Abstract
A virtual signal source generating apparatus is provided. The virtual signal source generating apparatus includes at least an audio interface, a control module, a detecting module and a processing module. The control module is used for acquiring an audio signal from a signal source, wherein the audio signal includes a clock information and an audio information. The detecting module is used for detecting whether the audio interface is coupled to the signal source. The processing module is used for transmitting the audio signal. If the detecting module detects that the signal source disappears when the virtual signal source generating apparatus is in the recording mode, the control module transmits a control signal to the processing module so that the processing module transmits a virtual audio signal to a host.
