|

// VCDevice is the device that appears as "Background Music" in programs that list the output
|
|
// devices, e.g. System Preferences. It receives the system's audio, processes it and sends it to
|
|
// VCApp by publishing an input stream. VCApp then plays the audio on the user's real output
|
|
// device.
