Virtual Network Audio Cables for Windows

You are in a small studio moving live feeds between Windows machines, and Virtual Network Audio Cables (VNAC) from TWasfy is designed for that purpose: transmitting and receiving high-quality audio over IP networks. It creates virtual system inputs and outputs and forwards microphones, interfaces, or system sounds across a local network with real-time transport. With support for professional AoIP modes, configurable sample rates, and diagnostic logging, it targets broadcasters, remote engineers, and multi-PC gamers needing reliable network audio routing.

You can keep audio on your LAN instead of routing through cloud services

When you need local control of feeds, the app sends audio directly between devices so no external account or cloud relay is required. That design reduces external dependencies for live broadcast booths and multi-room recording setups, because traffic remains on your local area network. The approach suits sessions where latency and privacy matter and you want per-route addressing within your subnet.

What audio codecs and network protocols does it actually handle?

If you care about codec choice and network compatibility, the app supports both uncompressed PCM and Opus compression and uses RTP-based transport. It operates over IPv4 and IPv6 and exposes SAP/SDP for session discovery, so you can integrate it with RTP-aware equipment. Those options let you pick denser compression for bandwidth-limited links or raw PCM when you prioritize fidelity.

How it manages synchronization and multi-destination routing

You need stable timing across machines, and the tool implements drift compensation plus automatic sample-rate synchronization to keep streams aligned. It also lets you create multiple simultaneous send and receive routes, each with its own IP address and port, enabling distinct feeds to different targets. Those capabilities matter when you split camera room microphones to a mixer and a recorder at once.

Is the interface tuned for engineers or casual users?

You see a dark, compact interface with local diagnostic logging rather than lengthy setup wizards. Configuration is focused and technical, which suits broadcasters and recording engineers who prefer control and traceable session logs. The app runs on Windows x64 systems and requires a LAN for device-to-device routing, so you should plan your network topology before connecting multiple endpoints.

A practical gateway for Windows-based local-network audio, with a focused scope

If you need predictable, per-route audio between Windows machines, the app is a practical gateway that keeps streams on your LAN and exposes detailed network controls. The trade-off is platform restriction to Windows x64 and a compact interface that assumes some networking familiarity. You should choose this tool if you value local routing and per-destination addressing over cloud-mediated convenience.
