In 1966, an abridged recording of episode 6 of
The Chase was released with narration on a 7-inch record. In 1979, the
BBC released an abridged version of
Genesis of the Daleks. In 1992 a brief series began releasing audio versions of missing stories from the archives, with link narration provided by one of the actors who played
the Doctor. The soundtracks that were known to exist at the time were not the optimal audio quality and the range only released a few stories. A second series of "Lost Episode" soundtrack releases began in 1999. This series differed from earlier releases by having "linking" narration (to describe action and other sequences that were originally visual) read by an actor or actress who had played a companion in the original serial, rather than one of the actors who played the Doctor (except
The Macra Terror, which used the original narration by Colin Baker). Another difference is that all the later releases were remastered for release by Mark Ayres from tapes recorded "off-air" at the original time of broadcast, or, when necessary, due to quality and possibly availability, from surviving films. From 1999 to 2004, these recordings were released under the "BBC Radio Collection" banner, and, starting in 2004, they have been released under the "BBC Audio" banner, with different outer packaging. The series was officially completed in 2006 with the release of
The Reign of Terror; however, a rerelease of the soundtrack for
The Tomb of the Cybermen was produced and was followed by new audio productions of available serials. All have been released by the BBC unless otherwise noted. This list is in order by release date. ==Audio drama==
