VB-Audio CABLE is a Windows Audio Driver working as a Virtual Audio Cable. After installing the VB-CABLE driver, a new playback device appears in the audio device list and can be set as default device. VB-CABLE can be set as the default device, just like any regular audio device. The Configure and Properties buttons allow to setup multi-channel features and device sound quality. All signal coming in the CABLE input is going to the CABLE output. This makes it simple to record the audio stream using some other application.
VB-CABLE allows routing audio signals from one application to another. A typical application for the Virtual Audio Cable is to route your sound to an audio software in order to record and analyze it. From whatever audio source, to whatever audio software supporting MME, DirectX or WDM Audio Device drivers.
