Class: The Audio Adventures

Class: The Audio Adventures was a series of audio stories centred around the Doctor Who spin-off Class.

All six regular actors returned voicing their characters for the first two volumes. Due to availability issues for volumes three and four, Andrea Quill and Tanya Adeola were recast as Dervla Kirwan and Joanna McGibbon respectively. The series also saw the return of Ace and the Daleks, after their previous visit to Coal Hill in 1988's Remembrance of the Daleks. Patrick Ness, who created the show and wrote its first series, was involved with the storyline and scripts of the audio series, despite not writing any of the stories.

"Up All Night" couldn't be used as the theme tune for the series due to rights issues so instead the stories opened using the 'Class Credits' music, that had been composed by Blair Mowat to play over the closing credits of the TV stories.

Because the licence was acquired before the show's cancellation, the audio stories for through  couldn't develop the cliffhanger of the first series' final episode The Lost, as they might have created a conflict with a potential second series, which never came to be. Thus, as of 2020, all stories being developed for this series needed to take place between the events of the show's first series. Queen of Rhodia, capping off Volume Four, takes place furthest along the timeline, between The Metaphysical Engine, or What Quill Did and The Lost.
