Ardour4 初学者教程 02 开始入门

启用JACK

（原文）

Ardour 4.X版不再要求您在您的系统上安装有JACK（JACK音频连接工具包）。但是您可能想启用JACK以便让Ardour可以与其他Linux音频应用程序共享音频和MIDI。如果您想知道JACK究竟是什么，请参考这个页面： http://ardour.org/jack

如果您不打算在Ardour里使用JACK，您可以跳过这一节内容，否则请继续阅读。

简而言之，JACK是一个音频系统，用于在您的计算机上管理Ardour和您的电脑的声卡之间的联系，以及Ardour与其他启用了JACK音频程序之间的联系。Ardour过去一直是要求必须运行JACK，但自从4.0版本开始这变成可选项。

更多关于JACK的信息请参考 http://jackaudio.org/ 以及 http://jackosx.com/

在Ubuntu系统上，您可以使用Qjackctl或者Cadenc去启动和停止JACK，并且控制它的设置。如果您有一个配置恰当的KXStudio安装版，JACK也许已经运行在系统后台中了。如果没有，您可能必须手工启动它。

在苹果Mac系统上，您将需要使用JackPilot。这个页面也许对您有所帮助： http://en.flossmanuals.net/ardour/ch005_installing-jackosx/ （警告：页面具体内容可能已经过时了。我们始终希望能像本教程这样在包括一个更新页面。)

使用Cadence（Linux系统）

Launch Cadence. If JACK is already running, you will see a window like this:

More info on Cadence: http://kxstudio.sourceforge.net/Documentation:Manual:cadence_introduction

使用Qjackctl（Linux系统）

如果使用Qjackctldi替代，看起来就会像这样：

如果您仍未运行，使用“设置Setup”按钮去配置JACK，然后点击“开始Start”去启动JACK。

使用JackPilot（苹果OS X系统）

请参考这个页面： http://en.flossmanuals.net/ardour/ch013_starting-jackosx/ （警告：页面具体内容可能已经过时了。放这个链接在此只是作为一个起点。我们始终希望能像本教程这样在包括一个更新页面。)

JACK设置

要了解更多的Jack配置信息，请参考： http://kxstudio.sourceforge.net/Documentation:Manual:jack_configuration （使用Cadence讲解，但基本信息同样适用于Qjackctl的设置窗口）。

启动Ardour

（原文）

很简单，点击Ardour图标即可启动程序。

在Ubuntu系统，您可以使用在Dash分类菜单里找到该软件的启动器。按下“Super”超级键（即“Windows”窗口键），（或者按下“Super” + “A”键直接打开Dash应用分类）然后输入“Ardour”，然后你可以就找到并点击Ardour图标启动程序。如果Ardour是显示的第一个搜索结果，简单回车也可以启动它。

点击Ardour-4即可启动程序。

（注：在UbuntuStudio系统，您可以点击左上角任务栏主菜单，在"音频制作Audio Production"子菜单里就能找到Ardour。）

一旦您启动了Ardour，接下来就会出现会话设置Session Setup窗口。

您可以点击新会话New Session按钮创建一个全新的会话，或者你使用下方的最近的会话Other Sessions选项，可以打开一个已经存在的回话。现在让我们创建一个新的会话，点击新建会话New Session按钮，会弹出一个窗口如下图所示。

为您的新建工程输入一个名字，点击打开Open 。

• 提示：命名会话时，避免使用除字母和数字以外的任何字符（可以使用中文）。避免使用空格、带音标或重音的字母、!@#$%*()+、句号、逗号等。如果您喜欢，可以使用破折号或下划线。例如，以其命名为“My Great Session!”，不如命名为“My_Great_Session”，或者“MyGreatSession”，或者“my-great-session”。不要用“Açaí”这名字，可以改为“Acai”（没有带音标或重音的字母）等诸如此类。一旦您创建了您的Ardour会话，不要手动重命名属于这个会话的任何文件夹或文件。

开启一个会话

（原文）

Ardour将对您在会话Sessions里的工作进行分组打包。一个会话是一组音轨Tracks,，最终可能会被混音成一个单声道、立体声或多声道声音文件。会话实质上就是工程，您所有的数据都被保存在这一个单独的会话文件夹中。

当您启动Ardour，您会看到一个提示窗问您是否启用一个新会话，或者打开一个已经存在的会话。当您创建一个新会话时，您必须为它起个名字。

• 提示：命名会话时，避免使用除字母和数字以外的任何字符（可以使用中文）。避免使用空格、带音标或重音的字母、!@#$%*()+、句号、逗号等。如果您喜欢，可以使用破折号或下划线。例如，以其命名为“My Great Session!”，不如命名为“My_Great_Session”，或者“MyGreatSession”，或者“my-great-session”。不要用“Açaí”这名字，可以改为“Acai”（没有带音标或重音的字母）等诸如此类。一旦您创建了您的Ardour会话，不要手动重命名属于这个会话的任何文件夹或文件。

您还需要为Ardour指定您想要把新会话文件夹存储在哪个目录下。

当您一切准备就绪，点击打开Open，Ardour将创建新会话，然后打开它。

高级选项

如果您单击小三角形打开高级选项Advanced Options‘’，您将可以通过以下选项对工程进行更细致的设置：

• 是否创建主控总线Master Bus（即：会话最终输出的音频）且包含有多少个声道channels。
• 是否自动把电脑音频接口（声卡）的输入连接到会话的声轨上，且需要使用几个声道。
• 是否自动连接到输出，是输出到主控总线或是输出到音频接口的输出，且需要使用几个声道。

如果您没有安装JACK到您的电脑里，或者它已经安装了但没有运行，在您的会话启动之前您将看到如下图所示的窗口：

主要选项有：

音频系统Audio System —— 您可以选择JACK（如果您已经安装有），或者选择您电脑里默认的音频系统（Linux系统是ALSA，苹果Mac系统是CoreAudio）。

驱动Device —— 或者是您的内置声卡，或者是你也许安装有的一个外置声卡（诸如：一个USB接口的声卡）。

采样率Sample Rate —— 48K或者44.1K是常用的选择。

（注：关于如何避免硬件延迟，选择UbuntuStudio系统有个好处就是，在开机启动菜单可以选择使用低延迟lowlatency的系统内核。）

如果您在启动Ardour之前就已经启动了JACK，你就不需要处理到这个窗口。

如果要在Audour已经启动后，再创建一个Ardour会话，选择菜单中的会话Session > 新建New。

界面概览

（原文）

本节将为您概括介绍Ardour的基本界面。

我们将看一下编辑器窗口Editor Window和混音器Mixer Window窗口。在此列出的各项功能将会在后面的章节中介绍更多的细节信息。

编辑器窗口

当您创建一个新的会话之后，Ardour会打开一个空的新窗口即编辑器窗口Editor Window。在Ardour里，编辑器窗口是最重要的窗口，因为在此你不但能够控制程序，而且还能查看和编辑您已经导录制或导入的音频。

位于编辑器窗口顶部的，是几个主要功能区：播送菜单Transport Menu，时钟Clocks，编辑模式/游标模式Edit Modes/Cursor Modes菜单，吸附模式Snap Mode菜单和附加控制Auxiliary Controls。下的共能区是主版面Main Canvas，包括了在会话中使用的音轨Tracks和总线Busses。音轨的混音栏Mixer Strips显示在左边，另一组用于概览的选项卡显示在右边，其中有：区域Regions，音轨/总线Tracks/Busses，快照Snapshots、编辑群组Edit Groups和模块Chunks。最底部的窗口是摘要Summary视图view，这是一个小型的时间线视图，可以在整段会话中快速导航。

我们将在这里简略介绍这些控件，而在后续章节将会专门详细地讲解它们。

播送菜单

播送菜单Transport Menu的控制包括以下按钮：

中文	快捷键	英文
MIDI重置	Ctrl+Alt+P	MIDI Panic
启用/禁用音频识别声（节拍器）	7 （大键盘数字键）	Enable/Disable audio click (metronome)
跳转到会话起点	Home/向左键	Rewind（原文有误，不是倒放）
跳转到会话终点	End/向右键	Fast forward（原文有误，不是快进）
循环播放	L	Loop playback
播放片段/选区		Play range/selection
从指针起播放	空格	Play from playhead
停止	空格	Stop
启用录音	Shift+R	Record-enable
推放/滑播（速度）控制	（鼠标拖动绿色方块）	Jog/shuttle controls

计时器

计时器位于播送控制的旁边。Ardour的计时器时可以显示4种不同的时间格式：时间码、小节：拍子、,分钟：秒、采样。右键点击计时器即可选择其中一种格式。您也可以关闭计时器。有两个播送计时器的原因是，它允许您以两个不同的时间单位查看指针的位置，而无需改变任何设置。

要了解关于计时器的更多细节，请参阅设置时间线章节。

编辑模式和游标模式

编辑模式Edit Modes和游标模式Cursor Mode控制定义主版幅的行为，以及指定不同功能的游标。在下拉菜单里有三种编辑模式：滑行Slide，波纹Ripple和锁定Lock。右边的智能Smart按钮是用于游标模式：

中文	快捷键	英文
智能模式	Y	Smart Mode
抓取模式	G	Grab Mode
范围模式	R	Range Mode
切割模式	C	Cut Mode
伸展模式	T	Stretch Mode
监听模式	（鼠标点按着不放）	Audition Mode
描绘模式	D	Draw Mode
内部编辑模式	E	Internal Edit Mode

它们中的大多数都是在区域常用操作这一章里详述。最后两个在使用自动化这一章里详述。

智能模式Smart Mode实际上是抓取模式和选区模式的组合。启用时，游标如果是在区域的上半部分时是“选区模式”，游标在下半部分时则是“抓取模式”。

（注：最右上角的向下箭头，点击它可以把工具栏提取出来成为一个单独的窗口，然后这个窗口可以移动放置在任意地方。同样，点击窗口里最右上角的向上箭头，或者点击窗口边框的X关闭按钮，可以把工具栏恢复到原位。）

吸附选项

吸附选项菜单控制着网格Snap Options、网格点Grid Points和编辑点Edit Point。请参见设置节拍Setting Up the Meter、使用范围Using Ranges和区域常用操作Working With Regions章节以了解更多的细节。

缩放选项

在游标模式Cursor Modes和吸附选项Snap Options之间的是缩放选项Zoom Options。在这里您可以限定缩放操作的行为。您可以使用标准的放大Zoom In（推进）和缩小Zoom Out（拉远）按钮，加上第三个被称为缩放到会话Zoom to Session的按钮（对于快速概览您的整个会话十分有用：它根据屏幕可用空间缩放显示整个会话）。

中文	快捷键	英文
放大	-	Zoom In
缩小	=	Zoom Out
缩放到会话	Shift+_	Zoom to Session

• 提示：使用快捷键 = （主键盘上的等于号）放大，使用快捷键 - （主键盘上的减号）缩小，使用快捷键 Shift +_ （主键盘上同时按着Shift键和减号键）缩放到会话。

接着的下拉菜单控制着缩放焦点Zoom Focus。它限定缩放操作的焦点。您可以尝试每一种不同的放大和缩小焦点。例如，选择指针（播放头）将导致以指针所在的位置为中心进行缩放。选择鼠标将以您当前鼠标的位置作为参考进行缩放，诸如此类。

（注：该菜单的选项有——左、右、中、指针、鼠标、编辑点）

接着的下拉菜单和最后两个按钮控制着“垂直缩放”。它们允许您在垂直方向上延展和收缩所有的音轨及总线。使用下拉菜单选择一个您想在屏幕上显示的特定音轨数量（注：即屏幕最多能同时显示多少个音轨）。使用那两个按钮可以延展和收缩所有音轨（或者如果已经有了一个选区，则仅针对已选中的音轨）。

辅助控制

想了解主界面上其它按钮的更多信息，请参考Ardour手册 http://manual.ardour.org/ 。

主版面

主版面略低于上述的控制按钮行。它基本上包含了标尺Rulers、音轨Tracks和总线Busses显示的空间、以及底部的摘要Summary视图view。

在Ardour的编辑器窗口（整个窗口的右上角）的最顶端，您可以发现非常有用的信息，例如会话的采样率，可用的记录时间，以及DSP使用率。（注：数字信号处理器Digital Signal Process）

标尺

右键点击标尺名称，您将看到一个菜单，列出的是可供您显示的所有标尺类型。您可以取消勾选您不需要的标尺勾选，以节省屏幕空间。更多的相关操作信息可以参考设置时间线Setting up the Timeline和设置节拍Setting up the Meter章节。

（注：菜单的选项有——分：秒、时间码、采样、小节&拍子、节拍、节奏、范围标记、循环/转切、CD标记、位置标记、视频时间线）

音轨和总线

标尺的下方显示的是音轨和总线。如下图所示，您可以看到一个总线名叫“Master”，以及一条音轨名叫“MyTrack”。其中MyTrack音轨包括了一个区域，其所显示的一个音频文件被描绘成它的波形。更多关于音轨和总线的信息请参考创建一条音轨或总线Creating a Track or Bus章节。

编辑器混音栏

编辑器混音栏位于编辑窗口的左边。它显示的是当前选中的音轨或总线的混音栏Mixer Strip信息。它控制着音量、插件以及与音轨和总线相对应的路由。您可以切换显示或隐藏编辑器混音栏，只需点击菜单视图View > 显示编辑器混音栏Show Editor Mixer （快捷键 “Shift +E”）。混音栏的更多信息请参考使用混音栏Using the Mixer Strip章节。

（注：下图为选中音轨后的混音栏显示状态）

区域、音轨/总线、快照、群组、范围、标记

在Ardour的编辑器窗口的右边区域，根据所选中的标签页不同，可以有5个不同的功能：区域Regions、音轨/总线Tracks/Busses、快照Snapshots、音轨和总线群组Track & Bus Groups、以及范围和标记Ranges & Marks。默认是区域标签页被选中。因此编辑器窗口的这部分通常被称为区域列表Regions List。区域所代表的音频文件存储在银盘上，可以直接把它从区域列表里拖到主版面的音轨上。想了解更多区域的信息可参考区域常用操作Working With Regions章节。音轨标签页的功能请参考安排音轨Arranging Tracks章节，快照标签页的功能请参考保存一个快照Saving a Snapshots章节。

混音器窗口控件

第二个窗口，Mixer Window 混音器窗口，点击主菜单的 Window 窗口 > Mixer 混音器 即可显示。

混音器窗口的主要功能是显示所有的混音栏，各个音轨并排显示，以便于参考。这个窗口主要应用于Mixing混音流程，它还提供了访问Plugins插件和其他Routing路由功能。若需要更的详细信息，请参阅理解路由、混音和使用插件章节。

这个窗口的左上角还包含有一个可见混音栏清单。这部分的复选框可以用来查看和隐藏不同音轨的混音栏。最后，还有一个区域来管理Groups群组。

切换窗口

您可以使用组合键 Alt + M（苹果Mac系统 Control + M）来切换窗口置顶：编辑器或混合器。

分离和重新放置工具栏

编辑器窗口的大部分工具栏是可以从编辑器窗口脱离开来，只需点击右上角白色向下的小箭头即可。

分离出来的工具栏在屏幕上将成为一个单独的窗口，而如果要重新放会编辑器窗口的原处，只需点击右上角白色向上的小箭头即可。

设置时间线

（原文）

因为不同的用户使用Ardour处理不同的工作，所在应用程序中，时间的衡量方式应当是可以变更的。

用户创建音频播放、纪录片、新闻报道或者环境音效可能希望使用Minutes分钟和Seconds秒，又例如，录制乐队或出品电子音乐将最有可能使用Bars小节和Beats拍子。视频出品则希望以一个视频帧每秒的Timecode时间码来操作，而那些希望极致精度的甚至可能希望使用Samples采样。所有这些方式都可以在Ardour中显示和使用，以此作为一种手段来组织您的区域和编辑。

主计时器和次计时器

Editor Window编辑器窗口顶部附近有两个计时器，以数字格式显示时间的格式：时间码，小节：拍子，分：秒和采样。右键点击这两个时钟的任意一个即可以更改它的格式。

这些被称为播送计时器。左边是播送计时器，右边是次播送计时器。有两个播送计时器的优点是您能够以在两个不同的时间单位看到指针的位置，而无需改变任何设置。

在这两个计时器的右边，您还可以看到一组5个计时器，用于显示当前已选择的范围和切换范围。关于时钟显示更多的信息请参阅Ardour手册。

吸附模式

Snap Mode吸附模式工具栏位于计时器下方靠右的地方。它们控制Quantization量化时间网格的方式，即：“吸附”一个音频Region区域到您所选择的网格类型。

当选中了No Grid无网格，可以在音轨内自由移动区域。当选中了Grid网格，区域将会“吸附”到最近的Grid Point.网格点。当选中了Magnetic磁性吸附，可以自由移动区域，但当它们被移动到非常接近一个网格点时，将会“吸附”到网格点。

中间的Units单位菜单用于选择以什么来作为网格点，例如拍子、小节、标记、分钟、秒、各种SMPTE时间码，或者或区域的边缘。

时间线

Timeline时间线位于吸附模式工具栏下方，主版面的正上方。通过在时间线上右键单击，您可以设置复选框，勾选希望显示的不同类型的时间信息。

分/秒

要在时间线上查看分和秒，右键点击时间线，然后选择Min分：Sec秒。您将能够以秒或者分来设置网格。

小节/拍子

要在时间线上查看小节和拍子，右键点击时间线，然后选择Bars小节 & Beats拍子。您将能够以小节\拍子或者多拍的简写，例如3、4、8、16或32。

不但可以为整个Ardour回话设置一个Meter节拍和Tempo节奏，还可以在同一个会话中的不同地方改变它们。有关这方面的更多信息，请参阅Setting Up the Meter设置节拍章节。

时间码

要想以SMPTE视频时间码进行工作，首先您需要设置Timecode时间码fps（帧每秒）。可以在会话属性窗口（菜单栏 Session会话 > Properties属性，或者快捷键 Alt + O）找到时间码标签页。

一旦您完成设置，请在时间线上右键点击，勾选Timecode时间码复选框，以确保您的时间码尺可见。你将能够以SMPTE Frames帧、SMPTE Seconds秒和SMPTE Minutes分设置网格。

创建一个音轨或一条总线

（原文）

什么是音频轨道？

一个Audio Track音频轨道就是一个您可以从您的Region List区域列表拖动一个Region区域的地方，您还可以录制来自外部声源的声音。

一个区域代表一个音频剪辑片段。例如，您的声音文件或者声音文件的某一部分。在下图中，被标记为“Audio 1” 和 “Audio 2”的水平条状区域就是音轨。在音轨Audio 1 内包含有音频信息（命名为“某某声音”）的矩形被成为一个区域。

什么是总线？

一条Bus总线类似于音轨，除了它不包含属于它自己的区区域。您不能直接录制到一条总线，也不能拖拽区域到总线里。在上面的图片中，被标记为“master”的就是一条总线。通常每个会话都有一个Master Bus主总线。从您的会话导出的所有音频都将被发送到主总线。

如何使用音轨和总线？

音频处理Plugins插件和Automation自动化都可以应用于音轨和总线。

音频轨道可以被路由到总线。事实上，许多音轨可以同时被路由到一条总线。总线通常被用作是将任何信号处理一次同时应用到许多音轨的简便方法。您可能会发现它有用，例如，路由所有包含鼓声的音轨到一个单独的、您将命名为“drum bus鼓声总线”的总线。然后，如果你决定你所有的鼓声音轨太大声，您可以快速调整“drum bus鼓声总线”的电平，而不是调整汇聚到一起的每个单独的音轨。

总线的另一个用处是可以拥有一个共用的Reverberation混响插件，因此任何需要Reverb混响效果的音频轨道都可以被路由到一个单独的总线。

添加音轨和总线

在任何现有的音轨和总线下方的空白区域右键点击，或者，点击菜单 Track音轨 > Add Track/Bus添加音轨/Bus总线（快捷键 Ctrl + Shift + N）。将会出现以下窗口：

Add添加允许您指定要创建多少音轨（或总线）。

在菜单中选择Audio Tracks音频轨道或者Busses总线以确定您要创建的是音轨或者总线。您也能选择创建一条MIDI Track音乐设备数字接口音轨或者一条Audio+MIDI Track音频+音乐设备数字接口音轨。Ardour提供的这三种音轨类型是取决于他们所包含的数据类型，而区分这三种音轨模式则是取决于他们的录制方式。本教程将仅介绍音频轨道和总线（全部音轨类型的详细介绍请参阅Ardour手册）。

您可以为所创建的音轨或总线随意起一个Name名称。Configuration配置下拉菜单允许您指定您希望新的音轨或总线可以处理有多少声道。例如，如果您将使用一个单独的麦克风录制您的声音到这个音轨上，可选择Mono单声道。如果您计划从现有的歌曲导入一个片段并放置到这个音轨上，可选择Stereo立体声。此处的选择也会影响到哪些插件可以使用在这音轨上（单声道音轨不能使用立体声插件，反之亦然）。

Track Mode音轨模式菜单能让您选择Normal普通，Non Layered不分层和Tape磁带。正常模式为每次录制创建一个新区域，建议初学者使用。在其他模式下的更多信息，请查看Ardour手册。关于乐器和分组选项的附加信息也可以在手册的其它页面找到。

Group分组选项允许您把新的音轨添加到现有的分组，或者在创建新的音轨时也创建一个新组。如果您是一个初学者，您现在还不必担心分组。仅供未来参考，您可以在Ardour手册找到更多的信息。

最后一个选项（Insert插入）允许您选择把新的音轨或总线放置在什么地方：起始点、结束点、已选中部分之前或之后。

最后，点击Add添加按钮创建您刚刚配置好的音轨或总线。您会看到它们作为新的一行出现在Main Canvas主版面上。

导入音频

（原文）

在Ardour里，音频的一部分被称为Regions区域。一个区域可以是整个声音文件或者是声音文件的一部分。在此您将学习到如何从您的电脑的硬盘导入音频文件，以便能在您的Ardour里使用它们。

要导入一个音频文件，首先在位于最右边的编辑器窗口的Region List区域列表上右键点击，如果您没有看到它，确保“View视图”菜单里已经勾选“Show Editor List显示编辑器列表”。一旦您看到编辑器列表，请注意这个地方显示的功能选项也会随着标签页的改变而改变。在您右键点击之前，确保区域标签页已经被选中。

一旦您右键点击了，会出现一个菜单，其中有Import to Region List导入到区域列表这个选项，点击这个选项。

现在您将会看到Add existing media添加已存在的媒体对话框（注意：打开到这个窗口的快捷方式是“Ctrl”+“I”)。在这个对话框的左边，您会看到一个文件浏览器，让您可以从硬盘里搜索您要添加的声音文件（初学者最好是从一个通用的文件格式开始，诸如WAV或AIFF)。在左下角有一个菜单，指明这些文件将被如何添加。“Add files as new tracks添加文件作为新的声轨”将导入音频文件并把它们放在一个新创建的声轨上。“Add files to region list添加文件到区域列表”将简单地把音频文件导入到该区域列表，不创建任何新的声轨。现在选择则个选项，因为在此我们不想让Ardour创建任何声轨。

• 提示：如果您在硬盘里没有任何合适的音频文件来跟着这些步骤做，可以点击“Search Freesound搜索自由声音”标签页（或访问freesound.org），从那里您可以找到大量的、遵循Public Domain and Creative Commons–licensed公用领域和知识共享协议许可的、具有各种不同的采样率和格式的声音样例。

在Add existing media添加已存在的媒体对话框的右边，您可以看到有一处选项，允许您检查您所选择的文件的属性。在这里您将看到文件名，声道的数量，采样率，声音文件的格式和长度，以及您选择添加到文件的任何标签说明。

Play播放按钮允许您使用试听总线来预览文件。最后，这个对话框提供有一个选项，能让您选择复制（多个）文件到当前会话的文件夹（Copy Files to Session复制文件到会话）。这是安全的，但是它会占用更多的硬盘空间。如果你不勾选这个选项，Ardour将使用硬盘上当前位置的这个声音文件。在这种情况下，如果文件被移动到硬盘上的一个新的位置，您可能会遇到麻烦，因为在下次您打开这个会话时Ardour无法找到它。在此强烈建议您勾选离开这个复选框（“Copy Files to Session复制文件到会话复制文件到会话”）。

单击OK确定继续。您所选择的（多个）文件将会成排出现在您的区域列表中。

• 提示：如果您选择的文件的采样率不匹配当前会话的采样率，Ardour会以红色显示不匹配的采样率。如果您试图导入这个文件，Ardour也会警告您采样率不匹配，并且询问您是否确认您无论如何都要嵌入。如果您选择嵌入这个有问题的文件，它不会以它所录制的采样率来回放，而是以当前Ardour会话的采样率来回放。这将导致声音以错误的速度和切换方式来播放。

一旦您已经经成功地在该区域列表里嵌入了您的音频文件，您就会在屏幕上看到它。在下面的截图中，三个文件已经被导入：“toaster_8”、“short-drone-mono”、“wheels-mono”。在“toaster_8”后面的数字[2]表明它是一个立体声文件。

通过拖拽并放置区域到主版面，您可以把它插入到一个现有的声轨里。

• 提示：当该区域的名字是用蓝色突出显示时，如果您点击中间的文字，Ardour会认为您正在试图重命名该区域（名字将变成可编辑状态）。为了从列表中点击并拖动一个突出显示的区域，您需要把鼠标刚好指向并点击在名字之前或之后。

释放按着的鼠标完成拖放操作。该区域将被插入在您放开它的那个准确的时间点。

Important: always make sure you are placing Stereo Regions on Stereo Tracks. If you drag a Stereo file onto a Mono Audio Track, only the left channel will used. In the screenshot below, a stereo file with very distinct left and right channels was dragged onto a Stereo Track and a Mono Track. Notice that in the Mono Track only the left channel is displayed (and played back).

Importing Audio Directly to a Track

As mentioned earlier, the Add existing media dialogue also allows you to import audio files directly onto tracks.

Choose Add files: as new tracks in order to automatically create a new track and add the selected file to it. The track will be named after the sound file name.

If you have previously selected on or more tracks, the menu will display the additional option Add files: to selected tracks in order to add a sound file into the already existing selected track.

Choose Insert Point

When using either one of the options above (“add as new track” or “add to selected tracks”), you should also specify where in the track you want the new Region to be placed. In the screenshot below, we are choosing “session start”.

The Region appears in a new track in the session. The new track automatically receives the name of the imported sound file.

The sound file will also appear in the Region List so that it can be inserted into other tracks as well (drag and drop).

Remove Regions from Tracks

To remove a region from a track, one can select it with the mouse and use the Cut function from the menu, the Control (or Apple) key and the X key, the Delete key or the key combination of fn and Backspace (which is used, for example, on a laptop keyboard that does not have a proper Delete key).

   TIP: Save your work often! The shortcut “Control” + “S” is your friend. Use it a lot, all the time.

录制音频

（原文）

Besides Importing Audio, another way to create Regions in your Ardour session is to record new audio.

The source of this audio could be the line or microphone inputs of your audio interface, or it could even be sound originating from other applications on your computer which have been connected to Ardour via JACK. Please see the section on Routing for more details.

This section will show you how to record audio from an external source (for example, a microphone) onto a track in Ardour.

First, you should check that the proper inputs have been routed to the track you wish to record to.

   Select the track by clicking on the empty space just below its name and volume slider.
   The Track becomes highlighted.
   The vertical strip Editor Mixer located on the left side of the Editor window should now show the Track you just selected (Audio 1 in the image above).
   Just below the Track name in the Editor Mixer you will find a button that allows you to edit the Routing.
   Click on that button to investigate the Routing.

   TIP: If you don’t see the Editor Mixer strip, use the shortcut “Ctrl” + “E” to make it appear.

In the next image you can see that the only input of this Mono Track is receiving signal from system capture_1. This normally means the first microphone input of your soundcard.

The tabs that you see displayed vertically on the left are available sources. “Audio 1 in” on the bottom right is the destination. The green dot represents a connection.

The Ardour tabs show the connections that can be made from other sources within Ardour. The Other tab displays audio connections available from software other than Ardour. The Hardware tab shows hardware connections (for example, the built-in microphone of your computer or the inputs from your sound card). In all cases, this Routing matrix communicates directly with JACK to change the Routing in the JACK system itself. This will be explained in more detail in the Understanding Routing chapter.

For the purpose of this chapter, simply make sure that system capture_1 (from Hardware tab) is connected to the Audio 1 track so that we can do a test recording. If you don’t see a green dot as in the screenshot above, click on the matrix to make the connection manually. You can now close this window.

   Note: the example above assumes you are recording a Mono sound source onto a Mono Track. If you want to record in Stereo, the instructions are pretty much the same, but you should create a Stereo Track. You should then see two green dots, one for capture_1 and another for capture_2.

Arming the Track

“Arming the Track” is simply to get it ready for recording. Once you have checked that the proper capture inputs have been routed to the Track, you can arm the Track to record by clicking on the small red icon on the horizontal track strip (not the big one in the Transport controls).

When properly armed, the small red icon will remain highlighted, and you will be able to see the incoming signal by looking at the Peak Meter on the Editor Mixer or on the horizontal Track strip.

   Note: unless you have told Ardour to do otherwise, the input being recorded will be monitored (in other words, heard) via the Audition output. If you are not using headphones to monitor the recording process, you may get some loud feedback at this point!

Arm Ardour and Start Recording

Now that you have armed the Track to record, you must arm Ardour itself to record by clicking on the big red button in the Transport menu. The button will blink in red, indicating that Ardour is ready to record. To start recording, click on the Play button in the Transport menu, or press the space bar of your computer keyboard. Clicking the Play button again (or pressing the space bar) will stop recording.

While recording, the armed Track will capture the sounds from the input. Any existing sound on other tracks will play normally during the recording. This allows you to play, sing or speak along with other Regions and Tracks you have already recorded or embedded in your Session.

While recording, you will be able to see the Levels (the amplitude in Decibels) of the incoming sound, as well as see the Peaks of the Waveform appearing as it is recorded.

Avoid Clipping

The audio in the screenshot below was recorded too loud and produced Clipping (in other words, the signal recorded was outside the bounds of what could be represented digitally), which results in a loss of information and audible distortion. The clipped peaks in the waveform are marked in red.

The best and easiest way to avoid Clipping is have some control over the volume of the incoming audio signal before it gets to the sound card. For example, you can can move the microphone further away from the sound being recorded or use a mixer to reduce the volume of the incoming signal.

When the audio signal has been recorded within proper limits, you should see no red Peaks, and the level meter should show a negative number as maximum peak (for example, a maximum peak of around −3.0 Decibels allows for a comfortable distance from the Clipping Point.)

The range of decibels between the region’s maximum Peak and the Clipping Point is commonly referred to as Headroom. It is common recording practice to keep approximately three to six Decibels of Headroom between the maximum of your signal and the Clipping Point, with the Clipping Point itself being represented as 0dB (zero Decibels). In other words, an audio region with a comfortable amount of Headroom would have its maximum Peaks between −6dB and −3dB.

Region List

Recorded audio appears as a new Region in the recording Track. Like all Regions, this newly recorded one will be available in the Region List, from where you can drag-and-drop it into other Tracks if needed.

The Region you just recorded will automatically receive the name of the Track where it was recorded, with different takes being automatically numbered. In the screenshot below, “Audio 1-1” and “Audio 1-2” represent two different recordings made on a track named “Audio 1”.

You might want to plan ahead and organize your recording Session by giving appropriate names to different tracks. For example, a Track used only for recording vocals can be named “Voice”. This way, recorded sound files will be named accordingly, and different takes will appear in the Regions List identified as “Voice-1”, “Voice-2”, etc, rather than the default generic names, such as “Audio 1”.

To rename a Track, just double-click on its name (before you arm the track to record) and type in the new name.

   TIP: Did we mention how important it is to save your work often? Hit “Control” + “S” right now. Get in the habit of hitting “Control” + “S” every few minutes.

Routing an audio signal is sending it from somewhere to somewhere else.

In addition to getting audio signals to and from Ardour, routing plays an important part inside Ardour itself. Examples of using routing inside Ardour include routing audio from Tracks to the Master Bus or to other Busses, creating ‘sends’, routing the outputs from Busses to the Master Bus, etc. (see chapter on Creating a Track for an explanation of Tracks and Busses). All routing, both internal and external to Ardour, is handled by JACK.

Routing in Ardour

The standard routing of inputs, tracks and busses in Ardour is determined when a new Session is created in the Advanced Options of the New Session dialog box (see Starting a Session chapter). By default, the routing is as follows:

   The audio device inputs are routed to the Track inputs.
   All outputs from Tracks and Busses are routed to the master bus inputs.
   The Master Bus outputs are routed to the audio device outputs.

Note that when a new Bus is created, nothing is routed to its input.

This routing setup makes sense for sessions containing only Tracks, but to make use of any Busses (other than the Master Bus) or to get creative with the paths of the audio signals inside Ardour, we need to be able to change the routing.

The Audio Connection Manager window (also known as the patchbay) is the main way to make connections to, from ,and within Ardour’s mixer. You can open this window with the shortcut “Alt” + “N”, or through the menu Window > Audio Connections.

The patchbay presents two groups of ports; one set of sources, and one of destinations. Sources and destinations are organized by tabs. The available sources are displayed vertically on the left side, and the destinations are displayed horizontally at the bottom.

In the screenshot below, notice that the “Hardware” tab is selected on the top left (that’s a source), and the “Ardour Tracks” is selected as a destination in the bottom. This means that the matrix you see displays connections from available hardware sound sources (for example, a microphone), into existing Ardour tracks.

The green dots represent a connection. The screenshot above tells us that incoming sounds from “system: capture_1” (the first input source of your soundcard, or the built-in microphone of your laptop) are going into Ardour track named “Audio 1”, and also that incoming sounds from “system: capture_1” and “system: capture_2” are respectively going into the Left and Right inputs of Ardour track named “Audio 2.”

Notice we can see that “Audio 1” is a Mono track because it only has one connection slot, while track “Audio 2” is Stereo since it has two slots (Left and Right).

The next screenshot shows the signal path from Ardour Tracks (selected vertical tab) into Ardour Busses (selected horizontal tab). As mentioned earlier, the default setting for all Ardour Tracks is that their sound goes to the Master Bus.

Note: remember that “Audio 1” is a Mono track? We saw it in the earlier screenshot that “Audio 1” only has one input slot. But now on the screenshot above you see that “Audio 1” has two outputs (Left and Right). This is normal: we define whether a track is Mono or Stereo by its number of inputs, not outputs. Mono tracks will hold a single channel of audio, but you can still choose to place the sound on the left or the right speaker (or anywhere in between). More on this in the chapter Panning.

Finally, let’s explore a couple more tabs in the Audio Connection Manager to see the sound going from the Master Bus to the actual hardware outputs (your loudspeakers or headphones):

As you can see, the selected source tab is now “Ardour Busses”, and the destination tab is “Hardware”. This session happens to have only one bus, the default “master out”. The green dots show that all sounds coming out of the Master Bus are going to system playback 1 and 2, which are the outputs of your soundcard.

How to connect and disconnect?

To make a connection, click on the desired empty square in the matrix; a green dot will appear to indicate the connection is made.

To undo a connection, simply click on an existing green dot and it will disappear.

Practical example of routing to a bus

In the following example session, there are two guitar Tracks and one unused Bus called Guitar Bus, all Stereo.

Suppose you want to send the output from the two guitar Tracks to the Guitar Bus instead of the Master Bus. This can be useful to control the volume of both guitars with just one Fader (in this case the Guitar Bus fader). Then the output of the Guitar Bus, which is the sum of the two guitars, goes directly to the Master Bus.

Here is how to edit the patchbay to get the desired routing. Select “Ardour Tracks” tab from Sources (vertical tabs), and “Ardour Busses” from destinations (horizontal bottom tabs). Undo existing connections from both Tracks to Master. Then create connections from both Tracks to Guitar Bus. The final result would look like this:

Now both guitar tracks are routed to the Guitar Bus, and no longer directly connected to the Master Bus. We then make sure that the Guitar Bus is, by its turn, routed to the Master Bus (the output routing of a Bus is edited in the same way as for a Track), so that we can still hear the sound from both guitar Tracks. Now we can control the volume of both guitar Tracks together by changing the Fader of the Guitar Bus. What’s more, we can now add Plugins to the Guitar Bus to process the sound of both guitar Tracks together.

Track- or Bus-specific views of the Patchbay

The Audio Connection Manager (Patchbay) that you open with “Alt” + “P” shows you the complete matrix of every single source and every single destination available in Ardour. Sometimes this is too much: you just want to quickly change the routing of a single track input or output, for example. Ardour allows you to access a relevant subset of Patchbay connections when you click directly on the Inputs or Outputs button of a Track or Bus in the Mixer Strip.

The Inputs button is at the top, and the Outputs button is on the bottom of the strip. Clicking on either one will show you a menu of connection options. In the screenshot below, for example, you would click on the “1/2” button right under the track name “Guitar-1” in order to access this menu:

You may select a connection right there from the menu, or choose “Routing Grid” to see a simpler version of the Audio Connection Manager with only the Inputs or Outputs of the selected Track or Bus.

All Ardour connections are JACK connections

It is important to realize that any routings that you make or disconnect from within Ardour are in fact JACK routings, which you can see from other applications like Qjackctl, Catia, or JackPilot, depending on your Operational System. Below is an example of a Catia window (Linux only) displaying the same JACK connections discussed above:

程序间路由

（原文）

Sometimes you may need to record the audio output of another program into Ardour (for example, the sound of a YouTube video playing in Firefox, or the output of SuperCollider or PureData). This chapter shows how to accomplish that.

The examples on this page were created on a computer running Ubuntu Linux. Beware that things may work differently if you are on another OS (in particular if you are using a Mac, in which case you will be using JackPilot). The general principles are always the same, though.

From your browser to Ardour

Web browsers (Firefox, Chromium, etc) are not JACK-aware applications. Luckily, systems such as KXStudio and UbuntuStudio come with a bridge application between regular system audio (like PulseAudio) and JACK. This tutorial assumes you are using a computer with this bridge already running and working.

The overall steps to record audio from YouTube (or any other sound coming from your browser) into Ardour are:

   Create a Stereo Track in Ardour
   Disconnect Hardware sources from Track inputs
   Connect PulseAudio Jack Sink to Track inputs
   Start recording into the Track
   Start playing the YouTube video

For this example, a new session was created with a new Stereo Track named “Firefox”:

Then we select the Track and click on the Inputs button on the Editor Mixer strip. In the screenshot above, it’s the button just below the track name (“Firefox”) in the Editor Mixer strip (it shows only a “-“ (dash)in the example above, meaning that there are no connections made yet). We are presented with the Patchbay window specific to that Track’s inputs.

First thing to do is to disconnect any microphone inputs from that track (“system capture”), if any. After disconnecting, this part of matrix for the “Firefox” Track should look like this (no green dots):

Next step is to change tabs in this same window. Choose “Other” as the source. This is where you will find other running applications that can be sound sources to Ardour. On a Linux computer with PulseAudio Jack bridge, you will see “PulseAudio JACK Sink” as a source. Click on the appropriate empty squares to create connections (green dots) between “front-left” and “front-right” to the Left and Right inputs of the “Firefox” Track. It should eventually look like this:

Now you are ready to go. Simply follow the same recording procedures explained in the Recording Audio chapter: record-enable (arm) the Track (small red circle on the track), arm Ardour to record (big red button; it starts blinking), then hit the Play button. Go back to your browser and start playing the YouTube video.

From JACK-aware applications to Ardour

Other music software like SuperCollider, Hydrogen, and PureData are JACK-aware. This means they will show up directly as source and destination options in Ardour’s Audio Connection Manager. You don’t need to worry about any PulseAudio / Jack bridge as in the YouTube example above.

The procedure is essentially the same: create a Mono or Stereo Track to record the audio, set that Track’s inputs to the desired source, and record as usual.

The screenshot above was taken while recording a drum pattern from Hydrogen directly into an Ardour track named “from Hydrogen”. Hydrogen’s window is on the right. Ardour’s Patchbay window was left open for demonstration: notice that the application “Hydrogen” shows up as a source under the “Other” tab. It is connected directly to the inputs of the track. Also notice that SuperCollider (another jack-aware application) happened to be open at the same time, though its window is not visible in this screenshot. SuperCollider provides 8 default sound outputs, all of which show up as potential sources in Ardour’s Patchbay.
