立体声混音没有声音

You don’t have to hold up a microphone to your computer’s speakers to record its audio. Even if you don’t have a Stereo Mix option on your PC, you can easily record the sound coming from any Windows PC.

您不必举着麦克风连接计算机的扬声器来录制其音频。 即使您的PC上没有立体声混音选项，也可以轻松记录来自任何Windows PC的声音。

You can record the sound coming from your PC in numerous ways, and we’re going to show you the three best we’ve found. The first two options use only software, and the third relies on an old trick that connects your computer’s audio output to its audio input with an audio cable.

您可以用多种方式记录来自PC的声音，我们将向您展示我们发现的三种最佳声音。 前两个选项仅使用软件，而第三个选项则依靠一个古老的技巧，即通过音频电缆将计算机的音频输出连接到其音频输入。

选项1：立体声混音 (Option 1: Stereo Mix)

Stereo Mix is sometimes called “What U Hear.” It’s a special recording option that your sound drivers might provide. If it is included with your drivers, you can select Stereo Mix (instead of a microphone or audio line-in input), and then force any application to record the same sound that your computer is outputting from its speakers or headphones.

立体声混音有时被称为“您听到了什么”。 您的声音驱动程序可能会提供一个特殊的录音选项。 如果驱动程序附带了它，则可以选择“立体声混音”(而不是麦克风或音频输入输入)，然后强制任何应用程序录制与计算机从扬声器或耳机输出的声音相同的声音。

On modern versions of Windows, Stereo Mix is generally disabled by default—even if your sound drivers support it. Follow our instructions to enable the Stereo Mix audio source on Windows. After enabling Stereo Mix, you can use any audio-recording program, and just select “Stereo Mix” as the input device instead of the usual “line-in” or “microphone” option.

在Windows的现代版本中，立体声混音通常默认情况下处于禁用状态，即使您的声音驱动程序支持它也是如此。 请按照我们的说明在Windows上启用Stereo Mix音频源。 启用立体声混音后，您可以使用任何音频录制程序，只需选择“立体声混音”作为输入设备，而不是通常的“线路输入”或“麦克风”选项。

On some devices, you may not have this option at all. There may be a way to enable it with different audio drivers, but not every piece of sound hardware supports Stereo Mix. It’s unfortunately become less and less common.

在某些设备上，您可能根本没有此选项。 可能有一种方法可以使用不同的音频驱动程序来启用它，但是并非每个声音硬件都支持立体声混音。 不幸的是，它变得越来越普遍。

选项2：Audacity的WASAPI环回 (Option 2: Audacity’s WASAPI Loopback)

Don’t have a Stereo Mix option? No problem. Audacity has a useful feature that can record the audio coming out of your computer—even without Stereo Mix. In fact, Audacity’s feature may be even better than Stereo Mix, assuming you’re willing to use Audacity to record the audio. This method takes advantage of a feature that Microsoft added in Windows Vista named the Windows Audio Session API (WASAPI). The feature also functions in Windows 7, 8, and 10, and helps make up for the lack of a Stereo Mix option on modern Windows PCs.

没有立体声混音选项？ 没问题。 Audacity具有一项有用的功能，即使没有立体声混音，也可以录制从计算机发出的音频。 实际上，假设您愿意使用Audacity录制音频，Audacity的功能甚至可能比立体声混音更好。 此方法利用了Microsoft在Windows Vista中添加的名为Windows Audio Session API(WASAPI)的功能。 该功能还可以在Windows 7、8和10中使用，并有助于弥补现代Windows PC上缺少“立体声混合”选项的麻烦。

In Audacity, choose the “Windows WASAPI” audio host, and then choose an appropriate loopback device, such as “Speakers (loopback)” or “Headphones (loopback).”

在Audacity中，选择“ Windows WASAPI”音频主机，然后选择适当的回送设备，例如“扬声器(回送)”或“耳机(回送)”。

Click the Record button to start recording the audio in Audacity, and then click Stop when you’re done. Because you’re using Audacity, you can easily trim and edit the sound file when you’re done.

单击“录制”按钮开始以Audacity录制音频，然后在完成后单击“停止”。 由于您使用的是Audacity，因此您可以在完成后轻松修剪和编辑声音文件。

Update: If this doesn’t work, you may also need to select the correct number of recording channels to match your device using the dropdown box to the right of device selection box. For example, If you have a 7.1 channel headset, select “8.”

更新：如果此操作不起作用，则可能还需要使用设备选择框右侧的下拉框，选择正确数量的记录通道以匹配您的设备。 例如，如果您有7.1声道耳机，请选择“ 8”。

Audacity’s tutorial website explains why this feature is actually better than Stereo Mix:

Audacity的教程网站解释了为什么此功能实际上比Stereo Mix更好：

“WASAPI loopback has an advantage over stereo mix or similar inputs provided by the soundcard that the capture is entirely digital (rather than converting to analog for playback, then back to digital when Audacity receives it). System sounds playing through the device selected for WASAPI loopback are still captured, however.”

“ WASAPI环回具有优于立体声混音或声卡提供的类似输入的优势，即捕获完全是数字的(而不是转换为模拟以进行回放，然后在Audacity接收到它时又恢复为数字)。 但是，仍会捕获通过为WASAPI环回选择的设备播放的系统声音。”

In other words, your recorded sound file will be higher-quality when using Audacity’s WASAPI loopback option.

换句话说，使用Audacity的WASAPI环回选项时，录制的声音文件将具有更高的质量。

选项3：音频线 (Option 3: An Audio Cable)

If neither of the first two options suit your needs, there’s always the low-tech solution—although it’s a bit of a hack. Just get an audio cable with a male 3.5mm connector on both ends. Plug one end into the line-out (or headphone) jack on your PC, and the other end into the line-in (or microphone) jack. You’ll stop hearing the sound your computer produces, but you can use any audio-recording program to record the “line in” or “microphone” input. To actually hear the sound, you could get a splitter, and then output the audio to headphones or speakers at the same time you direct it back into your computer.

如果前两个选项都不满足您的需求，那么总会有低技术含量的解决方案-尽管这有点麻烦。 仅需获得两端带有3.5mm公连接器的音频线即可。 将一端插入PC上的线路输出(或耳机)插Kong，另一端插入线路输入(或麦克风)插Kong。 您将不再听到计算机发出的声音，但是您可以使用任何音频录制程序来录制“线路输入”或“麦克风”输入。 要实际听到声音，您可以使用分配器，然后在将音频直接导回计算机时将其输出到耳机或扬声器。

Sure, this is inconvenient and silly compared to to the first two software-only options we talked about. But, if you desperately need to capture the audio coming out of your computer in an application that isn’t Audacity and you don’t have Stereo Mix, the cable trick allows you to do this.

当然，与我们谈论的前两个纯软件选项相比，这是不便且愚蠢的。 但是，如果您迫切需要在非Audacity的应用程序中捕获计算机中发出的音频，并且没有立体声混音，则可以使用电缆技巧来完成此操作。

Obviously, copyright laws may prevent you from distributing whatever recordings you make in this way, so don’t use these tricks for piracy! After all, even if you were going to pirate some audio, there’d be easier ways to do it than this.

显然，版权法可能会阻止您以这种方式分发您制作的任何唱片，因此请不要使用这些技巧进行盗版！ 毕竟，即使您要盗版某些音频，也有比这更简单的方法。
