I have added Stereo Mix to my recording devices on my laptop running Windows 7 after I have installed the driver for my soundcard (the sound was working until then with the driver from Microsoft, but there was no Stereo Mix).

enter image description here

Trying to record Skype calls I found that some people recommend Stereo Mix in combination with Audacity.

The present question is more limited, (and in fact I do not want to know how to record Skype) I just want to know here a few things about this device:

  • What is it meant for? What is its main use?

I can record sounds that are played on the computer - and they are captured it looks like from the soundcard, as if by a virtual microphone. So, is this what Stereo Mix is meant as? A virtual microphone? Does it have settings of some kind? - can other inputs be added to it (similar to the aggregate device in Mac) so that, for example, when it is set as input device for an application, to capture both the "internal" sounds and the real mic?

"Stereo Mix" is the name given to the output stream (presented as a virtual audio device) after all channels have been combined.

It's a mix of all the channels, and is sometimes referred to (in the past anyway) as "What you hear".

There's usually very little/nothing you can configure about it because it's only job is to present the mixed channels. How much you can configure depends on what was included in the sound adapter driver you're using (as drivers are different, just like sound cards).

If you turn on a Mic's monitor in the recording devices panel (usually by unmuting it, or by enabling "Listen to this device" - again, depends on the driver being used), so that your voice comes out of the speakers, then it will be included in the Stereo Mix stream.

"Stereo Mix" allows you to make a recording of everything coming out of your computer's audio. So if you were listening to music on your headphones and you were talking into your mic at the same time, you could record both of those at once by utilizing "Stereo Mix".

In a recording application such as Audacity, you would set your source to be Stereo Mix instead of just your microphone.

What is Stereo Mix?

Stereo Mix allows you to record exactly what was being output to your speakers, without going through any analog/digital conversion. This feature is very handy for recording the audio off a website.

Stereo Mix is believed to take all the microphones and when you talk you will hear yourself back from the stereo mix.
