JACK Audio Connection Kit is an open-source, low-latency audio server primarily used for professional audio routing and processing, suitable for advanced users. In contrast, Virtual Audio Cable is a commercial solution that simplifies audio routing between applications but may lack some of the flexibility and community support that JACK offers.
