Windows Movie Maker非常易于使用，在为您的视频和照片幻灯片添加背景音乐时，该主题保持不变。(background music)Windows Movie Maker的音频编辑(audio editing)功能非常基本，主要限于淡入淡出、更改音频的起点和终点(start and end points)以及调整整个剪辑的音量。但是，如果您只想为家庭电影(home movie)添加一点情调音乐(mood music)，那么Windows Movie Maker可以让您从自己的音乐收藏(music collection)中添加配乐。在本教程中，我们将向您展示如何将音乐添加到您的Windows Movie Maker项目以及如何编辑音频剪辑。
如何将音乐(Music)添加到Windows Movie Maker 项目(A Windows Movie Maker Project)
将照片或视频剪辑添加到Windows Movie Maker时间线后，您就可以开始添加音乐以在其后面播放。最简单的方法是单击或点击功能区“主页”选项卡中的“(Home)添加音乐(Add music)”按钮。此按钮位于“添加(Add)”部分。
从那里您可以浏览到任何兼容的音频文件并将(audio file and import)其导入您的时间线。支持的文件类型包括：.WMA、.MP3、.WAV、.M4A、.AIFF 和.AIF(.AIFF and.AIF)。
默认情况下，当您添加歌曲时，它将被放置在时间线的开头。
如何在时间线上移动声音
如果您想在时间线的其他位置添加音乐，您可以单击添加音乐(Add Music)按钮的文本而不是图标。现在选择在当前点添加音乐(Add music at the current point)选项。
音频剪辑(audio clip)将从当前播放头位置放置。
或者，您可以单击并拖动音频剪辑(audio clip)以沿时间线重新定位它。
如何在Windows Movie Maker中编辑(Windows Movie Maker)声音(Sounds)
音乐工具(Music Tools)下功能区上的选项选项(Options)卡可让您访问有限范围的音频编辑工具。为了显示Music Tools Options，您必须选择一个音乐剪辑(music clip)或将播放头放置在时间线上有音乐的某个点上。
在功能区的音乐工具选项选项(Music Tools Options)卡中，您有以下工具：
音乐音量：(Music Volume:)使用可用滑块调整整个剪辑的音量。
Fade In/Fade out:允许您在剪辑的开头或结尾(beginning or end)以三种速度淡入或淡出：慢、中或快(medium or fast)。
拆分：(Split:)将选定的音频片段(audio clip)拆分为播放头当前位置的两个片段。
设置开始时间：(Set start time:)将音频剪辑的开头移动到时间轴上播放头的位置，或在右侧字段中输入的时间。不改变剪辑本身。
设置开始点：(Set start point:)这会更改歌曲中剪辑开始播放的点。例如，如果您想跳过歌曲中 30 秒的前奏或几秒钟的静默，您可以更改起点(start point)。您可以在音频中您希望剪辑开始的位置暂停播放，也可以手动输入开始点。(start point)与Set start time不同，这不会更改剪辑的位置。在下图中的示例中，声音从第 10 秒开始，但同时出现在时间线中。
设置终点：(Set end point:)设置剪辑的终点。如果您选择了淡出，这是剪辑将完全淡出的点。
限制
不幸的是，这是Windows Movie Maker 的(Windows Movie Maker's) 音频编辑(audio editing)功能的全部范围。虽然您可以播放音乐剪辑和音频（即包含在视频文件(video file)本身中的音频），但您不能将两个音轨叠加在一起。
此外，在Windows Movie Maker(Windows Movie Maker)中无法录制旁白- 您必须在另一个程序中录制您的配音，然后将其导入，就像您录制音乐一样。但是，鉴于一次只能播放一个音轨，这意味着您将无法将音乐放在旁白后面，除非您首先导出完全“混合”版本的Windows Movie Maker项目，其中只有视频和音乐(video and music)，然后使用您制作和保存的剪辑创建一个新的Windows Movie Maker项目。(Windows Movie Maker)
此外，您不会在音频剪辑的任意点获得平滑淡入淡出的音量平移。(volume pan)相反，如果您想为旁白腾出空间，则必须拆分剪辑并让它们完全淡出或淡入。
结论
总体而言， Windows Movie Maker( Windows Movie Maker)有很多不足之处，包括以前版本的Windows Movie Maker中未包含的一些功能。但同样，Windows Movie Maker的宗旨就是易于使用。这是关于在几分钟内将您的照片和视频制作成具有专业外观的幻灯片或家庭电影。如果您对此工具有任何疑问或问题，请随时使用下面的评论表。
How To Add Music To Videos In Windows Movie Maker
Windows Movie Maker is all about ease of use and when it comes to adding background music to your videos and photo slideshows, that theme remains the same. Windows Movie Maker's audio editing features are very basic and mostly limited to fading in and fading out, changing the start and end points for the audio and adjusting the volume for the entire clip. But if all you want is a little mood music for your home movie, then Windows Movie Maker lets you add a soundtrack from your own music collection. In this tutorial, we'll show you how to add music to your Windows Movie Maker project and how to edit audio clips.
How To Add Music To A Windows Movie Maker Project
Once you have photos or video clips added to your Windows Movie Maker timeline, you can begin adding music to play behind it. The easiest way to do this is to click or tap the Add music button in the Home tab on ribbon.This button is found in the Add section.
From there you can browse to any compatible audio file and import it into your timeline. Supported file types include:.WMA,.MP3,.WAV,.M4A,.AIFF and.AIF.
By default, when you add a song, it will be placed at the beginning of the timeline.
How To Move Sounds On The Timeline
If you'd like to add music elsewhere in the timeline, you can click the text of the Add Music button rather than the icon. Now select the Add music at the current point option.
The audio clip will be placed from the current playhead position.
Alternately, you can click and drag the audio clip to reposition it along the timeline.
How To Edit Sounds In Windows Movie Maker
The Options tab on the ribbon, under Music Tools, gives you access to a limited range of audio editing tools. In order to reveal the Music Tools Options, you must have a music clip selected or have the playhead positioned at a point along the timeline that has music.
In the Music Tools Options tab on the ribbon, you have the following tools:
Music Volume: Adjust the volume of the entire clip, using the available slider.
Fade In/Fade out: Allows you to fade in or fade out at the beginning or end of the clip at three speeds: slow, medium or fast.
Split: Splits the selected audio clip into two clips at the current position of the playhead.
Set start time: Moves the beginning of the audio clip to the position of the playhead on the timeline, or at the time entered into the field on the right. Does not alter the clip itself.
Set start point: This changes the point within the song at which the clip begins playing. For example, if you want to skip through a 30-second intro or a few seconds of silence in a song, you could change the start point. You can either pause playback at the point in the audio where you want the clip to begin or type in the start point manually. Unlike Set start time, this does not change the position of the clip. In the example from the picture below, the sound begins from the 10th second, but occurs at the same time in the timeline.
Set end point: This sets the endpoint of the clip. If you've selected a fade out, this is the point where the clip will be completely faded out.
Limitations
Unfortunately, this is the full extent of Windows Movie Maker's audio editing features. While you can have music clips and audio playing back (i.e. audio that is included in the video file itself), you can not include two audio tracks on top of each other.
Also, there's no ability to record narration in Windows Movie Maker - you'll have to record your voice over in another program and then import it, just like you would music. However, given the limitation of one audio track at a time, this means that you won't be able to put music behind your narration, unless you first export a completely "mixed down" version of your Windows Movie Maker project with only video and music and then create a new Windows Movie Maker project using your produced and saved clip.
Furthermore, you don't get a volume pan for smooth fading in and out at arbitrary points in the audio clip. Instead, you have to split clips and have them fade out or fade in completely, if you want to carve out a space for narration.
Conclusion
Overall, there's a lot to be desired in Windows Movie Maker - including some features that were not included from the previous versions of Windows Movie Maker. But again, Windows Movie Maker is all about ease of use. It's about getting your photos and videos into professional looking slide shows or home movies within minutes.
