Virtual Audio Stream comes with four virtual stereo cables that help you quickly and easily reroute all audio output signals to selectable inputs. In order to record sound playback of any application, you will have to set one DDMF audio stream to act as the default playback device.

The recording application will then use this audio stream as the input and you will be able to rapidly record it without any fuss. You can even customize the connections and set the audio device type, active channels, sample rate, audio buffer size as well as the Midi output.
