16.10 使用噪声门进行音量控制

Noise gates control sound at the quiet end of the scale. When you record a track there might be sections of silence, perhaps between verses. However, you might notice on playback irritating sounds have been recorded at a low level during these periods. A noise gate can detect these and filter them out. Like the compressor, the gate can be quite simple or more sophisticated. Here we are going to focus on the basic noise gate controls:
噪声门控制段落中较安静部分的声音。当你们录制一条轨道时,可能会有一些无声的片段,也许是在段落之间。然而,你可能会在回放时注意到,在这些电平处于较低的地方,有恼人的声音已经被录制下来了。噪声门可以检测到这些信号并将其过滤掉。像压缩器一样,噪声门可以非常简单,也可以更复杂。在这里,我们将重点介绍基本的噪声门控制:
 Threshold - Used to specify a minimum sound level below which the noise gate will kick in.
“Threshold(阈值)”——用于指定噪声门将启动的最低电平。
 Attack - Specifies how quickly the gate kicks in. Too soon can cause the natural decay to be cut off.
“Attack(启动)”——指定门的启动速度。太短会导致自然减弱的部分被切断。
 Hold - Specifies how long the gate remains open after the signal falls below the Threshold.
“Hold(保持)”——指定信号降至阈值以下后,门限保持打开的时间
 Release - Determines how soon the gate closes after the signal has fallen below the threshold.
“Release(释放)”——这决定了信号降到阈值以下后,门限关闭的时间。
 Hysteresis - The degree of tolerance allowed before opening or closing the gate (rather like a thermostat!).
“Hysteresis(滞后)”——打开或关闭门限之前允许的容限程度(相当于自动调温器!)。
This example, uses the project All Through The Night COMP.RPP

Example
示例
1. Solo the Vox track.
1.独奏VOX轨道。
2. Play the song from just before the end of the first verse. If you listen carefully (especially thru headphones) you can hear some unwanted sounds during the otherwise silent passage. Certainly you can see this on the track’s VU meter.
2.从第一段结束前开始播放这首歌。如果你仔细听(尤其是通过耳机),你会在原本安静的段落中听到一些不想要的声音。当然,你可以在轨道的VU表上看到这一点。
3. Open the FX Window for this track and add Cockos VST ReaGate.
3.打开该轨道的FX窗口,添加Cockos VST ReaGate。
4. Play the song again. Adjust the Threshold fader (the first on the left) to a level just above that at which the Threshold’s VU meter is peaking during the quiet passages (see below). This will shut out the sound - visual confirmation is given by the VU meter on the right, which should now display no activity.
4.再放一遍这首歌。将阈值推子(左侧第一个)调整到略高于安静段落中阈值VU表峰值的电平(见下文)。这将关闭声音——视觉确认是由右边的VU仪表给出的,现在应该没有显示活跃。
5. You will probably find that the default settings for Attack, Hold and Release work quite well, but experiment with adjusting them if you wish. Save this file again.
5.你可能会发现,“启动”、“保持”和“释放”的默认设置非常有效,但如果你愿意的话,可以尝试调整它们。再次保存此文件。
You have just seen here a simple example of using a noise gate. Noise gates can be used to great effect and for a large number of applications (including with a drum kit to cut out the bleed between mics). Applications like that are more complicated and require a greater understanding of the noise gate's many parameters.
您刚才在这里看到了一个使用噪声门的简单示例。噪声门可以起到很好的效果,并可用于大量应用(包括使用套鼓时,以切断麦克风之间的串麦)。像这样的应用更加复杂,需要对噪声门的许多参数有更多的了解。
Channel
通道模式。
Modes. Like ReaComp, ReaGate supports different-channel modes (see previous page). These can be toggled on/off from the I/O button right-click menu. Multi-mono mode will cause the settings to be applied independently to each channel: multi-stereo mode applies these settings independently to each stereo pair.
与ReaComp一样,ReaGate支持不同的通道模式(参见上一页)。这些可以通过I/O按钮右键单击菜单进行切换。多单声道模式将使设置独立应用于每个声道:多立体声模式将这些设置独立应用于每个立体声对。
