VBAN, The VB-Audio Network Protocol:

VBAN Protocol has been designed for real-time transport of digital audio stream in IP-based network environments. VBAN allows to send or / and receive audio to / from other computers of any local networks. Voicemeeter already allows easy way to manage several incoming / outgoing streams.

For Any Local Network Infrastructure:

Based on UDP Protocol, VBAN is made for Audio Pro and Audiophiles, to transport multichannel audio in native PCM format (all sampling rate supported). Developed like a “RADIO” transmitter / receptor system, the sender is always master and the receiver is always slave.
