Allows you to connect audio applications to each other.
Virtual Audio Cable software (VAC), allows you to connect audio applications to each other. VAC routes audio signals (streams) between such connected applications, keeping as low latency as possible. You definitely know that traditional hardware audio devices (CD/LP player, FM receiver, equalizer, amplifier etc.) may be connected together by electric (analog or digital) cables. Windows audio application can produce (play back) and/or record sounds (audio signals) too. With VAC, you can transmit sounds from any application to any other.
VAC simulates an audio adapter (card) and provides a set of virtual audio devices named Virtual Cables. The “Virtual Cable” term is used only in VAC description, as a placeholder. Actual device/endpoint names that you will see in applications’ windows, are different.
Each Virtual Cable has a pair of audio endpoints: input (recording) and output (playback). Inside each cable, these endpoints are connected to each other. All digital audio data sent (played) to the output endpoint by a “source” application, are implicitly transferred to the input endpoint. So it can be retrieved (recorded) by another (destination) application:
VAC delivers audio signals completely inside the computer. No audio hardware is required. There is no quality loss (if no format conversion and/or volume control are involved).
