Thanks for the great feedback. The device is a Behringer UMC 404HD which connects to a DAW (Digital Audio Workstation) software with a USB 2.0 Type B connection.
Such a setup permits one to play back multi-track music over (in this case) 4 speakers.
However, the source wav files for a 30 minute string quartet can be quite large. Instead of downloading, the concept is to have an Internet server (like Youtube) that could stream the output from such a device over the net, and on the other end to have a receptor device that outputs to USB that would be the local end of the client 404.
The end result would be streaming multi-track music over the Internet to multiple speakers, given a client receptor for the digital stream that be the output of the remote server.
Instead of diving into DAW I thought perhaps one could capture the data coming from the USB 2.0 at the server, send it streaming down the Internet, and reverse it there, into the client 404.
A USB Internet bridge.
