Virtual Audio Cable (VAC) is a software application that creates virtual audio devices to route audio streams between different applications on a Windows PC. Essentially, it acts as a virtual audio bridge or “cable” that transfers audio data from one program’s output directly to another program’s input without requiring physical audio hardware connections.
Key Features:
- Virtual Audio Devices:Â Creates one or more virtual audio input/output devices that appear as standard sound cards to the system.
- Audio Routing:Â Allows audio from any application to be sent to another application as if connected by a physical audio cable.
- Low Latency:Â Designed for real-time audio transfer with minimal delay.
- Multi-Channel Support:Â Supports multi-channel audio formats, including stereo and surround sound.
- Multiple Cables:Â Supports multiple virtual cables simultaneously for complex audio routing.
- Flexible Configuration:Â Users can configure sample rates, buffer sizes, and other parameters to optimize audio quality and performance.
- Use Cases:Â Audio recording, live streaming, podcasting, audio mixing, sound monitoring, audio processing with software effects, and more.
Typical Usage Scenarios:
- Streaming software capturing audio from games or media players.
- Routing microphone audio through processing software before sending to communication apps.
- Recording audio output from one application into another without loss of quality.
- Mixing audio streams from different sources virtually.
Virtual Audio Cable is widely used by audio professionals, streamers, and developers who need to manage and route audio digitally within their computer environment without relying on physical cables or sound hardware.
