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:
“Having a thirteen-year-old in the family is like having a general-admission ticket to the movies, radio and TV. You get to understand that the glittering new arts of our civilization are directed to the teen-agers, and by their suffrage they stand or fall.”
—Max Lerner (b. 1902)
