How To Pull Off A Live Broadcast Via Internet similar JK Audio Phone Coupler?

I'm in need of a little expertise...

Scenario: Client of radio station buys a block of airtime (15, 30, 60 minute weekly) for a live broadcast but wants to use the Internet to feed the radio station instead of using the stations JK Audio Dialup Auto Coupler, but cannot afford a broadcast codec ala Tieline/Comrex. Station would bring in the feed through Sonicwall Firewall/Router and then take the output of the receive unit and route it through a Broadcast Tools Switch. Station is automated so there would not be a human to "connect" the feed.

Is there anything out there that can accomplish this task? If so, what specific equipment is needed on the client side and station side?
 
FREE Windows Media Audio at client end. Ogg Vrobis mp3 encoder uses les bandwidth.

SLIGHT delay on any of these though. IT IS DIGITAl.

Station end would be Simian or another system that accepts a live stream or plain old computer fed to a broadcast tools switcher.
 
Thanks Chief but a follow up question...How would this be automated on the station side? If the client is running Windows Media Encoder then the station has to connect to it somehow right?

Is it possible that some device is out there that can push the feed from the client to the station and the station can automatically (station uses AudioVault) receive it with no human interaction?
 
my recommendation is a barix instreamer 100 at the remote location, exstreamer 100 at the studio end. Some networking experience required to set it up, but after that it is as close to a wire from one end to the other as you can get over the public internet. Delay should be 100-200ms.

Best situation for it work properly is to have a static ip on the sending end, the box at the station will then pull the stream from the remote location. I have tested dropping the network connection on both ends of such a link and it always connects right back up within a few seconds.
 
Free Zara Radio automation software can be set up to start and end broadcasts, and various internet streams and gives the station audio AGC, scheduled breaks etc. It might be all you need at the station end to pick up various internet streams, and run your broadcast. Zara is very reliable, uses few resources, and will run without problems on somewhat older, slower computers.

The Barix units are great also.
 
I wasn't sure about the barix because i've heard stories that it is best used if the stream is constant (24x7). I suppose its something to try.

Thanks for the Zara suggestion but station needs to be able to make this work using existing platform.
 
I agree with the Barix solution.

However, you could try Audio Compass loaded on both a studio and remote computer. The studio would be configured to listen on a specific port and the remote could connect and disconnect. The output of the studio computer would be wired as a feed on your BT switcher and AudioVault would switch the remote feed as necessary (seen as just another network feed). The program is bidirectional so you could configure a mix-minus feed to the remote for monitoring. Your delay with Audio Compass would be around 300ms.

I tried Audio Compass with mixed results: the audio was very good ("ISDN like"), but I had occassional audio drop-outs. In fairness, the problem *may* have been a networking issue. There is a 30 day free trial if you wish to try it out.

Good luck!
 
I have tried audiocompass, with bad results. worked fine over the LAN, outside the network it was way too unstable. YMMV.

The show we bring in with the barix boxes is 3 hrs per day, then the host just pulls the power from his instreamer. when he brings it back up it links right back up no problem at all.

As for the automation.. I only have experience with wireready and BT switchers. We run this show manually, seems it would be simple to automate just feeding the decoder into a switcher and telling the automation software when to switch to it.
