The audio world has its own version of the IP debate, and if you’ve spent any time around broadcast engineers in the last few years, you’ll have heard it. MADI is old technology. AoIP is the future. Dante, Ravenna, AES67 - that’s where everything is heading, and anyone still specifying MADI is stuck in the past. I’ve heard this argument a lot. I’ve also spent years working with both technologies at major live events, and my view is considerably more nuanced. ...

For years I used a basic Excel spreadsheet to estimate bandwidth — it worked, but it was slow to update, hard to share, and far from elegant. So I built something better. RavennaCalc is a clean, browser‑based bandwidth calculator for Ravenna/AES67 streams. It’s open‑source, takes seconds to use, and gives reliable estimates without the spreadsheet overhead. ...
