In the radio industry, an aircheck is generally a demonstration recording,
often intended to show off the talent of an announcer or radio programmer
to a prospective future employer.
A scoped (telescoped) 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,
commercials, newscasts, jingles and other on-air events.
Another category of airchecks are those recorded "off-the-air" using consumer
or semi-professional equipment.
These airchecks became more common with the advent of radio-cassette
