I have a need for a portable device that amongst other things runs an e-ink screen with a web page as its outside in the sun for 8~12 hours per day. So a Pi can do this but I also need to run some sort of comms between 3 or 4 users. Hence looking for a "single board" solution and I found this.
a) Can I take 3 or 4 mic inputs and mix them to then go to all outputs (3 or 4 headphone sets?)
b) Can I run something like jack with this?
c) I really need some sort of noise cancelling software to temp take out any noise above a certain threshold (gunshots basically).
d) Possibly send the output across wifi / ethernet to a second pi where there would be second (or even a third pi) with another one of these (each).
From my initial reading I think I might be able to do this with multiple Pi's its the multiple mics and headphones that I am trying to get around.
