Barix Boxes are IP audio encoders/steamers for transporting radio station audio, and this report tells of several instances where Barix Boxes were hacked and used to transmit unwanted material. BARIX HACK |

Yes, I read about this hack in my Radio World magazine just the other day.
I have three different STL methods which use AOIP. The first I used was in fact the Barix boxes. Great if you have a wired network connection. Our high school studio has these also but has not employed them yet. I can't use the Barix for live remotes partly due to the need for a wired network connection. The other reason is it's cumbersome to route the stream as the remote network would have to open ports through their firewall. Generally, that's not going to happen without lots of pre-planning.
Then there's good 'ole TeamSpeak. That has been the work horse for all of our live remotes so far. As a software based STL it runs on a laptop and uses WIFI to connect to the internet. Using a VPN, it can connect to the transmitter site through the firewall. TeamSpeak has been very reliable as an STL with only very minor audio drops.
Last week I moved our "live" studio into our office. Previously the programming ran at the transmitter site. As there will be a live show starting May 1st, it makes it easier to run the whole show from the office. Rather than use TeamSpeak which relies on the internet to reach the TeamSpeak server at my house, I wanted a way to stream with lowest latency on our local area network. Much less problematic than using the internet.
This brought about my latest venture into AOIP STL using software from VBAN. I stumbled onto this while looking for a substitute for my demo version of Virtual Cable which generates an annoying audio water mark every 10 seconds. The VBAN software is freely downloaded and fully functional. They request a donation and I may actually cough up some bucks for this package.
They offer three different "consoles". One is receive only. One is a multi-bus mixer with receive and send streaming. One is a more involved mixer, streaming receiver and sender as well as a recorder/player of audio files. With that you can record your mixed audio as well as play it back.
VBAN has been streaming my programming for several days with no hiccups or crashes. It doesn't seem to load down the processor and has useful features and a nice GUI interface.
Hopefully as I'm behind a fairly secure network firewall it should not be hacked.
