7.38 Spectral Peak Display
7.38 光谱峰值显示

Audio media items in arrange view are normally displayed as waveforms only. You can change this to a spectral display in which the media item is colored according to its audio frequencies, and in particular the most dominant frequency as it changes thru time.
排列视图中的音频媒体对象通常仅显示为波形。您可以将其更改为光谱显示,在光谱显示中,媒体对象根据其音频频率进行着色,尤其是随着时间的推移而变化的最主要频率。
Note that it is a diagnostic tool, designed to help identify and resolve issues in your mix. It is not a silver bullet, nor does is it offer an instant fix for all your problems. Nor is it intended that your eyes should replace your ears!
请注意,这是一个诊断工具,旨在帮助识别和解决混音中的问题。它不是灵丹妙药,也不能为你的所有问题提供立竿见影的解决方案。也不是说你的眼睛应该代替你的耳朵!
By viewing your waveforms as a range of colors, you might more readily be able to identify critical frequencies, especially where your ears are already telling you that you have a problem, or at least a decision to make.
通过查看一系列颜色的波形,您应该能够更容易地识别关键频率,特别是当您的耳朵已经告诉您有问题,或者至少需要做出决定的时候。
A simple example is shown below. Tracks 6 and 7 are a single acoustic guitar which has been set up with two mics. You can visually identify the frequency differences between the two tracks.
下面显示了一个简单的示例。轨道6和7是使用两支麦克风录制的同一把声学吉他。您可以直观地识别两条轨道之间的频率差异。
Spectral peaks can be helpful in recognizing content. For example, the lower and upper registers of a clarinet will show as different colors. A flute will be different again. Some other possible uses are:
光谱峰值有助于识别内容。例如,单簧管的低音和高音将显示为不同的颜色。长笛又会不一样了。其他一些可能的用途包括:
● To identify and pinpoint precisely unwanted noise (such as low end hum), or frequency spikes that you can hear in a track, or a particular event in a track, such as a percussion hit.
● 准确识别和定位不需要的噪音(如低频嗡嗡声),或您可以在轨道中听到的频率峰值,或轨道中的特定事件(如打击乐敲击)。
● To identify the precise location of a note (e.g. when a distorted guitar has been recorded).
● 识别音符的精确位置(例如,当录制的吉他失真时)。
● To check the frequency at which a track's sounds are peaking for possible conflict with other tracks, or to identify precisely where frequencies may need to be EQ'd.
● 检查轨道声音的峰值频率是否可能与其他轨道冲突,或准确识别可能需要均衡频率的位置。
● To check (for example) bass instruments for notes that are too quiet or too loud.
● 检查(例如)低音乐器是否有个别音符比预期的声音小或响亮。

Use the Options, Peak display mode, Show spectral peaks command to turn the display of peaks on and Options, Peak display mode, Normal peaks to turn them off. Another peaks display mode option is to Show spectrogram: this will be considered in the next section.
使用“选项”--“峰值显示模式”--““显示光谱峰值”命令打开峰值显示,使用“选项”--“峰值显示模式”--“显示标准峰值”来关闭它。另一个峰值显示模式选项是“显示频谱图”,这将在下一节中考虑。
Use the command View, Peaks Display Settings to open the window shown here (right).
使用“视图”--“峰值显示设置”命令打开如下所示的窗口(右侧)。
● You can use the Display mode dropdown to select Peaks, Spectral Peaks, Spectrogram or Spectrogram + Peaks. Note that this and other settings are global and will apply to all open projects.
● “显示模式:”,您可以使用显示模式下拉菜单选择“峰值”、“光谱峰值”、“频谱图”或“频谱图+峰值”。请注意,此设置和其他设置是全局设置,将应用于所有打开的工程。
● There is an option to display peaks to sqrt-scale.
● 有一个以平方根为单位显示峰值的选项。
● The Display gain slider can be used to increase or decrease the peak height, but do not affect volume.
● 显示增益滑块可用于增加或减小峰值高度,但不影响音量。
● In any mode except Peaks, right-click on the color display to open a context menu. Options include:
● 在除峰值之外的任何模式下,在颜色显示上单击鼠标右键以打开上下文菜单。备选方案包括:
Load spectogram preset: to select a saved set of settings.
加载光谱预置: 选择一组已保存的设置。
Save spectogram preset: saves current settings as a preset.
保存光谱预置: 将当前设置保存为预置。
Reset to defaults: resets settings to their default value.
重置为默认值: 将设置重置为其默认值。
Reverse spectrum :reverses the color spectrum.
反转频谱: 反转频谱的颜色。
Clamp hue at maximum brightness.
以最大亮度锁住色相。
● The four horizontal faders freq log, curve, contrast, and bright can be used to modify the display - e.g. to emphasise low frequencies, drag the freq log fader fully to the right.
可以通过调整频率对数、曲线、对比度和亮度这四个水平推子,来修改显示。例如,要更好地强调低频,请将频率对数推子完全向右拖动。
Enabling spectral peaks will roughly double peak file size. Generating these peaks uses a lot of RAM, especially if spectral peaks are displayed while recording. Spectral peaks can be enabled/disabled on a per track basis via a Track performance option (Prevent spectral peaks/spectrograms) on the right-click TCP context menu.
启用“光谱峰值”,将使峰值缓存文件的大小大致加倍。生成这些峰值,会占用大量RAM,尤其是在录音时显示光谱峰值的情况下。右键单击TCP,通过上下文菜单中的“轨道性能”选项(“阻止光谱峰值/频谱图”),可以按每条轨道来启用/禁用“光谱峰值”。
Options on the Media page of Preferences which affect spectral peak behaviour include Always generate spectral peak information. However, enabling this option can considerably increase RAM usage.
首选项的媒体页面上影响光谱峰值行为的选项包括“总是生成光谱峰值信息”。但是,启用此选项可以显著提高RAM使用率。
Peak Display Controls
峰值显示控件
In order to use this tool effectively you will need to understand and master its various controls. For example, if you are focussing on low end rumble you will probably want the display to focus on the lower end of the frequency spectrum. If dealing with high end resonance, you will wish to concentrate on higher frequencies. Here is a summary of the controls available, in many cases by clicking and dragging your mouse. Getting to grips with them all can be a bit tricky at first … you always have the Reset to defaults option!
为了有效地使用该工具,您需要了解并掌握它的各种控件。例如,如果您关注的是低频隆隆声,您可能希望显示器聚焦于频谱的低频。如果要处理高频共振,您将希望专注于更高的频率。以下是可用控件的摘要,在许多情况下,是通过单击并拖动鼠标来实现的。一开始,掌握它们可能有点棘手,…。您始终具有重置为默认值选项!
A media item is made up of a whole range of frequencies (as can be seen, for example, if you place, say, ReaEq in a track's FX chain). Spectral peaks are used to identify only the most dominant frequency at any point in time.
媒体对象由整个频率范围组成(例如,可以看到,如果您将ReaEq插在轨道的FX链中)。光谱峰值仅用于识别任何时间点的最主要频率。
The Frequency Range (20hz to 10khz)
频率范围(20 Hz至10 KHz)
The display is divided into seven frequency bands. To adjust how the frequency range is divided between these bands, click and drag the mouse left or right on the border between any two bands. Dragging right helps you focus on higher frequencies, left on lower ones.
显示器分为七个频段。要调整频率范围在这些频段之间的划分方式,请在任意两个频段之间的边界上单击并向左或向右拖动鼠标。向右拖动可帮助您关注较高的频率,向左拖动可将注意力集中在较低的频率上。
To adjust all colors used in the display, click and drag left or right over the color display.
要调整显示中使用的所有颜色,请在颜色显示上单击并向左或向右拖动。
To adjust only low colors, click and drag on left edge of color display.
若要仅调整低频段颜色,请单击并拖动颜色显示的左侧边缘。
To adjust only high colors, click and drag on right edge of color display.
若要仅调整高频段颜色,请在颜色显示的右边缘单击并拖动。
Double click to restore the default display.
双击可恢复默认显示。
Presets
预置
The Save spectral view and Load spectral view commands allow you to save and recall up to ten configurations as presets. The first five of these can also be loaded using actions (and therefore can be added to custom toolbars and/or menus, and/or be assigned keyboard shortcuts.)
“保存光谱视图”和“加载光谱视图”命令,允许您将最多10个配置保存和调用为预置。其中的前五个也可以使用操作列表加载(因此可以添加到自定义工具栏和菜单,或分配键盘快捷键。)
Spectrogram + Peaks Mode
频谱图+峰值模式
In spectogram + peaks mode, media items are displayed as both peaks and spectograms, as shown on the right.
在频谱图+峰值模式下,媒体对象同时显示为峰值和频谱图,如右图所示。
Spectral Peaks Mode
光谱峰值模式
In spectral peaks mode, media item waveforms are colored dynamically according to the dominant frequency.
在光谱峰值模式中,媒体对象波形根据主要频率动态染色。
By default, the color spectrum occupies the whole frequency range. You can change this, for example, to use the entire color range for each individual octave: this can help you to focus on much smaller variations in frequency.
默认情况下,颜色频谱占据整个频率范围。例如,您可以对此进行更改,以便为每个单独的倍频程使用整个颜色范围:这可以帮助您将注意力集中在频率上的小得多的变化上。
As an example, both of these images (below left) depict the same media item. The first (top) example uses Set range to full spectrum. The second example uses Set range to full spectrum every octave.
举个例子,这两张图片(左下角)描绘的是同一个媒体对象。第一个(顶部)示例,设置范围到全频谱。第二个示例,使用“在每个倍频程设置范围到全频谱”。
These options are available on the right-click context menu (shown above right). A Reverse spectrum option is also available.
这些选项在右击上下文菜单(如右上所示)中可用。还提供“反向频谱”选项。
Spectrogram Mode
频谱图模式
In this mode, media items are displayed as a spectogram. You can use for spectral editing.
在此模式下,媒体对象显示为频谱图。您可以用来进行光谱编辑。
The display faders (freq log, curve, contrast and bright) are useful here, especially the freq log control. Here is an example:
显示频率对数、曲线、对比度和亮度的推子,在这里很有用,特别是频率对数控件。下面是一个例子:
Shown here is the same media item with freq log set to 0.0 (left), 5.0 (center) and 10.0 (right). Notice that in the third image, the lower frequencies take up about half the area of the display.
此处显示的是相同的媒体对象,频率对数设置为0.0(左)、5.0(中)和10.0(右)。请注意,在第三幅图像中,较低的频率约占显示屏面积的一半。
