Next steps: Video streaming and production

I’ve done a lot of blogging on radio and Rivendell in particular. I’m a huge proponent of open tools and technologies wherever possible because it provides tons of flexibility, is cheap, and in many cases is just as powerful or easy to use as the commercial stuff. Radio and audio is complex, but why stop there?

But it’s not a simple drop-in tool for monitoring, sadly – we need to do a bit of work to make it so. Continue reading Interfacing SilentJack and Nagios

What we did was actually revolutionary in terms of the SU’s radio, and certainly isn’t something I’ve heard of another student station doing. The result was fantastic audio, a great sound overall, and a fun night. And near-zero latency. Here’s how it worked.
