Audio drama (or radio drama, audio play, radio play, radio theater, or audio theater) is a dramatized, purely acoustic performance. With no visual component, radio drama depends on dialogue, music and sound effects to help the listener imagine the characters and story: “It is auditory in the physical dimension but equally powerful as a visual force in the psychological dimension.”
Thanks to advances in digital recording and Internet distribution, radio drama was experiencing a revival in 2010.

Not to be mistaken with an audiobook, with an audiobook all lines from the book a read out and spoken lines are done with different voice actors. With an audio drama you get a full experience with soundeffects and added atmosphere.

There are two audio drama’s based on Joe’s work:

Locke & Key

The Devil On The Staircase
