The document discusses the equipment needed to produce radio advertisements, including a mixing desk to mix music and alter pitch, a soundproof recording booth to record high quality audio without outside noise, and audio editing software to modify sounds. It notes that renting a soundproof recording studio costs around £900 per hour on average. The document also describes the radio station at the author's college, E6 Radio, which has its own music library and equipment like a mixing desk for combining songs and altering sounds. It compares different audio editing software programs, noting that while Adobe Audition is professionally used, the free and open-source Reaper has sufficient features for students' college radio work.
