A radio sweeper is a short, pre-recorded sample used by radio stations as segues between songs that give listeners a brief station identifier or promo, generally 20 seconds or less: "You're listening to the soft sounds of radio. Easy listening throughout the Bay Area," for example.
Dry radio sweepers are voice only—no music or sound effects—whereas wet sweepers generally contain sound FX (also known as "sonic", a global term for all sound effects and elements used in a sweeper.)
Sweepers are also known as liners, bumpers, radio imaging, sweeps, station imaging, stingers, IDs, idents, promos, shotguns and intros. All sweepers will have a voice over included on the audio.

Famous quotes containing the word radio:
“England has the most sordid literary scene I’ve ever seen. They all meet in the same pub. This guy’s writing a foreword for this person. They all have to give radio programs, they have to do all this just in order to scrape by. They’re all scratching each other’s backs.”
—William Burroughs (b. 1914)
