Disc jockey

A disc jockey (abbreviated DJ, D.J. or deejay) is a person who plays recorded music for an audience, either a radio audience if the mix is broadcast or the audience in a venue such as a bar or nightclub. In venues such as a club event or rave, this is an audience of dancers. Originally, "disc" (uncommonly spelled "disque" in French or commonly "disk" in American English) referred to phonograph records, not the later compact discs. Today, the term includes all forms of music playback, no matter which medium is used (e.g. vinyl, CDs, MP3 players).

The title "DJ" is also commonly used by DJs in front of their real names or adopted pseudonyms as a title to denote their profession and the music they play.

Types

There are several types of disc jockey. Radio DJs or radio personalities introduce and play music that is broadcast on AM, FM, digital or internet radio stations. Club DJs select and play music in bars, nightclubs or discothèques, or at parties or raves, or even in stadiums. Mobile DJs travel with portable sound systems and play recorded music at a variety of events. Some mobile DJs also serve as the master of ceremonies (MC) directing the attention of attendees, and maintaining a room-wide focus on what is included in the event's agenda. There are also many competitions that specialise in mixing, scratching or other kinds of techniques.

Radio personality

A radio personality is a person who has an on-air position in radio broadcasting. A radio personality hosts a radio show is also known as a radio host and in India and Pakistan as a radio jockey.

Description

A radio personality can be someone who introduces and discusses genres of music; hosts a talk radio show that may take calls from listeners; interviews celebrities or guests; or gives news, weather, sports, or traffic information. The radio personality may broadcast live or use voice-tracking techniques.

Increasingly, radio personalities are expected to supplement their on-air work by posting information online, such as on a blog. This may be either to generate additional revenue or connect with listeners.

With the exception of small or rural radio stations, most of what you hear on the radio now is a computer-controlled playlist airing .mp3 audio files. These audio files are the source of the songs you hear, the commercials, and half the time even the radio announcer himself has pre-recorded a "break". Essentially, most radio stations are PC's playing audio files and broadcasting the signal on-air.
