generative audio installation, 2020/21
2,5m cube, latex foil, motors PD-0.50-2
with Leo Peschta
The sea is an auditive and visual sculpture, configured as an open, never repeating process of audio waves.
An elastic latex foil is stretched between 4 linear axes driven by stepper motors dividing the space in 3 dimensions. The shape of the sculpture relates to generative processes connected to a DSP-audio platform and the scheduler for the motor movement on the 4 axes of the cube.
The Sea is an extraction of a complex natural phenomenon resulting in an artificial emulation, developing a life-form of its own. Like the ‘real’ sea as an endless repetition of waves, a natural system which results in complex variations over time, it follows the impact of an immersive state, leading to a dystopian vision of an artificial generator. The combination of the stretched foil and the evolvement of the sound result in a highly dynamic, but only seemingly chaotic system, able to generate associations that range from the swell of the ocean to a science-fiction setting. But it should also enable the viewer to perceive the latex foil for what it actually represents - a vibration floating in space.

Acoustic Shadows is an implementation of a complex adaptive system in an eco-systemic configuration. Through the implementation of a feedback system in the high-frequency domain, signals that oscillate at the threshold of the human perception are ‘scanning’ the area. Shadows or inaudible signals, which are created by human presence are influencing the state of the system and therefore change its behaviour, perturbing the system’s microphone-loudspeaker connection and self-modulation. The adaptations could be perceived more like a ghostlike appearance then an interactive reaction.
As an adaptive technological life-form, which spreads discretely but invasively, filtering it’s environment, it could be perceived through the presumption of it’s inner process. A circular system, that reacts to external influences, but also develops a life of its own. Almost like an abstract occult machine that meters the space to extend its own state.

‘Unterm Pflaster liegt der Strand’, in it's original french version of "Sous les pavés, la plage" is attributed to the situationists. The phrase became one of the most popular slogans of the 1968 revolt around the world. ‘Unterm Pflaster liegt der Strand’ alludes to the fact that paving stones were often laid on a sand underground, and is also an invitation to use them. This slogan combines hedonism with activism.
With minimal resources, the display is staged as a museum view and placed in the context of activist action. The text is translated to latin, so it resembles often used honorable mentions on arcades and city monuments.

acknowledgments: Tokyo Arts and Space, Ulla Rauter, Paul Reza Klein
MONO-NO-KE is part of a series of works that deal with the transmission of sound and appearance of sound events relational to space. It draws its starting point from observations in the Sumida area in Tokyo, where plastic water bottles standing next to the houses, manufacturer buildings, or hidden in the corners or in the front of stores, are used as an everyday custom to scare cats and beasts away, apparently a NEKO 'yoke'. It is also connected to the belief in Yokai and Mononoke, which combine imaginary and scientific explanation about natural phaenomena and ghost like appearances, originating from old stories of the Heian period, but occurring again in current sci-fi, manga and game culture.
Reflections and Refractions of a laser that scans plastic bottles are translated to sound through the interpretation of the refracted light. Sound is not generated but shaped by the appearance of light schemes in space. Refracted by the laser, detailed but always changing shapes appear. Those images are captured by a web-camera and translated via an IFFT process which results in an audible synthesized sound.

Tuned City, organised by Carsten Stabenow
Ancient Messene, Mavromati, Greece
Natural radio frequencies, that are caused by meteorological phenomena, are transmitted by a laser through the Arcadian Gate of Ancient Messene and received on the other side of the walls by a solar cell amplifier. The detected sound is diffused by a loudspeaker and resonating through the gate.
The western Gate of Ancient Messene, called Arcadian Gate, is preserved in relatively good condition and since the time of the early travelers it has become the symbol of the city depicted repeatedly on engravings. The Arcadian Gate is a monumental construction built of gigantic awe inspiring limestone blocks. Its shape is circular with two entrances, a double one in the interior and an external one, the latter being protected on either side by two square-shaped towers. The circular area inside the Gate has two niches, one on each side of the entrance where a Hermaic stele stood. God Hermes appears under his capacity as Propylaios, that is, the protector of Gates. Above the north niche one can read the following inscription: Κoιντος Πλώτιος Ευφημίων επεσκεύασεν Cointus Plotius Euphemion restored (the Gate).

made possible by Wan Lianxi letting fly his flock of pigeons, pigeonflutes by Wang Yongsheng
with the support of Shayan, Yi-Chi Wang and TGIS
The video shows a 360 degree scan of an Hutong area in Dashila, Beijing. It is considered a ‘red flight zone’, where the use of drones is prohibited due to the proximity to forbidden city and Tiananmen, Beijing. The old Hutong quarters are quite narrow and form a complex mesh of adaptions to the old traditional buildings, that organically grew over the years, that they have been open to the people. On some of the houses rooftops flocks of pigeons have their shelter. Those pigeons are mostly trained to participate in pigeon racings, and are therefore held with a lot of care, as pigeon racing turned out to be a gambling sport, that is also connected to wealthy people and yield high profits. It is said that the main goal for flight competition is not about money but honour, but there seems to be an evolving business going on with pigeon breeders, traders, pirating and betting offices. A worldwide market that evolved especially in China to unite economical, cultural, social and industrial interests to breed the best pigeons to achieve victories in the races. Besides this interest, there is the old tradition to let pigeons fly with special designed flutes, that get attached to the tail of the pigeons. Some of the flutes date back to the Qing dynasty and are still remade as collectibles to value the old handcraft. There are four types of whistles - tube, star, calabash and stareye types, that produce drone like tones up to pentatonic scales. When a flock of birds flies with the flutes attached, it appears as they mark a territory by circling in a certain orbit, diffusing the flute sound in a 3 dimensional spacial way.

this project was supported by the Embassy of Austria in Chile, BKA, and SKE - Austro Mechana
Very low frequency signals (VLF-signals), which are can be caused by meteorological phenomena such as thunderstorms and lightning, were detected by a kite with an antenna and made audible through the use of a high sensitive transistor amplifier. The recordings were taken during a research trip in southern part of Chile and on Cape Horn.

Sound intervention during the festival Tsonami. The audience was invited to eat fried fish with the seagulls at the port.
"fishers feed the audience, the leftovers are fed to the seagulls (as usual), which feed the audience with their sounds." (quote by Nicolás Spencer)
First you have to agree, what is a “Picá”? In Chile they call “Picá” restaurants, Fuentes de Soda or cooks that offer typical Chilean recipes, with abundant portions and at a good price. Generally they are tips that are passed from mouth to mouth, popular places, with an environment that is part of the national identity. It is simple, simple food, with all the flavor of local cuisine, since most have been cooking and refining the same dishes for many years.

Site Specific - Light Installation, 2017
fluorescent tubes, cables, metal/wood structure, electric current
In cooperation with Ye Shangda
assistance: Hu Xinru, Chao Fu-Le
As a site specific intervention the Attractor is built in a public space, connects to its surroundings and reacts to changes in the electric field. In certain areas in Feijiacun, due to power poles and electrical substations, electric fields build up and can be detected with strip light. They are shaped by the constellations of the architectural setting. Different expansion is found on flat spaces, next to houses, near to trees or on rooftops. The sculpture is not connected to power, but lighted by the electric current it is surrounded by and detects the disturbances when people are passing. It deals with the processes happening in transitory areas and reveals signals that seem to be hidden from general perception.

Triptychon of lost media - II, Flash, AM-Feld / Soviet Noise
Audio Visual Installations, 2016/17
radio, transmitter, electric current, camera flash, micro controller, relais, electromagnetic field
Flash is an audio-visual installation for camera flash, radio transmitter and changing electric current, shown in the last exhibition of Black Bridge artist village in Beijing, before it got abandoned due to re- structuring of the region. The flashes interfere with the electromagnetic field and thereby influence the signals detected by the radio receivers. The fluctuations of the power grid, which occur quite frequently in Beijing, push the radio transmitter out of resonance and produce an unstable field.
The project AM-Feld / Soviet Noise, is a cooperation with Alexander Felch which took place in St. Petersburg. It is the second part of the series ‘Triptychon of lost media’ and concerns the examination of emitter and receiver and explores extended techniques of sound generation and playback. The theme ‘emitter-receiver’ is the conceptual theoretical framework for the work series, but also correlates to the applied techniques of how sound and material are shaped. For ‘AM Field / Soviet Noise’ a radio signal was created to transmit 30 minutes of empty audio tapes, produced 1989. Portable radio receivers where supplied to detect the signals of the audio tapes from the ‘soviet environment’. The work is referencing russian protagonists like Velimir Khleb- nikov (author of the futuristic essay ‘radio of the future’), Alexander Stepanovic Popov (pioneer of radio technology) and UVB-76 (a short wave transmitter, sending a buzz tone since ~1975). There are several portable radio receivers in the room, whose position can also be changed by the visitors. The installation is based on the idea of the Acousmonium, a multi-channel loud- speaker sound system developed by Francois Bayle in the ‘Groupe de Recherches Musicales’ for Radio France 1974. But in contrast to the concept of a composition for fixed loudspeakers, the visitors, equipped with a portable radio receiver, are the players of a ‘loudspeaker orchestra’ themselves. They can move with the radio receivers in the zone of transmission. Several short- range transmitters, all at the same transmission frequency, are positioned at different locations in the room. Each transmitter covers a specific area, which can be received separately, but also modulated by possible interferences. The various transmission distances can be monitored by the movement in the space, thus resulting in a constantly changing configuration.

Kanaldeckel is referring to an action that is needed to explore a different layer within the urban landscape, and could stand for an entrance point moving to another dimension in space. Following the slogan: “Unter dem Pflaster liegt der Strand”, a manhole was transferred from its original position, to create a gateway to stroll around for some time.
After hacking into the radio frequency of the Mercedes Benz car, available at Antwerp gallery fp24, this mobile soundsystem was used to diffuse hidden frequencies, HF-and VLF-signals, and modulated low oscillations.

metal plates, contact microphones, transducers generate feedback.
in cooperation with Christoph Freidhöfer
This is the first part of the series ‘Triptychon of lost media’. It deals with the examination of emitter and receiver and explores extended techniques of sound generation and playback. The theme ‘emitter-receiver’ is the conceptual theoretical framework for the work series but also correlates to the applied techniques of how sound and material is shaped.
Metal plates are used as tone generators as well as loudspeakers due to feedback that emerges from applying transducers and contact microphones to the surface. Due to the more or less chaotic vibration of the metal sheets and low amplification, the spectrum moves between the sound of fanfares and thunder. The installation deals with the propagation of sound in space and feedback between transmitter and receiver.
The project was developed for moe, Schaukasten XII and took part at the sound-festival unsafe+sounds in June 2015.

- investigation and interaction with audio-visual material. Fragments of organisms such as lichens or tree bines and geological samples of a collection compiled by Claudia Larcher in the border region between Europe and Russia, on the Lithuanian peninsula Neringa, are categorized according to an abstract cartography. The material is re-arranged with the help of microscopes, contact microphones, coils, camera airbrakes, thus surveying the boundaries of scientific, geographical or geological aspects in a different context.
Speech - Intervention - Animal, 2013 - ongoing
loudspeaker, parabolic microphones, micro controller, motor
in cooperation with Christoph Freidhöfer
The robot moves around the exhibition space, orienting itself based on the events, records the speech of other visitors and articulates clever sayings. Using its two parabolic microphone ‘ears’ with the help of the shielding function of the foam ‘hairstyle’ it listens to the most interesting events and moves in direction to where it suspects appealing things to happen. There the robot takes on its journey, remembering snippets of conversations. Otherwise it is striking sayings like ‘the most popular occupations for men and women’ or a quote from ‘Alte Meister’ by Thomas Bernhard.

Pachinko is played by more than 30% of the Japanese population. It is based on the coincidental spreading of Pachinko balls hitting certain positions, which lead to winnings. A peculiar feature in Pachinko game halls is the volume and the chaotically fluctuating sound. With this automaton the sound of the surroundings and the Pachinko itself is recorded, triggered, generated and manipulated in realtime without the use of prerecorded sounds (except one tribute-soundfile). Controlled by sensors, the Pachinko becomes an uncontrollable and absurd interface, as you never know what the machine will do next.

in cooperation with Paul_Reza Klein
A toy police car falls in free fall at the exhibition Dimensions Variable # at Mo.ë. When the car is switched on, the car‘s flashing lights start flashing and it sounds: ‘Police, do not move - [sound- effect: gunshot] - you are under arrest!’ The car is equipped with a conductive cable on a coil that is attached to the ceiling. At random time intervals, the car falls from the ceiling to shortly before the impact on the ground.
taperecorder, oscillators, frog
Description of the setup:
The sounds of a cassette recorder, a simple oscillator circuit and a wooden frog are recorded on an empty tape loop. The name Wilhelm‘s Punk refers to the piece Williams Mix by John Cage, in which pre-recorded and selected sounds are mounted on tape by a random system. For Wilhelm‘s Punk, sounds, which are produced during the performance are played on the tape loop and reproduced immediately. Each loop replay plays the already recorded fragments, takes up new ones and deletes older parts by accident.
Composition for violin, grains on a metal surface and live-electronics ~8‘ , 2012
[violin is played by Barbara Lüneburg, recorded at Echoraum, Wien]
The piece consists of singular tones that fill the space horizontally and create a quiet ubiquitous drone. Filtered noise areas, quiet creak, some prominent sound particles, (no open strings), minimal timbre (out of a grayscale evolve „colours“), microtonality vs. widely spaced intervals, grains, ..
The pitch of the violin results from the vertical position of the note within the score; i.e. high frequencies - low frequencies. The timeframe is also relative. The task of the electronics is to extract individual sections from the played parts of the violin and to filter them slightly by means of pitch shift or synthesis. Due to the division into 4 channels there are focal points, but they are selected loosely. The notation makes suggestions for this, but these are understood as indications.

Site Specific Installation, 2008
The installation “Zweistimmige Inventionen” has been designed for the Prospekthof Semperdepot of the Academy of Fine Arts Vienna and consists of the following components:
A swing from a playground that was extended with hawsers (ropes) from the roof framework to the ground.
A hi-fi system / ghetto blaster.
The recordings of the fifteen Two-Part Inventions and one Three-Part Sinfonia of J.S.Bach, which I have learned for this work and recorded myself.
A framed image that shows the wooden framework for a swing at a playground, where the swing is missing and the ground is covered with additional soil.
Considerations to the themes, areas and associations, which could form some of the questions the Installation “Zweistimmige Inventionen” poses, are accompanying the work as a virtual art-theory handout.

The video shows the traces of the tires of a bicycle, during a ride through the city. The traces appear like oscillating lines that lay over the erratic movements and interferences of the structure of the ground. The audio track gives an anticipation of the urban surrounding, interferences between the noise of the pedals and the events on the street occur.
