> stream from its JACK input ports. Using this tool, an AC3 stream (up
> to 5.1 channels) is encoded in realtime and either written to a file
or
> streamed to standard output.

interface

> you can achieve full 5.1 surround mixing and monitoring of your JACK
> applications with a single digital cable, and no need for hardware
> supporting discrete inputs and outputs.
