A virtual media device is described for processing one or more input signals from one or more physical media input devices, to thereby generate an output signal for use by a consuming application module. The consuming application module interacts with the virtual media device as if it were a physical media input device. The virtual media device thereby frees the application module and its user from the burden of having to take specific account of the physical media input devices that are connected to a computing environment. The virtual media device can be coupled to one or more microphone devices, one or more video input devices, or a combination of audio and video input devices, etc. The virtual media device can apply any number of processing modules to generate the output signal, each performing a different respective operation.
