Radio Terminology (Jargon) Guide
Radio Terminology (Jargon) Guide
by on 27.09.2011

In this article Radio terminology is explained.  There are so many terms and much jargon in the radio industry.  When I first started out in radio I was bombarded by words which I didn’t understand.  I just nodded and tried to work out what the hell my colleagues were talking about.   So to save you the embarrassment of not knowing or looking like a rabbit in the headlights when someone mentions “clean-feed” here are a list of radio terminology used in radio and production.  A lot of words mean the same thing, you’ll also find that some words and terms mean different things to different people, especially between commercial radio and the BBC.  Thanks to those who have sent me their suggestions of radio terminology for this glossary. If you think there’s anything missing or a word means something different to you please let me know via the contact page or submit a comment below. Let’s get jargon-busting!

Radio terminology explained
