The BBC Radiophonic Workshop produced many albums and many tracks, incidental music pieces for many programmes.  These include complete theme tunes, to radio jingles, to whole sections of incidental music.  Naturally, they also provided (and invented) the voices of the Daleks, Marvin the Paranoid Android and many, many sound effects from opening doors, to rockets in flight.
