Usage   用法

Here follows a complete explanation for every control in LabChirp.
以下是对 LabChirp 中每个控件的完整说明。

Overview  概述

Sounds in LabChirp are generated based on the parameters found inside the Wave tab. Up to eight channels can be edited individually. Additionally, effects can be applied to the sound from the Effects tab.
LabChirp 中的声音是基于波形标签页中的参数生成的。最多可以单独编辑八个通道。此外，还可以通过效果标签页对声音应用效果。

Channels  通道

To the right you will see eight buttons corresponding to the different channels. Each channel generates an output based on its individual parameter settings defined in the Wave tab. When the sound is generated, the output of each enabled channel is combined.
右侧您会看到八个对应不同通道的按钮。每个通道根据其在波形标签页中定义的独立参数设置生成输出。当声音生成时，所有启用通道的输出将被混合。

To edit the parameters of another channel, switch to it by clicking on the button with the channel's number. Make sure the channel is enabled if you want it included in the sound.
要编辑其他通道的参数，请点击对应通道编号的按钮切换到该通道。若希望该通道包含在生成的声音中，请确保其处于启用状态。

To enable (unmute) a channel, check the box next to that channel's button.
要启用（取消静音）某个通道，请勾选该通道按钮旁的复选框。

You can copy elements from one channel to another using the controls below the column of channel buttons. See Copy channel for more information.
您可以使用通道按钮列下方的控件将一个通道的元素复制到另一个通道。更多信息请参阅“复制通道”功能说明。

Wave tab  波形选项卡

The Wave tab is where you edit a channel's parameters that define its output.
波形选项卡用于编辑通道的输出参数。

At the top, you will see settings for Length and Delay.
顶部可见长度（Length）和延迟（Delay）的设置项。

Length:

The length of the channel's output. One length value is equal to 1/22050 seconds (one sample for 22050 Hz and two samples for 44100 Hz). You can also input the length in seconds by clicking on the value shown to its right.

Delay:

How much silence is added before the channel's output starts. Same unit as Length.

长度（Length）：通道输出的时长。1 个长度值等于 1/22050 秒（22050Hz 采样率下为一个样本，44100Hz 下为两个样本）。也可通过点击右侧显示值直接输入秒数。延迟（Delay）：通道输出开始前插入的静音时长。单位与长度相同。

Below the Length and Delay settings are three different groups of controls, labeled Main wave, Frequency modulation and Volume modulation. These are the basic waves that make up the channel's output. See Waves below for details.
在“长度”和“延迟”设置下方有三组不同的控制选项，分别标记为“主波形”、“频率调制”和“音量调制”。这些是构成通道输出的基础波形。详情请参阅下文“波形”部分。

Below these controls, you will see the Envelope/Custom wave edit box. This is where you define the nine different envelopes/custom waveforms for the different waves. To switch envelope, click on the button to the left of the slider corresponding to the value whose envelope you wish to define. To define a custom waveform, click the button below the corresponding waveform selector on the right side. See Envelopes below for more details.
在这些控制选项下方，您会看到“包络/自定义波形”编辑框。此处可定义九种不同的包络/自定义波形以对应不同波形。切换包络时，点击滑块左侧对应目标参数的按钮；定义自定义波形时，点击右侧波形选择器下方的对应按钮。详情请参阅下文“包络”部分。

Effects tab  效果标签

Click OK to save your settings ("settings.cfg" will be created in the same directory as "LabChirp.exe").
点击"确定"保存设置（将在 LabChirp.exe 同目录下生成"settings.cfg"文件）。

Quality  质量

22050 Hz/44100 Hz  22050 赫兹/44100 赫兹

Hertz (Hz) determines the sample rate (values per second) of the output sound. Higher sample rate allows for higher frequencies and better sound fidelity.
赫兹（Hz）决定了输出声音的采样率（每秒采样值）。更高的采样率能支持更高频率的声音，并提升音质保真度。

8-bit/16-bit  8 位/16 位

Bit depth determines the resolution of the samples. An 8‑bit sound has a resolution of 256 values per sample, while a 16‑bit sound has 65536 values per sample. Higher resolution allows for finer detail. You can clearly hear a difference for instance at the end of long fade outs.
位深度决定了采样的分辨率。8 位音频每个采样有 256 个值，而 16 位音频每个采样有 65536 个值。更高的分辨率能呈现更精细的细节。例如，在长渐弱结尾处，你可以明显听出差异。

Trim silence  修剪静音

Leading:

This option will remove all silence at the beginning of your sound.

Trailing:

This option will remove all silence at the end of your sound.

前导：此选项将移除音频开头所有的静音部分。后导：此选项将移除音频末尾所有的静音部分。

Dither  抖动处理

With a limited resolution, the program needs to round a generated value to fit the resolution. Imagine a really quiet sine wave with values ranging from -0.4 to +0.4. If the rounding is consistent, all its values will be rounded to 0.
由于分辨率有限，程序需要对生成的值进行四舍五入以适应分辨率。想象一个非常微弱、幅值在-0.4 到+0.4 之间的正弦波。如果采用一致的舍入方式，其所有值都会被舍入为 0。
Dither is basically inconsistent rounding, to get a more accurate average representation, so you can still hear the wave even after you really shouldn't be able to with the current resolution. Although it can be a bit noisy.
抖动本质上是非一致的舍入方式，以获得更精确的平均值表现，这样即使在当前分辨率下本应听不见的波形仍能被感知。不过可能会带来些许噪声。

There are two different methods of dither in LabChirp:
LabChirp 中有两种不同的抖动方法：

Floyd-Steinberg

simply forwards the rounding error to the next sample and adds it to its value, which gives a very even and reliable estimation of the sound. May however in some cases result in audible artifacts.

Noise

adds a really subtle noise to the sound, making the rounding more chaotic. Results in no audible artifacts.

Floyd-Steinberg 方法简单地将舍入误差传递给下一个样本并叠加到其值上，从而提供非常均匀可靠的音频估计，但在某些情况下可能导致可听伪影。噪声法则为音频添加极其微妙的噪声，使舍入过程更随机，不会产生可听伪影。

Keep in mind that dither is not guaranteed to improve the quality of the sound, and may add unwanted noise. Experiment and use your own judgement!
请注意，抖动处理并不能保证提升音质，反而可能引入不必要的噪音。请自行试验并运用您的判断力！

Oversampling  过采样

Oversampling can greatly improve the quality of the sound. It is especially noticeable with sounds featuring sharper waveforms, like saw and square, at high frequencies.
过采样能显著提升音质，尤其对于高频段锯齿波、方波等波形尖锐的声音效果更为明显。
With oversampling, each sample will become an average of adjacent values between the previous sample and the next. This gives a much better representation of the actual value.
通过过采样，每个采样点将成为前后相邻样本间的平均值，从而更精准地反映实际数值。
A higher setting means better quality, as more adjacent values are gathered per sample, but the sound will take longer to generate.
数值设置越高意味着音质越好，因为每个采样点会采集更多相邻数值，但生成声音所需时间也会更长。

Note that dither and oversampling does not affect the output sound's file size.
请注意，抖动处理和过采样不会影响输出声音的文件大小。

Waves  波形

Sound in LabChirp is generated through wave calculations. Three waves each play a different role in creating the sound:
LabChirp 中的声音是通过波形计算生成的。三种波形在声音创作中各司其职：

Main wave:

The basic wave of your sound.

Frequency modulation:

Modulates ("vibrates") the pitch of the main wave.

Volume modulation:

Modulates the volume of the main wave.

主波形：声音的基础波形。频率调制：对主波形的音高进行调制（“振动”）。音量调制：对主波形的音量进行调制。

Wave parameters  波形参数

Each wave has its own frequency, volume/amplitude, waveform and waveform offset:
每个波形都有其自身的频率、音量/振幅、波形及波形偏移量：

Frequency

determines how fast the wave will repeat (in Hz).

Volume/amplitude

determines the strength of the wave.

Waveform

is the shape of the wave. There are eight different waveforms to choose from, including a user defined Custom wave. These are selected from the waveform selector to the right. Try them out to hear the difference!
频率决定波形重复的快慢（以赫兹为单位）。音量/振幅决定波形的强度。波形即波的形状。共有八种不同波形可选，包括用户自定义的自定义波形。这些可通过右侧的波形选择器进行选择。试听它们以感受差异！
To edit the Custom waveform, click the Custom button below the waveform selector. See Envelopes below for details on how to edit envelopes and custom waveforms.

Offset

is adjusted using the slider below the waveform selector. This determines the offset/phase of the waveform. This can be useful for a bit more advanced sounds.
要编辑自定义波形，请点击波形选择器下方的“Custom”按钮。关于如何编辑包络和自定义波形的详细信息，请参阅下方的“Envelopes”部分。偏移量通过波形选择器下方的滑块进行调整，这决定了波形的偏移/相位。此功能对制作稍复杂的声音效果很有帮助。
When Noise or Noise2 is selected, offset instead determines the random seed for the noise generation.
当选择“Noise”或“Noise2”时，偏移量将改为决定噪声生成的随机种子值。

Note that the frequency slider stops at 3000 Hz for the Main wave, and at 1000 Hz for modulation waves, but all can reach up to 9999.99 Hz by manually entering a value into the text box to the right of the slider, or by using the buttons around the slider.
请注意，主波的频率滑块最高可调至 3000 Hz，调制波则为 1000 Hz，但通过手动在滑块右侧的文本框中输入数值或使用滑块周围的按钮，所有波形均可达到 9999.99 Hz。

Envelopes  包络线

With envelopes, you can freely control a parameter of the sound over time. A simple example would be to make the frequency gradually increase, or the volume lower and lower (like a fade-out), but you can give the envelope any shape you want.
通过包络线，您可以自由地控制声音参数随时间的变化。一个简单的例子是让频率逐渐升高，或音量越来越低（如淡出效果），但您也可以自定义任意形状的包络线。
The envelope editor is also used to create custom waveforms, where the graph instead represents the shape of the wave.
包络编辑器还可用于创建自定义波形，此时曲线图代表的是波的形状。

Main wave, Frequency modulation and Volume modulation have two envelopes and one Custom wave each.
主波形、频率调制和音量调制各有两个包络线和一个自定义波形。

Volume/Amplitude:

This changes the volume or amplitude of the wave over time.

Frequency:

This changes the frequency of the wave over time.

Custom wave:

This lets you create your very own waveform! Be sure to have the Custom waveform selected in the waveform selector.

音量/振幅：这会随时间改变波的音量或振幅。频率：这会随时间改变波的频率。自定义波：这让你可以创建自己的波形！确保在波形选择器中选择了自定义波形。

Select the envelope you want to edit by clicking the button to the left of the slider for that parameter. To edit custom wave, click the button located below the waveform selector.
通过点击参数滑块左侧的按钮选择要编辑的包络线。若要编辑自定义波形，请点击波形选择器下方的按钮。
After having selected the envelope, use the envelope panel to edit the points of the envelope.
选择包络后，使用包络面板编辑包络的点。
The text above the envelope panel will indicate which envelope is currently selected.
信封面板上方的文本将指示当前选中的是哪个信封。

Editing the envelopes  编辑包络线

The following two methods can be used to edit the points of the envelope. Choose the one you prefer in the Settings.
以下两种方法可用于编辑包络线的点。在设置中选择您偏好的方式。

Mode A:  模式 A：

  要选中一个点，在其上或附近右键点击。也可使用 Shift + Left 或 Shift + Right 分别选择前一个或后一个点。
• You can move the selected point a single step using the Arrow keys for more precision. Holding Ctrl will move it five steps.
  您可以使用 Arrow keys 微调移动选中点一个步长。按住 Ctrl 则移动五个步长。
• To add a point to the envelope, click + to the right (or Numpad+/Insert) and a point will be added between the currently selected point and the next one. Note that no point can be created with the last point selected.
  要在包络线上添加一个点，请点击右侧的+号（或 Numpad+ / Insert ），系统会在当前选中点与下一个点之间新增一个点。请注意，当最后一个点被选中时无法创建新点。
• To remove a point from the envelope, click - to the right (or Numpad-/Delete) and the currently selected point will be removed. Note that the first and last point of the envelope cannot be removed.
  要从包络线上移除一个点，请点击右侧的-号（或 Numpad- / Delete ），当前选中的点将被删除。注意：包络线的首尾端点不可删除。

Move the effect up or down in the list. You can also use the title bar to drag and drop the effect to the desired position.

Remove (X):

Remove the effect from the list.

折叠/展开（˅/˃）：用于折叠或展开效果面板内容，节省视觉空间。启用/禁用（☑）：启用或禁用效果。若取消勾选，该效果将被忽略/不应用。上移/下移（↑/↓）：调整效果在列表中的顺序。也可通过标题栏拖放效果至目标位置。删除（X）：从列表中移除该效果。

Inside an effect panel, on its right side, there are eight checkboxes numbered 1 through 8. If "Apply to all channels" is unchecked, these checkboxes determine which channels the effect will be applied to.
在效果面板右侧内部，有编号 1 至 8 的八个复选框。若未勾选"应用到所有通道"，这些复选框将决定效果应用的特定通道。

All effect types are different, and thus each have their own set of parameters:
所有效果类型各不相同，因此每种类型都有其专属参数集：

Echo  回声

Adds a set number of repetitions over the sound, with a given delay and decay value.
在声音上添加指定次数的重复，带有给定的延迟和衰减值。

Delay:

The delay between each repetition in milliseconds.

Decay value:

The relative volume for each repetition.

Iterations:

The number of repetitions to add over the sound.

延迟：每次重复之间的间隔时间，单位为毫秒。衰减值：每次重复的相对音量。迭代次数：在声音上添加的重复次数。

Reverb  混响

This effect makes the essence of the sound linger for a while, simulating the acoustics of a large room.
这种效果让声音的本质萦绕片刻，模拟出大房间的声学特性。

Room size:

An arbitrary size of the "room" the sound echoes through. Larger values means longer decay times.

Wet/dry:

How much of the original sound is heard. A value of 0 means that only the reflections will be heard, while 100 means only the original sound is heard.

房间大小：声音在其中回响的“房间”的任意尺寸。数值越大，衰减时间越长。湿/干比例：原始声音的听取量。值为 0 时仅听到反射声，100 时则仅听到原始声音。

Overdrive  过载

Boosts the volume of the sound, but limits any parts exceeding the original maximum volume, resulting in a louder and grittier sound without actually increasing the volume.
提升声音音量，但会限制超过原始最大音量的部分，从而在不实际增加音量的情况下产生更响亮且粗糙的音效。

Amount:

How much to amplify the original sound before limiting.

Soft:

Determines whether or not the sound will be hard clipped, or receive a softer treatment where the wave values are gradually limited approaching the clipping edge.

增益量：限制前对原始声音的放大程度。柔和：决定声音是进行硬削波，还是采用更柔和的处理方式，在接近削波边缘时逐步限制波形值。

Flanger  镶边效果器

Adds a slightly slower or faster copy over the sound, which results in a sweeping effect.
在原始声音上叠加一个稍慢或稍快的副本，从而产生扫频效果。

Speed:

How much the speed of the copy is increased or decreased. Values further from 0 results in a faster sweep.

Offset:

The original offset of the copy.

Inverted:

With this checked the copy will be inverted, or "upside down", resulting in a different and often more distinct sweeping sound.

速度：副本速度增减的幅度。数值越远离 0，扫频速度越快。偏移量：副本的初始时间偏移。反相：勾选此项后副本将反相（即波形上下颠倒），产生更独特且明显的扫频音效。

Chord  和弦

Combines several pitch-shifted versions of the sound. Note that the pitch is different, but the length remains the same.
结合了多个经过音高偏移处理的音频版本。注意音高不同，但时长保持不变。
You can have four voices with different pitches and volumes at once.
可同时设置四个不同音高和音量的声部。

Relative note (leftmost control):

How many semitones this voice will be pitched up or down.

Volume:

The volume for this voice. Set to 0 to disable.

相对音高（最左侧控件）：该声部音高升降的半音数。音量：此声部的音量，设为 0 可禁用。

Bitcrusher  位压缩器

This effect will reduce the apparent resolution of your sound, to achieve a more lo-fi or "retro" sound.
此效果会降低声音的表观分辨率，以实现更低保真或“复古”的音效。

Note that Bitcrusher does not affect the actual bitrate of the sound file.
请注意，位压缩器不会影响声音文件的实际比特率。

Depth:

Determines the amount of available values per sample the resulting sound will have, in bits. 8 bits means 256 values, 4 bits means 16 values and so on. You can even enter a non-integer value, such as 2.6 bits, to get 6 values.

Sample rate:

Determines how many samples per second the resulting sound will have.

Dither:

Adds noise to the input sound to eliminate consistent rounding. See a more detailed explanation of dither under Quality above.

Center:

With an even number of available values, there will be an equal amount of positive and negative values, but none at 0. With this option unchecked, the values will instead be shifted so that one of them will be at 0.
深度：决定处理后声音每个采样点可用的数值范围，以比特为单位。8 比特表示 256 个值，4 比特表示 16 个值，以此类推。您甚至可以输入非整数值，如 2.6 比特，将得到 6 个值。采样率：决定处理后声音每秒的采样点数。抖动：向输入声音添加噪声以消除持续性的舍入误差。关于抖动的更详细解释，请参阅上文“质量”部分。居中：当可用值为偶数时，正负值数量相等但不含零值。取消勾选此选项时，数值将偏移以确保其中一个值位于零点。
With an uneven number of available values, there will always be one at 0, so in that case this option does nothing.
当可用值为奇数时，总会有一个值处于 0 位置，因此在这种情况下此选项不起作用。

Mutator  变异器

If you want to slightly change something with your sound but you are not sure exactly what, you can use the Mutator.
若您想对声音进行微调但不确定具体调整方向，可使用变异器功能。
Click the Mutator button below the channel buttons to open the Mutator. Adjust the sliders to determine how extreme the mutation of each element will be.
点击通道按钮下方的"变异器"按钮打开界面，通过滑动调节条控制各元素的变异强度。
When you click Mutate!, the parameters of your sound will change randomly.
点击“突变！”按钮时，您的声音参数将随机变化。
You can apply the mutation to all enabled channels or only the selected channel.
您可以将突变应用于所有启用的通道或仅选定的通道。

Randomizer  随机生成器

If you are lazy, in a hurry, or find everything in this manual confusing, you can use the Randomizer to let LabChirp generate a sound for you!
如果您觉得懒散、时间紧迫，或对本手册的所有内容感到困惑，可以使用随机生成器让 LabChirp 为您生成声音！
Click the Randomizer button below the channel buttons to open the Randomizer.
点击频道按钮下方的随机生成器按钮即可打开随机功能。
To quickly generate a random sound, simply select one of the presets and click Randomize!.
要快速生成随机音效，只需选择一个预设并点击“随机生成！”按钮。
This will overwrite any current sound you might be working on, so remember to save before randomizing!
这将覆盖您当前可能正在编辑的音效，因此请记得在随机生成前保存！

With the arrow buttons (< and >) next to the Randomize! button, you can re-generate a previously generated sound. Useful if you heard a cool sound but accidentally generated a new one.
通过“随机生成！”按钮旁的箭头按钮（< 和 >），您可以重新生成之前生成的音效。当您听到一个很棒的音效却不小心生成了新音效时，这个功能非常实用。

You can also create and save your own presets!
您还可以创建并保存自己的预设！
The <New> preset has all parameters set to create the default sound, and is a good starting point for creating a new preset from scratch, but any preset can be edited.
<新建>预设将所有参数设为默认声音配置，是从零开始创建新预设的理想起点，但任何预设均可编辑。
The different tabs contain settings for the random generation. These settings can be saved by typing a name in the preset selector and clicking Save.
不同标签页包含随机生成的设置。通过在预设选择器中输入名称并点击保存，即可存储这些设置。

Main  主界面

In this tab you can set the range for most of the controls in the Wave tab, and the number of channels to be randomized. For instance, if you set Main Frequency to Minimum 100 and Maximum 200, the main frequency value of the generated sound will be somewhere between 100 and 200.
在此选项卡中，您可以设置波形选项卡中大多数控件的取值范围以及需要随机化的通道数量。例如，若将主频率最小值设为 100、最大值设为 200，则生成声音的主频率值将介于 100 至 200 之间。

Waveforms  波形

Select all waveforms to be included in the randomization for each wave. For instance, if you only want Noise, have only that selected.
为每个波形选择参与随机化的所有波形类型。例如，若仅需噪声波形，则只勾选该选项。
"Custom" will generate a random Custom wave.
"自定义"选项将生成随机自定义波形。

Envelopes  信封

In this tab, you can adjust how the different envelopes will be generated.
在此选项卡中，您可以调整不同包络线的生成方式。

Start:

Determines the position of the first point. For instance, if you want it to start at the top always, set both Minimum and Maximum to 100. To have it start somewhere between 20 and 50, set Minimum to 20 and Maximum to 50.

Next X:

Determines how far a new point will be placed from the previous in the horizontal (temporal) axis. "1" means it will be created only one step from the previous, and "500" means it will be created all the way at the end.

Next Y:

Determines how far up or down a new point will be placed relative to the previous. For instance, to make the envelope tend downwards, set the Minimum and Maximum value to something negative.

起始点：决定第一个点的位置。例如，若希望始终从顶部开始，请将最小值和最大值均设为 100。若要在 20 至 50 之间随机起始，则将最小值设为 20，最大值设为 50。下一个 X：决定新点与前一水平（时间）轴上的距离。"1"表示仅与前一点相隔一步，"500"表示将直接创建在末端。下一个 Y：决定新点相对于前一点在垂直方向上的偏移量。例如，要使包络线呈下降趋势，可将最小值和最大值设为负数。

Hovering any of the colored areas to the left will display randomized previews for that envelope generated with the current parameters.
将鼠标悬停在左侧任何彩色区域上，将显示基于当前参数随机生成的该包络线预览。

Effects  效果

Effects can be added to a preset using the Add effect... button. Adjust the number next to the effect's name to determine the probability in percent that the effect will be added to the sound.
可通过点击“添加效果...”按钮将效果加入预设。调整效果名称旁边的数值，以百分比形式设定该效果被添加到声音中的概率。
All effects have their own minimum and maximum values for their specific parameters. For on/off parameters, a numeric value is used to determine the probability of the parameter's checkbox being checked.
所有效果都有各自参数的最小值和最大值。对于开关型参数，使用数值来确定该参数复选框被勾选的概率。

Batch save  批量保存

Click the Batch save... button in the Randomizer or Mutator window to open the Batch save dialog. This allows you to generate several randomized/mutated sounds at once, based on the current Randomizer or Mutator settings.
在随机化器或变异器窗口中点击“批量保存...”按钮，即可打开批量保存对话框。此功能允许您根据当前随机化器或变异器的设置，一次性生成多个随机化/变异后的声音。

Select the number of sounds to generate, and their file type (LCH and/or WAV), then click Save.... In the save dialog that appears, browse to the desired save location and input a base file name, and save. The generated files will use this name as a prefix, followed by a number.
选择要生成的声音数量及其文件类型（LCH 和/或 WAV），然后点击保存...在出现的保存对话框中，浏览至目标保存位置并输入基础文件名后保存。生成的文件将以此名称作为前缀，后接数字编号。
