What Is a Sweeper in Radio?

A sweeper is a short, produced voice clip played over the transition from one song to the next on radio, typically three to eight seconds long. It "sweeps" the listener from the end of one track into the start of the next while restating the station's name, slogan or attitude, so the segue is branded rather than silent.

Why sweepers exist

Radio programmers want the station's identity present as often as possible without interrupting the music. The few seconds where one song ends and another begins are the natural place. A sweeper fills that gap with a brand message and makes the segue feel deliberate. On music-intensive formats, a sweeper every two or three songs is normal.

What a sweeper contains

• A line: the station name with a slogan or an attitude statement, such as "the hottest hits, back to back".
• The imaging voice, processed to cut through the end of one song and the start of the next.
• Effects: stutter, reverb and echo are the classic chain; whooshes and hits are added in the mix.
• Timing: the line is written to finish just before the vocal of the incoming song starts.

Sweepers are often produced in families: the same voice and chain with twenty different lines so they rotate without repeating.

Sweepers in DJ sets and streams

A DJ drop fired during a transition is a sweeper. Mixtape DJs use them to brand the mix at each blend; stream DJs use them as bumpers between tracks. The rules are the same as radio: keep it short, land the last word before the incoming vocal, and keep the chain consistent so every sweeper sounds like the same brand.

Making sweepers in Club Ready Music

In the Drops studio:

1. Script. One line, up to 200 characters: the name plus an attitude or a slogan. Write several scripts and render each so you have a rotation.
2. Voice. Imaging for the classic radio sweeper; Hype for club-style energy; Smooth for late-night formats; Robotic for electronic shows.
3. FX. Reverb tail and Stutter are on by default. Add Echo for a tail on the last word.
4. Bed. Dry if the sweeper plays over music, which is the usual case. Impact hit or Riser if it plays in a gap.
5. Length. 5 seconds for most sweepers; 3 for a tight one; 10 for a longer line into a show.

Each render gives three variations so the rotation grows quickly, plus a dry voice version of each so you can build your own chain if you prefer. Every file is leveled to -8 LUFS so the sweeper is never quieter than the songs around it.

Writing lines that work

Short words, present tense, one idea. "Non-stop hits, all night, on Pulse FM" reads in under four seconds. Avoid lines that mention a time or a day unless you are making a dated promo, because a good sweeper is played for months.
