Why Worry About Your Air Chain?

Originally streamed February 8, 2024 

Reviewing AM and FM air chains in large and small markets, a plethora of problems can be found. Not only do these problems negatively impact audio quality, they affect Nielsen PPM encodability!

Inevitably, air chains degrade over time and for many reasons. Equipment, formats and other conditions change. Analog to digital conversions (or digital to analog) happen. “Stuff” that you might not even be aware of may have been added to the air chain over the years. 

But, if the air chain is working, why should I worry about it? This presentation discusses how to locate air chain problems and developing a course of action to resolve them and also covers air chain best practices as well as Processing 101.
