一些世界上最好的讲座、辩论和音乐在YouTube上免费提供。但是我们并不总是有时间观看视频，而通过手机数据流式传输音频会使我们破产。 

如果我们可以从YouTube 视频^{(YouTube video)}中提取音频不是很好吗？然后我们可以随时听它。

让我们解决从YouTube 上^(YouTube)翻录音频是否合法的问题。这取决于。假设一切都受版权保护。内容所有者^{(content owner)}可以将视频标记为知识共享^(Commons)、公共领域，或者只是在他们的描述中说任何人都可以使用它。 

但要完全确定，请联系内容所有者并请求许可。查看YouTube 的常见版权问题^{(YouTube’s frequently asked copyright questions)}。

对于我们从YouTube翻录音频的方法，我们将使用对Arthur Conan Doyle 爵士的采访^{(interview with Sir Arthur Conan Doyle)}。是的，福尔摩斯^{(Sherlock Holmes)}的创造者。 

我们将使用 VideoLan 的VLC 媒体播放器^{(VLC Media Player)}来执行此操作。它是一款出色的免费媒体播放器，适用于Windows、Mac OS X、iOS、Android和Linux。因此，如果您没有它，请立即下载并安装 VLC 媒体播放器^{(download and install VLC Media Player)}。

我们将使用的方法与使用VLC翻录YouTube视频非常相似。

• 转到YouTube并转到我们要处理的视频。从浏览器的地址栏中^{(location bar)}复制整个地址或 URL 。^{(address or URL)}

• 打开 VLC。在 Windows 上，转到Media > Open Network Stream。在 Mac 上，转到File > Open Network。

• ^(Enter)在网络URL 字段^{(URL field)}中输入YouTube 视频^{(YouTube video)}的URL。在Windows中，单击播放^(Play)。在 Mac 上，单击打开^(Open)。视频将开始播放。让它。

• 当视频仍在播放时，在Windows中转到Tools > Code Information。在 Mac 上单击Window > Media Information。

• 在打开的窗口底部，位置^{(Location )}字段中有一个长地址。复制并关闭该窗口。

• 停止视频。在 Windows 上，转到Media > Open Network Stream。在 Mac 上，转到File > Open Network。

• 将长地址粘贴到网络URL 字段中^{(URL field)}。单击^(Click)播放按钮^{(Play button and click)}旁边的向下箭头，然后单击转换^(Convert)。

• 在打开的窗口中，单击配置文件^(Profile)下拉菜单并选择^{(menu and select)} 音频 - MP3^{(Audio – MP3)}。如果我们想要的话，我们可以选择Audio – FLAC 或 Audio – CD 。^{(Audio – FLAC or Audio – CD)}

• 单击目标文件^{(Destination file: )}旁边的浏览^{(Browse )}按钮：字段，然后选择转换后MP3的保存位置。单击开始^(Start)。VLC将开始从YouTube 视频^{(YouTube video)}中提取音频并将其保存为MP3。 

音频翻录过程^{(ripping process)}将比播放视频快得多。这段视频的观看时间超过 10 分钟，但从YouTube 上^(YouTube)翻录音频只需要大约 2 分钟。

That’s It!

没有必要去一些充满令人毛骨悚然的广告的垃圾网站从YouTube 上^(YouTube)抓取音频。只需使用^{(Just use)} VLC。如果您以前没有使用过VLC，请了解有关它的更多信息。它不仅是一款出色的视频和音乐播放器^{(video and music player)}，您还可以执行诸如流式传输到 Chromecast^{(stream to Chromecast)}、修复倒置视频^{(fix upside-down videos)}以及从电影和节目中捕捉静止图像等操作。

How To Rip Audio From YouTube

Some оf the best lectures, debates, and music in the world is on YouTube for free. But we don’t always have the time to watch a video, and streaming audio ovеr cell data would bankrupt us. 

Wouldn’t it be great if we could just rip audio from a YouTube video? Then we could listen to it whenever we wanted.

Let’s address the issue of whether it’s legal or not to rip audio from YouTube. It depends. Just assume that everything is copyrighted. The content owner may mark the video as Creative Commons, public domain, or just say in their description that anyone can use it. 

But to be completely sure, contact the owner of the content and ask for permission. Review YouTube’s frequently asked copyright questions.

For our how-to on ripping audio from YouTube, we’re going to use an interview with Sir Arthur Conan Doyle. Yes, the creator of Sherlock Holmes. 

We’re going to use VideoLan’s VLC Media Player to do this. It’s a great free media player available for Windows, Mac OS X, iOS, Android, and Linux. So if you don’t have it, go download and install VLC Media Player now.

The method we’re going to use is very similar to using VLC to rip YouTube videos.

• Go to YouTube and go to the video we want to work with. Copy the entire address or URL from the location bar of the browser.

• Open VLC. On Windows, go to Media > Open Network Stream. On Mac go to File > Open Network.

• Enter the URL of the YouTube video in the network URL field. In Windows, click Play. On a Mac, click Open. The video will start to play. Let it.

• While the video is still playing, in Windows go to Tools > Code Information. On a Mac click on Window > Media Information.

• At the bottom of the window that opens, there’s a long address in the Location field. Copy that and close that window.

• Stop the video. On Windows, go to Media > Open Network Stream. On Mac go to File > Open Network.

• Paste the long address in the network URL field. Click on the down arrow next to the Play button and click on Convert.

• In the window that opens, click on the Profile drop-down menu and select Audio – MP3. We could choose Audio – FLAC or Audio – CD if that’s what we wanted.

• Click on the Browse button next to the Destination file: field and choose where to save the MP3 when it’s converted. Click Start. VLC will start ripping the audio from the YouTube video and saving it as an MP3. 

The audio ripping process will progress much quicker than if it were playing the video. This video is over 10 minutes long to watch but only took about 2 minutes to rip the audio from YouTube.

That’s It!

There is no need to go to some spammy website full of creepy ads to rip audio from YouTube. Just use VLC. If you haven’t used VLC before, learn more about it. Not only is it a great video and music player, but you can do things like stream to Chromecast, fix upside-down videos, and capture still images from movies and shows.
