Virtual Audio Cable 4.70

Virtual Audio Cable (VAC) is an audio bridge between applications that transmits sounds (audio streams) from app to app, from device to device.

VAC creates a set of virtual audio devices. Each device simulates an audio adapter (usually named a "card") whose output is internally connected to the input, making an audio loopback. If an application plays audio to the output of such device, the sound will not be audible because the signal is looped back to the input. But if another application records from the input, it receives the sound produced by the first app.

Such virtual devices are named Virtual Cables. The term "Virtual Cable" is used only in the description of VAC product, as a placeholder. Actual names of virtual audio devices/endpoints that you will see in applications' menus, are different (for example, "Line 1", "Line 2" etc.).

Each side of any Virtual Cable can be used by several audio apps at the same time. If two or more apps play sounds to the same playback endpoint, these sounds are mixed, and the result is transmitted to the recording side. It two or more apps record from the same endpoint, each app gets a copy of the sound.

Features
Offers up to 256 Virtual Cables. Each Virtual Cable is a one-way audio transport between applications, so you can transfer up to 256 independent audio signals between applications at the same time.
Less than 1 ms latency with the appropriate driver and application settings.
Almost any of fixed point PCM audio formats (1000..384000 samples per second, 8..32 bits per sample, 1..32 channels).
PCM format conversion (sampling rate, bits per sample, number of channels).
RT Audio (WaveRT) protocol support with notification events, packet mode, clock and position registers. Clock registers are bound to Virtual Cables so all streams in each cable are coherent.
Unlimited number of Kernel Streaming clients. You can share each Virtual Cable between any number of KS-aware audio applications or ASIO wrappers, at the same time with WASAPI Exclusive Mode connection.
Signal mixing from all render/playback streams in each Virtual Cable. You can mix signals from several applications in real time.
Signal volume control features (both attenuation and boost).
Channel scattering/gathering mode. Using KS-aware applications, you can remap particular channels in a stream.

Compatibility: VAC works in Windows XP, Vista, 7, 8, 8.1, 10 and 11.
