Databending (or data bending) is the process of manipulating a media file of a certain format, using software designed to edit files of another format. Distortions in the medium typically occur as a result, and the process either falls under a broader category of, or is frequently employed in glitch art.
The term databending is derived from circuit bending, in which objects such as children's toys, effects pedals and electronic keyboards are deliberately short circuited by bending the circuit board to produce erratic and spontaneous sounds. Like circuit bending, databending involves the (often unpredictable) alteration of its target's behavior. Databending achieves this alteration by manipulating the information within a media file of a certain format, using software designed to edit files of a different format; distortions in the medium typically occur as a result. Many techniques exist, including the use of hex editors to manipulate certain components of a compression algorithm, to comparatively simple methods.
