浏览器在我们的数字生活中扮演着重要的角色。如果您不知道，这些浏览器甚至允许您在当前选项卡上捕获或录制音频^{(record audio)}并将输出文件保存到您的计算机。但是，您需要为此安装Firefox 插件^{(Firefox add-on)}或Chrome 扩展程序^{(Chrome extension)}。

从浏览器选项卡录制或捕获音频

我们将看到如何使用这些扩展从Chrome和Firefox两种浏览器打开的当前选项卡中录制音频：^(Firefox)

1. Chrome 的 Chrome 音频捕获

2. Firefox 的实时记录器

让我们看看如何使用它们。

1] Chrome 的 Chrome 音频捕获

Chrome Audio Capture是Chrome浏览器的一个简单扩展，允许用户捕获在打开的选项卡（当前）上播放的任何音频。

安装此浏览器扩展程序后，您就可以开始捕获音频了。

您会在Chrome的工具栏上看到一个红色的记录图标。

^(Start)只需按“开始捕获”按钮，即可开始在选项卡上捕获所需的音频声音^{(Start Capture)}。

该扩展程序将开始从Chrome浏览器捕获音频。

如果您想录制多首歌曲，您只需在其他选项卡上重复这些操作，因为Chrome Audio Capture支持同时捕获多个选项卡。单击^(Click)Chrome 音频捕获^{(Chrome Audio Capture)}图标开始。

要停止捕获，请按“保存捕获^{(Save Capture)}”。停止捕获或达到时间限制后，将打开一个新选项卡供您保存和命名音频文件。确保^(Make)在关闭选项卡之前保存文件，否则文件将丢失！

如果您想了解扩展支持的不同输出文件格式，请转到选项^(Options)页面。在这里，您可以进行一些更改并保存设置。正如您在上图中看到的，目前，捕获可以保存为 .mp3 或 .wav 文件。用户还可以选择静音当前正在捕获的选项卡。

从其网上应用店为^{(Web Store)}Chrome下载它。

2] Firefox 的实时记录器

用于Firefox的Live Recorder插件将音频和视频实时录制为WebM。添加到Firefox后，工具栏下方会显示一个图标。

此外，如上图所示，开始录制的按钮将变为可见。

开始^(Start)录制，完成后，按“停止^(Stop)”按钮。

点击“预览^(Preview)”（带有相机的那个），一个新标签应该打开，寻求在您选择的程序中下载和播放文件的权限。

只需^(Simply)授予权限并开始播放录制的视频。

从这里^(here)为 Firefox 下载它。

That’s it!

Record audio from the browser tab of Chrome or Firefox

Browsers play an іmportant role in our digital life. If you are not aware, these brоwsеrs even allow you to сapture or record audio on the current tab and save the output file to your computer. However, you need to install a Firefox add-on or a Chrome extension for this purpose.

Record or capture audio from the browser tab

We’ll see how to record audio from the opened current tab of both browsers, Chrome and Firefox, using these extensions:

1. Chrome Audio Capture for Chrome

2. Live Recorder for Firefox

Let’s see how to use them.

1] Chrome Audio Capture for Chrome

Chrome Audio Capture is a simple extension for the Chrome browser that allows users to capture any audio playing on the opened tab (current).

Once you have installed this browser extension, you can start capturing audio.

You will see a red record icon appearing on the toolbar of your Chrome.

Start capturing the desired audio sound on a tab by simply pressing ‘Start Capture’ button.

The extension will start to capture audio from the Chrome browser.

If you would like to record multiple songs, you just need to repeat the actions on other tabs as Chrome Audio Capture supports multiple tabs that be captured simultaneously. Click on the Chrome Audio Capture icon to get started.

To stop the capture, press ‘Save Capture’. Once the capture is stopped or when the time limit is reached, a new tab will be opened for you to save and name your audio file. Make sure to save your file before closing the tab, otherwise, the file will be lost!

If you would like to find out different output file formats that the extension supports, go to the Options page. Here, you can make some changes and save the settings. As you can see in the image above, currently, the captures can be saved as either .mp3 or .wav files. Users also have the option to mute tabs that are currently being captured.

Download it for Chrome from its Web Store.

2] Live Recorder for Firefox

Live Recorder add-on for Firefox records audio and video as WebM, in real-time. After you add it to Firefox, an icon will be displayed under the tool bar.

Also, a button to start recording will become visible as shown in the image above.

Start recording and when done, press the ‘Stop‘ button.

Click on ‘Preview‘ (the one with the camera) and a new tab should open, seeking permission to download and play the file in a program of your choice.

Simply, grant the permission and start playing the recorded video.

Download it for Firefox from here.

That’s it!
