当您合并音频文件时，您正在合并它们，因此多个文件将作为一个音频文件存在。您可以使用在线音频加入站点和离线音频合并软件程序。
如果您正在制作播放列表，并且希望它们一首接着一首地播放而没有任何停顿，您可能想要合并两首或多首歌曲。这在一些YouTube专辑中很常见，创作者会将所有歌曲上传到一个视频中。
合并声音文件的另一个原因是如果您录制了语音备忘录或画外音，但有很多umms和其他不必要的部分。您可以删除这些部分，然后将其他剪辑合并在一起以制作一个连续文件。
下面详细介绍了几种合并MP3(MP3s)和其他音频文件的方法。您可以选择您认为最适合您的情况的任何方法。
提示(Tip)：如果您的音频文件需要采用不同的格式才能与以下任何这些网站或程序一起使用，或者如果您希望导出的文件以其他一些音频文件格式存在，则有免费的方法可以将您的音频转换为不同的格式(free ways to convert your audio to a different format)。

使用 Audacity 剪辑和合并音频(Clip & Merge Audio With Audacity)
如果简单的上传和合并不是您想要的，因为您需要在合并之前编辑歌曲或录音，那么Audacity就是您想要的。它可以让您消除背景噪音(remove background noise)，为歌曲添加效果，并轻松地将多个文件连接在一起以制作长录音/歌曲。
以下是有关如何使用Audacity剪辑和合并音频文件的简要说明：
- 使用“文件(File )” > “打开(Open)”菜单导入要修剪的音频文件。
- 加载后，单击并拖动歌曲的任何区域以突出显示要删除的内容，然后按Delete
键。
- 随意(Feel)放大您需要的距离，以找到您想要剪掉的确切部分。

使用 Windows 命令提示符合并文件(Use The Windows Command Prompt To Merge Files)
除非您喜欢使用Command Prompt(Command Prompt) ，否则这不应该是您的第一选择，但是您无需下载任何程序或打开歌曲加入网站就可以做到这一点仍然很整洁。
这种合并文件的方法的一个缺点是您必须在命令提示符(Command Prompt)中输入每首歌曲的名称，或者至少重命名您的歌曲以使其更易于输入。
- 打开命令提示符(Open Command Prompt)。
- 将目录更改为音频文件所在的位置。这是一个例子：
cd C:\Users\Matt\Downloads
输入此命令，其中每个文件名对应于您正在处理的文件：
copy /b file.mp3 + file2.mp3 + file3.mp3 + otherfile.mp3 finalmerge.mp3
请注意(Notice)，我们在示例中合并了四首歌曲。最后一部分，称为finalmerge.mp3，是我们选择作为新文件的名称。所有其他实例都是我们要合并的文件的名称。
合并音频文件的提示(Tips On Merging Audio Files)
如果您需要使用视频中的音频，您可以很容易地从中提取声音。只要(Just)确保你这样做没有侵犯任何版权。
大多数歌曲在最后都有一点沉默。如果您希望合并的歌曲无缝播放，请消除Audacity或上述其他音频编辑器中的这些空白。只需(Just)根据需要多次播放歌曲，这样您就可以确定在导出音频之前，没有任何不需要的静音空间。
关于这一点，如果您想要(want)歌曲之间的静音区域但它们尚不存在，那么Audacity是制作这些区域的好方法。在录音中的任何位置使用“生成(Generate )” > “静音(Silence)”菜单项来添加您选择的任何长度的空格。
How To Merge Multiple Audio Files Into One
When you mergе audio files,
yoυ’re combining them so multiрle files will exist as a single aυdio file.
There аre both online audio joining sites and offline audio merging software
рrograms you can use.
You might want to merge two
or more songs if you’re making a playlist and you want them to play one after
the other without any pauses. This is common with some YouTube albums where the
creator will upload all the songs merged into one video.
Another reason to merge
sound files is if you’ve recorded voice memos or a voiceover, but there are
lots of umms and other unnecessary
parts. You can delete those sections and then merge the other clips together to
make a continuous file.
Detailed below are several
ways to merge MP3s and other audio files. You can pick whichever method you
think would work best for your situation.
Tip: If your audio files need to be in a different format to work with any of these websites or programs below, or if you want the exported file to exist in some other audio file format, there are free ways to convert your audio to a different format.
How To Merge Audio Files Online
Audio Joiner is a website dedicated to merging audio files online. This means you don’t have to download anything to make it work. Just upload the tracks you want combined and then download the single file when you’re done.
Here are some of its
notable features:
- Supports
fade in and fade out.
- You can
clip out a section to use from each file.
- Lets you
reorder the files.
- Choose the
specific second in the file to start and end it.
- Export the
merged file to MP3, M4A, WAV, or FLAC.
- Download
the file to your computer or Google Drive or Dropbox account.
Clideo’s Audio Joiner is a lot like the other online song joiner above, but this one has a few extra features you might prefer. Plus, the way the site is designed makes it feel easier to just throw up a few songs and merge them without doing any editing, which might be what you’re after.
- Open files
from a URL, your computer, Dropbox, or Google Drive.
- Export to
the same format as the songs or save the merged audio file to AAC, AC3, AIFF,
APE, CAF, FLAC, or M4A.
- Save the
file to your computer or pick your Google Drive or Dropbox account.
If these two options aren’t what you’re looking for in an online MP3 merger, try Audio Editor or Ofoct.
Clip & Merge Audio With Audacity
If a simple upload-and-merge isn’t what you’re after because you need to edit the songs or recordings before merging them, Audacity is what you want. It lets you remove background noise, add effects to the songs, and easily join multiple files together to make a long recording/song.
Here’s a quick rundown on
how to use Audacity to clip and merge audio files:
- Use the File > Open menu to import the audio file you want to trim up.
- Once it’s
loaded, click-and-drag over any area of the song to highlight what you want to
delete, and then press the Delete
key.
- Feel free
to zoom up as close as you need to, to find the exact parts you want to clip
out.
- Repeat
steps one and two to edit the other audio file you want merged with this one.
- Select all
of the second one, copy it, and then return to the window of the first one you
edited.
- Go to the
beginning or end (wherever you want the other audio file placed) and use the Edit > Paste menu item to put the copied clip next to the other one.
- Repeat
these steps as many times as you need to so that all the files are edited and
merged just how you want.
- Go to File > Export to pick an audio file format to save the merged file to.
Your options include MP3, WAV, OGG, FLAC, M4A, WMA, and a few others.

Use The Windows Command Prompt To Merge Files
This shouldn’t be your
first option unless you like messing around with Command Prompt, but it’s still
neat that you can do this without downloading any programs or opening a song
joiner website.
One downside to this method
for merging files is that you have to type each song name into Command Prompt,
or at least rename your songs to make them easier to type.
cd C:\Users\Matt\Downloads
Enter this command, where every file name corresponds to the files you’re dealing with:
copy /b file.mp3 + file2.mp3 + file3.mp3 + otherfile.mp3 finalmerge.mp3
Notice that we’re merging
four songs in our example. The very last part, called finalmerge.mp3, is the name we’ve chosen as the new file. All the
other instances are the names of the files we’re merging.
Tips On Merging Audio Files
If you need to use the audio from a video, you can extract the sound from it pretty easily. Just make sure you aren’t violating any copyrights doing so.
Most songs have a little
bit of silence at the very end. If you want your merged songs to play
seamlessly, remove those gaps in Audacity or the other audio editors mentioned
above. Just play the song over as many times as you need to so that you know
for sure that before you export the audio, there aren’t any unwanted silent
spaces.
On that note, if you want areas of silence between your songs
but they don’t already exist, Audacity is a great way to make those. Use the Generate > Silence menu item anywhere within the recording to add empty spaces
of any length you choose.
