VB-Audio Virtual Cable is the most popular free alternative—and many people use the terms almost interchangeably. It creates single virtual cables that route audio between applications, supports multi-client connections, and offers low-latency performance. Pricing is donationware (free with optional donations). While simpler than the original VAC (which supports more advanced features like multiple cables in its paid version), VB-Cable is excellent for basic routing needs.
VAC uses rather than polling. When the playback side writes enough data to fill a "packet" (configurable), the driver signals a kernel event. A user-mode service ( vac.exe ) or the capture application's thread then wakes up to read the data.
