Sinopsis:
A young man uses supermarket-style 'musak' to induce frightening reactions within people. 'Musak', by its very nature, has undoubted political significance. With this in mind, the authors of Decoder have concentrated on achieving a blend of reality and fiction: surreal, metaphorical imagery interwoven with music, words and sound effects make this a musical/action movie with a very real physical impact.
Activismo, futuro alienante y totalitario , cyberpunk en definitiva, Burroughs, Genesis P Orridge, Einsturzende Neubaten... no se, casi mejor os pego una review de un festival que he encontrado por ahi y unas fotos para q os hagais una idea:

Decoder
The German film Decoder by Klaus Maeck was, despite the lack of subtitles, the highlight for many at the festival. "Muzak is more than music." A young punk (FM Einheit of Einstürzende Neubauten) lives in a dark, apocalyptic and alienated world. While eating at a H Burger restaurant Einheit notices the pacifying contentment of the 'Muzak' provided in the fast food restaurant. He wonders if there is a connection between this monotonous Muzak and the passive and unresisting acceptance of junk food and junk culture. He considers the omnipresence of this Muzak, not just in H Burger restaurants but in shopping malls, elevators, car radios and discos and wonders if there is an intrinsic link to mass social control and inertia. What becomes apparent to him, is that the use of subliminal thought control messages has the the effect of giving the subject the impression, that it is their very own ideas.

His girlfriend (the real Christiane F of the film Christiane F, wir Kinder vom Bahnhof Zoo) is obsessed with Frogs and works at a Peep show, where she has attracted the admiring interest of the lonely Jager. The relationship between Einheit and Christian F is distant and not intimate, they recount their dreams over breakfast. In a dream sequence William Burroughs encounters Christian F in a Jarmanesque city dump, they wonder off to the sound of 1000 tape recorders fading out. Einheit returns to H Burger and records the music, which he later experiments with back in his loft. Is it possible to reverse the effect of this music, to discover anti-Muzak? He visits an electronics repair shop run by William Burroughs. Wondering the city, Einheit comes across a group of urban pirates lead by Genesis P-Orridge, who appears with a shaven head and wearing a Priest collar (a very apt parody of himself). The pirates have taken over a disused building (dispersed with open fires) to conduct black-noise masses. Einheit records the sounds of the pirate-mass, but the pirates capture the infiltrator and bring him to face a dream machine. Genesis P-Orridge philosophises that we are in an information war, where information has become the new economy and power is obtained in the abundance of information. The strategy is, "information to short-circuit information."

The pirates are however just as intrigued by Einheit's ideas and begin to collaborate. Einheit experiments with this newly developed anti-Muzak in H Burger restaurants (and McDonalds) causing mass nausea amongst patrons, causing them to charge towards the exits. The experiment is repeated all over the city and the Muzak Corporation responds by sending its agent, Jager to hunt down the source of the cassette terrorism. In his infatuation with the erotic dancer Christian F, Jager is unaware that he is already closing in on his suspect. The cassette tapes are spread throughout the city causing mass sickness, rioting, civil disobedience and chaos. Video footage of the Berlin May Day riots are utilised here to effect.

The film includes music by Soft Cell, Sleazy City and Einstürzende Neubauten's, Compressed Metal. Einstürzende Neubauten's Maifestspiele from 1989 is also a reference with its field recordings made in the May Day riots of 1987. The ideal accompanying film to Decoder would certainly have been Der Platz directed by Uli M Schüppel, a documentary on the building works at Potsdamer Platz in Berlin with music by FM Einheit.

To emphasise the real impact of sound and its potential psycho-emotive force, it is worth recalling that the French initially conducted research in the 1930's on the development of a sound cannon for military use. Such a cannon, it was hoped would project ultra sound frequencies, of which 7 Hertz is the most dangerous to human life, and coincidentally at that frequency also inaudible. "...the man who first found out about this died finding out about it. He was in the studio and generated 7 Hertz and it literally curdled his insides." 2 But don't worry, no conventional recording medium or radio transmission can project these frequencies. The film employs the cut-up tape recorder experiments of William Burroughs (outlined for example in The Revised Boy Scout Manual, The Electronic Revolution and The Job) to bring about this political and cultural upheaval. Burroughs suggests we should use subliminal messages, recorded riot sounds, fake news broadcasts, bomb blasts, accidents, assassinations and cut-up sex sounds... record response, move quickly and playback in new location.

A juzgar por el elink esta en krautlange y sin subtitulos a la vista, hay abundantes fuentes completas.
