Aircheck
In the radio industry, an aircheck is generally a demonstration recording, often intended to show off the talent of an announcer or programmer to a prospective employer, but mainly intended for legal archiving purposes. A scoped (short for "telescoped" - by analogy with pressing the ends of a hand-held telescope to reduce its size) aircheck usually contains only segments where the announcer is actually talking, along with a bit of the music or commercial on either side. In an unscoped aircheck, all programming is left intact and unedited, including music, commercials, newscasts, jingles and other on-air events.
