的开或关。当自动模式处于活动状态时，攻击和释放控 制不能
使用，而使用预先编程的攻击和释放曲线。在这种模式下，攻击被设定为
10ms
，释放被设定为
50ms
。
所有其他的压缩器参数仍然可以手动调整。
7.
微弱。按下以切换
Soft knee
的开或关。当设置为
"
开
"
时，当输入信号达到阈值时，压缩将随着时间
的推移而逐渐应用。
