Cable — Virtual Audio

Virtual Audio Cable: Overview, Architecture, and Applications

Abstract
Virtual audio cable (VAC) technology creates software-based audio devices that route audio streams internally between applications without physical hardware. This paper reviews VAC concepts, architectures, implementation techniques, performance considerations, common use cases, and security/privacy issues, and concludes with recommendations for developers and users.

Virtual Audio Cable is a software program that creates a virtual audio device on your computer, which can be used to connect multiple audio applications, devices, and services. It allows you to redirect audio signals from one application to another, or from one device to another, without the need for physical cables or complex setup. Design and Implementation Recommendations

Because the loopback happens internally, the audio signal remains bit-perfect and avoids the quality loss or noise associated with digital-to-analog conversions in physical hardware. Top Use Cases The Ultimate Guide to Virtual Audio Cables: Routing
