Glitching can also mean that a system, such as a computer, is experiencing many glitches and technical problems at once.
"My comp is glitching out again, dammit."
"Glitching the character creation menu is weird, it causes every NPC in the game to turn inside out."
"If I am glitching too much in that game it causes a BSoD and my computer stops working for a few hours."
"Stop glitching or I'll ban you from the server!"
Glitching most commonly refers to sound experiments, but can be used to describe other digital sensory alterations, as well as future experiments using technology not yet available.
The term originated in Boston by psychonauts experimenting with altered listening. The name comes from VST plugin Glitch, with which the original experiments were performed.
Basically, it involves running a microphone through an effects processor and listening to it through headphones. The result of experiencing the world like this leads to an altered state of awareness.
Visual glitching can be done with a camera and video goggles. Glitching can be interfaced with EEG brainwave technology (such as the Emotiv Epoc) to create a feedback experience. Future glitching will make use of technology as it becomes available (such as Augmented Reality). Glitching can also be networked between many glitchers, even over the internet, to induce Massively Multiplayer Online Psychedelic Experiences (MMOPE).
Glitching is sometimes seen as an alternative to Mind-altering drugs, but can be used in synergy.
Microphone + headphones + laptop + backpack + Ableton Live + VST effects = Glitching.
