7.36 Dynamic Splitting - Remove Silent Passages
7.36 动态分割-移除静默部分

REAPER's Dynamic Splitting is a powerful feature with many applications. Many of these are designed for use with tempo based composition, but it has other applications, such as to clean up a track and remove those passages that should be silent. This can be handy, for example, with a vocal track, to clean up the passages between verses which might contain unwanted background noises such as breathing or shuffling sounds.
REAPER的动态分割,是一个强大的功能,有许多应用程序。它们中的许多,都是为基于速度的作曲而设计的,但它也有其他的应用,比如清理轨道,以及移除那些应该是无声的部分。例如,对于人声轨道,这可以很方便地清理乐句之间的部分,这些乐句可能包含不想要的背景噪音,如呼吸或杂音。
Take, for example a vocal track. With dynamic splitting you can effectively tell REAPER to go thru the track and take out all of the passages where the vocalist isn't singing. These are the passages where you want the track to be silent and which otherwise might contain various breathing or other unwanted sounds.
以声乐轨道为例。通过动态拆分,你可以有效地告诉REAPER浏览轨道,去掉所有歌手没有唱歌的段落。在这些段落中,你希望轨道保持静音,否则可能会包含各种呼吸或其他不需要的声音。
To do this, first select the media item then right click over it and choose Item processing, Dynamic split items… . You then need to select the required parameters before splitting.
要执行此操作,请首先选择媒体对象,然后在其上单击鼠标右键,然后依次选择“对象处理”、“动态分割对象...”。然后,您需要在分割之前,选择所需的参数。
You are given immediate visual feedback before executing the command. Each split point is indicated by a colored vertical line and those areas marked for removal are shown as darker.
在执行该命令之前,系统会立即向您提供视觉反馈。每个分割点由一条彩色垂直线指示,标记为要删除的区域显示为较暗。
Dynamic splitting will be examined in more detail in Chapter 9, in the context of tempo based music production, but it can also be used as explained in the table below.
动态分割在第9章“基于速度的音乐制作”的相关中进行更详细的研究,但也可以按照下表中的说明来使用。
Start with settings similar to those shown here and adjust then as necessary.
从与此处显示的设置类似的设置开始,然后根据需要进行调整。
When used in this way, dynamic splitting basically employs a noise gate to tell REAPER how often and where to split your media items and which areas are to be removed.
当以这种方式使用时,动态分割基本上使用一个噪声门来告诉REAPER,分割媒体对象的频率和位置,以及要删除哪些区域。
Dynamic Split Option Setting to Remove Silent Passages
动态分割选项设置移除静默部分
At transients
在瞬态
Deselect this option when using dynamic splitting for this purpose.
将动态分割用于此目的时,请取消选择此选项。
When gate opens When gate closes
门限打开时,门限关闭时
You would be unlikely to select one of these options without the other. Both of these options need to be turned on, so that REAPER can work out the beginning and end of each passage that is to be removed.
如果没有其他选项,您不太可能选择其中一个选项。这两个选项都需要打开,以便REAPER可以计算出要删除的每个部分的开头和结尾。
Reduce split
减少分割
When using dynamic splitting for this purpose this should usually be deselected.
为此目的使用动态分割时,通常应取消选择此选项。
Min slice length
最小切片长度
This sets the shortest length for any slice. You will probably need to experiment to get it right. Usually, this should be set to a low value. Happily, REAPER's dynamic splitting interface gives you immediate visual feedback. You can see by looking at the screen when your settings are right. The illustration below shows the effect of setting this value too high. Notice that it can result in some recorded passages also being removed.
这将为任何切片设置最短长度。您可能需要尝试才能使其正确。通常,应将其设置为较低的值。令人高兴的是,REAPER的动态分割界面,可以为您提供即时的视觉反馈。当您的设置正确时,您可以通过查看屏幕来查看。下图显示了将此值设置得过高的效果。请注意,这可能会导致,某些录音的部分也被删除。
Min silence length
最小静音长度
This is another parameter that will require fine tuning. Set too high it will fail to catch all the periods of silence.
这是另一个需要微调的参数。设置得太高,将无法捕获到所有的静默时段。
Threshold
阈值
This setting is important, but usually has a reasonable range of acceptable values. If made too low, unwanted sounds might pass thru the noise gate. If set too high, you risk deleting quieter passages of the recorded material. Start around -50dB and make any necessary adjustments from there.
此设置很重要,但通常具有合理的可接受值范围。如果调得太低,不需要的声音可能会通过噪音门。如果设置得太高,可能会删除录音素材中较安静的部分。从“-50分贝”左右开始,然后进行任何必要的调整。
Hysteresis
滞后
This setting can be used to adjust the level at which the gate closes relative to that at which it opens. Raising the hysteresis figure closer to or even above 0dB will have create more splits.
此设置可用于调整门限关闭时相对于门限打开时的电平。把“滞后”的值提高到接近甚至高于0dB将会产生更多的分割。
Display gate threshold in media items
在媒体对象上显示门限
If enabled, this causes faint lines to be superimposed on the selected media items to show the threshold level.
如果启用,这会导致在所选媒体对象上叠加模糊的线条,以显示阈值的电平。
Remove silent areas
移除静默区域
This option should be enabled. Note that when ripple editing is enabled it will be applied as silent passages are removed.
应启用此选项。请注意,当启用波纹编辑时,它将在移除静默部分时应用。
Fade pads
淡变过渡区
Enabling fade pads can ensure a smoother transition from/to silence..
启用淡变过渡区,可以确保从静默区到静默区的过渡更平滑。
Other settings
其他设置
Leave them as shown above.
如上图所示。
Presets
预置
Enables you to save and later recall any combinations of settings as presets.
使您能够将设置的任何组合保存为预置并在以后调用。
Action to perform
要执行的操作
Split selected items will split only the selected item(s).
“分割选中的对象”,将仅分割选中的对象。
Split selected and grouped items. This will use the selected item(s) to determine where along the timeline splitting should occur. It will then apply the splitting to these items and to all other members of the group as well.
“分割选中和编组的对象”。这将使用选中的对象,来确定在时间轴上,分割应该发生在哪里。然后,它会将分割,应用于这些对象,以及编组中的全部其他成员。
Replace stretch markers in selected items or Replace stretch markers in selected items and add to grouped items.
“替换选中对象中的拉伸标记”或“替换选中对象中的拉伸标记并添加到编组对象中”。
A group of items is defined by selecting them and pressing G, or by choosing Group, Group items from the media item right-click menu.
通过选择对象编组,并按G键,或从媒体对象右键单击菜单中选择“编组”、“编组对象”,即可定义对象编组。
Other options are:
其他选项包括:
Add stretch markers to selected items, or to selected items and grouped items: stretch markers are explained in Chapter10.
“添加拉伸标记到选中的对象”,或“添加拉伸标记到选中的对象和编组的对象”:第10章介绍拉伸标记。
Add transient guide markers to items: this option causes transients guide lines (vertical broken lines) to be added to the selected item(s), without the items being split.
“添加瞬态参考线标记到选中的对象”: 此选项会导致将瞬态参考线(垂直虚线)添加到所选对象,而不分割对象。
