How to create multiple instances of virtual sound cards using Virtual Audio Streaming?
Why we need multiple virtual sound cards?
By default, the setup program of Virtual Audio Streaming only installs one virtual sound card on targeted Windows. This is enough for most circumstances, however, some advanced users may need to use multiple virtual sound cards to create complex virtual audio channels.
For example, supposing you need to record Skype voice and redirect Internet radio to Audacity at the same time. Since one virtual sound card only contains one virtual cable, so the Skype Voice and Internet Radio will be mixed together in Virtual Audio Streaming. See below demo picture:
However, if you let Virtual Audio Streaming generate multiple virtual sound cards on Windows, you can use them independently to record Skype and Internet Radio separately. See below demo pictures:
