How to exclude Audio (Voice-Com, Music, etc.) from your Stream/Recording?
Its fortunately quite easy to exclude an Audio source from your stream or recording. But there are a few things we cannot do. So let us take a look at the different sources we may have available:
- Voice-Communication (Teamspeak, Skype, etc.)
- Music/MediaPlayer (software with good Audio options: foobar, winamp, etc.)
- Game sound (with good Audio options)
- [External Inputs (Line-In, Digital-In are already excluded unless you add them)]
- Music/MediaPlayer (software with no Audio options: browser, itunes, etc.)
- Game sound (with no Audio options)
- Browser sound (Youtube, Flash stuff, etc.)
- Application sound (often no Audio options)
Music(no Audio options), Game(no Audio options), Browser(no Audio options) and Application(no Audio options) sounds CANNOT be split (or excluded) from each other, they will always use your default playback device. But you can exclude sounds of programs that allow you to select their Audio device. You simply need one Audio device that can be used in your recording/streaming tool while you have a second device that receives all sound from all sources. That way you could exclude sound from Teamspeak, or a Skype conversation from your Video, while still being able to talk with your friends or co-commentators.
Now I will show you two examples. On the left Virtual Audio Cable (VAC) is used as the default playback device, it will receive windows sound, game sound or whatever uses the default playback device in windows. The Speaker from Realtek will be selected in Skype or whichever software you want to exclude and that allows you to select the output device. Finally to hear the sound from VAC Line1 (game sound or windows sound) you can simply use the listen to feature and in the dropdown select the Speaker and of course activate listen to. In your recording software you either select Line1 as your desktop audio device or keep it on “default”, which will also be used if your software has no option to select a device.
On the right I used the option of splitting my front and back audio ports to get 2 seperate playback devices in Windows. In this case the Speaker is the only device that works with the Stereomix together. The Stereomix “copies” all input from the Speaker. It cannot copy sound from the Front Output or other ports of the soundcard. Thats why the Speaker has to be the default playback device. Select your Front Output in the software you want to exclude and use the Speaker in your Recording software. In the stereomix device you activate “listen to” and select your Front Output. You can of course also use a USB Headset or second soundcard instead of the Front Output. But your default device has to have a Stereomix.
