So it can be retrieved (recorded) by another (destination) application: All digital audio data sent (played) to the output endpoint by a “source” application, are implicitly transferred to the input endpoint. Inside each cable, these endpoints are connected to each other. Actual device/endpoint names that you will see in applications’ windows, are different.Įach Virtual Cable has a pair of audio endpoints: input (recording) and output (playback). The “Virtual Cable” term is used only in VAC description, as a placeholder. VAC simulates an audio adapter (card) and provides a set of virtual audio devices named Virtual Cables. With VAC, you can transmit sounds from any application to any other.

Windows audio application can produce (play back) and/or record sounds (audio signals) too.

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. VAC routes audio signals (streams) between such connected applications, keeping as low latency as possible. Virtual Audio Cable software (VAC), allows you to connect audio applications to each other. Yes, Virtual Audio Cable is safe to download and install on Windows 11, 10.
