Sometimes, voice-tracking is done so that people can do other jobs. For example, a DJ may also have a job as a program director or general manager. Voice-tracking allows that person to record a three-hour shift in less than a half-hour, leaving him or her time to do office work. A popular live weekday morning radio host can record parts for a Saturday show, allowing him or her to be on the air six days a week without spending more time at the station. It is also helpful during holidays such as Christmas or Easter, when people are off spending time with their families.
