Cloud Sequencer

A new work by Ronald van der Meijs.

Notes from the author:

This project is a first start for a new sound research project into the diversity of clouds, sun and wind in order to create a sort of ‘natural sequencer’ for an outside sound installation. This site specific instrument consists out of seven solar powered bass organ pipe units interacting on the brightness of the sun to control the loudness of the sound. In this way passing clouds form a natural sequencer for this installation. Each organ pipe unit is catching the wind with one of the 5 smal sails, controlled by a system of pulley wheels and counter weights for pitching the sound of each organ pipe by a moving valve.

The weather conditions of the island determine how the sounds and its composition evolves as a constant changing requiem for the West Vlieland village which disappeared into the North Sea in 1736. As for this village the installation is completely handed over to the unpredictability of the weather. This plays a major part in the concept of this sound installation; one has to accept the weather conditions in al its appearances. This means that it needs sun, clouds and wind to produce a variety of sounds. So if there is no sun at all there is no sound to produce. What is left in this situation is the sound of nature itself.

The work has been installed on the Dutch island of Vlieland (53°18’02.3″N – 5°05’12.0”E) from July 22th to aug 30th 2017

Nel 2002 il compositore scandinavo Leif Inge ha realizzato digitalmente una espansione temporale della Nona Sinfonia di Beethoven portandola alla durata di 24 ore, senza distorsioni o variazioni di altezza. Considerando che la durata normale della Nona si aggira intorno ai 67 minuti (ma dipende dal direttore: può anche superare i 70′ e arrivare fino a 77’16” nella versione di Kubelik del ’74), si tratta di una espansione di circa 21.5 volte.

Il titolo del brano così ottenuto è 9 Beet Stretch e suona come un continuum sonoro in lenta evoluzione, ma non così lenta da non permettere di percepire cambiamenti in tempi ragionevoli (qualche minuto al massimo, ma generalmente in tempi più brevi). Ovviamente, con questi tempi, la melodia si perde completamente e il tutto si trasforma in una sequenza di accordi, ma è interessante notare come il senso drammatico dell’armonia in gran parte rimanga.

Gli attacchi delle note sono tutti molto graduali perché non si tratta di una esecuzione rallentata, ma di uno stretching del segnale audio, quindi un attacco che in originale dura 1/10 di secondo, nella versione espansa dura 2.15 secondi. La versione utilizzata è una registrazione Naxos diretta da Béla Drahos con la Nicolaus Esterházy Sinfonia e Coro (Naxos 8.553478).

Lo stream si può ascoltare via internet dal sito di riferimento avviando il player. La trasmissione inizia all’ora in cui il sole tramonta a Vienna il 26 Marzo (le 18:16 CET), giorno e ora della morte di Beethoven, e continua 24/7. Di conseguenza, nelle giornate di ora solare, i quattro movimenti hanno i seguenti tempi di inizio (CET = central europe time, cioè il nostro fuso orario)

  • CET 18:16 movement 1 – duration 5½ hours
  • CET 23:43 movement 2 – duration 5 hours
  • CET 04:48 movement 3 – duration 5 hours
  • CET 09:24 movement 4 – duration 8½ hours

Nel periodo di ora legale, dovete aggiungere un’ora.

Outings Project

Outings is a global participative project, initiated by Julien de Casabianca, a French visual artist and filmmaker.

Anyone in their own town can go to their museums, take pictures of portraits with their phones and set them free.

It’s also museums, schools and cities organizing themselves with the inhabitants of their towns.

Eventually it’s exhibitions in museums and galleries of the photographs Julien de Casabianca took of his own Outings and shot all around the world.

Nabaz’mob

In questo post, la storia di Nabaztag è tratta da Wikipedia, con qualche nota del sottoscritto.

La parola Nabaztag (“նապաստակ” che in lingua armena significa coniglio), indica il coniglio wifi ideato da Rafi Haladjian e Olivier Mével e prodotto, nel 2005 dalla compagnia francese Violet.

Alto 23 centimetri, per un peso di 418 grammi, dispone di svariate abilità, tra le quali dare le previsioni del tempo, declamare le ore, segnalare eventuali messaggi di posta elettronica e illuminarsi per mezzo di LED colorati, muovendo le orecchie e pronunciando imprevedibili battute. Può inoltre riprodurre messaggi testuali ed MP3. Con il passare del tempo altri svariati servizi sono stati implementati. È inoltre scomparsa la distinzione tra servizi base e servizi su abbonamento, anch’essi divenuti gratuiti. Esistono anche dei servizi sviluppati dagli stessi utenti (musica, notizie, curiosità) denominati “Nabcast”.

L’oggetto, venduto a partire da giugno 2005, alla fine di ottobre 2006 aveva raggiunto i 35.000 esemplari nella sola Francia. A fine 2006 viene introdotto un modello più avanzato, il Nabaztag:tag che supporta lo streaming mp3 via internet, ha un microfono per ricevere comandi vocali e un lettore di RFID con tag personalizzati per ricevere comandi. Questo modello, inoltre, è dotato di tecnologia PULL, ossia può interrogare il server di propria iniziativa. A settembre 2007 sono presenti più di 180.000 Nabaztag in tutto il mondo.

Il 20 ottobre 2009 Violet, in difficoltà per una gestione dissennata, è acquistata dal noto software publisher Mindscape che immette sul mercato un modello ancora più avanzato chiamato Karotz con webcam e maggiori capacità di memoria. Ben presto, però, anche quest’ultimo entra in crisi. Il 29 luglio 2011 Mindscape comunica lo spegnimento dei server di gestione di Nabaztag creando in un solo colpo 180.000 orfani, ma rende pubblico il codice per la gestione dei “coniglietti” multimediali, rendendo possibile a diverse comunità utenti di creare dei nuovi server. Comunque, le varie comunità utente hanno privilegiato soluzioni alternative, basate sui progetti Opensource OpenJabNab, Nabizdead e OpenNag, più semplici da implementare dell’originale server (denominato “burrow”, con riferimento alle tane dei conigli selvatici) Violet/Mindscape ma privi del supporto per le vecchie unità Nabaztag di prima generazione. Le comunità utente sorte nell’immediata chiusura del server “ufficiale” supportano infatti i soli Nabaztag:tag.

In seguito Mindscape è acquisita da Aldebaran Robotics, azienda specializzata in robot giocattolo ed amatoriali, che vende ad esaurimento le scorte di Karotz senza sviluppare il prodotto, malgrado esso avesse incorporati e ben visibili evidenti agganci per accessori ed estensioni. Infine, con un annuncio scioccante del suo CEO comunica lo spegnimento dei server dei Karotz per il 18 febbraio 2015 segnando, così, la fine del progetto la cui esistenza resta affidata ai server amatoriali.

Dalla creazione di Nabaztag, Antoine Schmitt ne è il designer comportamentale e Jean-Jacques Birgé il designer sonoro. Insieme, hanno anche composto l’Opera Nabaz’mob per 100 conigli tra loro comunicanti, che ha vinto il Prix Ars Electronica Award of Distinction Digital Musics 2009 e di cui si può vedere un estratto in questo video.

nayral-ro

Un altro lavoro di ::vtol::

The orchestra consists of 12 robotic manipulators of various designs, each of which is equipped with a sound-transmitting speaker. The manipulators, combined together, form a single multi-channel electronic sound orchestra. Due to constant displacement speakers in space, changing direction of the sound and the algorithms for generating compositions, the orchestra creates a dynamic soundscape. In order to interact with the orchestra, controller Leap Motion is used, that allows to control robots and sound by simple hands gestures in the air – similarly to conducting an orchestra.

The project is based on the idea of a combination of modern music, computer, interactive and robotic concepts and approaches for the creation of works of art. In many ways, it is inspired by well-known works that were presented in the recent past, such as Pendulum Choir (2011) and Mendelssohn Effektorium (2013). However, Nayral Ro is different from these projects in many ways. Its algorithmic system, in which sound and musical composition are being produced, is real time, and the acoustic environment also changes simultaneously with the process of creating the musical piece. Also, the whole process is completely subordinated by the “conductor”, so this a role is similar to such of a composer, performer and operator at the same time.

Creation of more sophisticated versions, more subtly revealing the potential of Leap Motion for tuning to the movement and changes in sound, is being planned for the future development.

Metaphase Sound Machine

Questa splendida e inusuale macchina sonora è stata progettata e costruita dal media-artist russo Dmitry Morozov (aka ::vtol::).

The Metaphase Sound Machine is a kind of homage to the ideas of the American physicist Nick Herbert who in the 1970s has created both Metaphase Typewriter and Quantum Metaphone (a speech synthesizer). These were some of the first attempts to put the phenomenon of quantum entanglement in practice and one of the first steps towards the creation of a quantum computer. The experimental devices, however, had not confirmed theoretical research, and Herbert’s obsession with metaphysics resulted in the publication of several of his works on the metaphysical in quantum physics, that have led to a serious loss of interest to the ideas of quantum communication. One day, in a course of his experiments, Herbert has hacked into an university computer trying to establish a contact with the spirit of illusionist Harry Houdini at the day of the centenary of his birth.

In his device Herbert in order to achieve a quantum entangled state used as a source radioactive thallium, which was controlled by the Geiger radiation counter. The time interval between pulses was chosen as conversion code. Several psychics had participated in the experiments. They tried to influence the endless stream of random anagrams arising from a typewriter or cause “the ghost voice” to be heard out of metaphone. Scientists also have conducted sessions to bring about the “spirit” of a colleague who had recently died, and who knew about this typewriter. In 1985 Herbert wrote a book about metaphysical in physics. In general, his invention and articles quite severely compromised the ideas of quantum communication in the eyes of potential researchers and by the end of the XX century no any substantial progress in this direction was observed.

The Metaphase Sound Machine is an object with 6 rotating disks. Each of the discs is equipped with acoustic sound source (a speaker) and a microphone. Each of the microphones is connected via computer and the rotary axis to the speakers on the disks. Also in the center of installation a Geiger-Mueller counter is set, that detects ionizing radiation in the surrounding area. The intervals between these particles influence rotation velocity of each of the disks. Essentially the object is an audio- and kinetic installation in which a sound is synthesized based on feedbacks, produced by microphones and speakers on rotating discs. Feedback whistles are used as triggers for more complex sound synthesis. Additional harmonic signal processing, as well as the volatility of the dynamic system, lead to the endless variations of sound. The form of the object refers to the generally accepted symbolic notation of quantum entanglement as a biphoton – crossing discs of the orbits.

Osmo

Osmo è un ambiente costituito da una grande sfera (9 metri) gonfiabile in materiale sintetico leggero. Al suo interno è illuminata da raggi laser che simulano le stelle allo scopo di creare un ambiente isolato dall’esterno, apparentemente enorme perché il materiale è una pellicola in parte riflettente.

Ideato da Loop.pH, un laboratorio sperimentale londinese che lavora nell’area del design, dell’architettura e delle scienze che peraltro ha fatto varie installazioni interessanti, come si può vedere qui.

300 speakers, Pianola, vacuum cleaner, audio amplifiers, hard disc recorder, speaker wire, suction hose, piano roll

Notes from author’s site

John Wynne’s untitled installation for 300 speakers, player piano and vacuum cleaner is at once monumental, minimal and immersive. It uses sound and sculptural assemblage to explore and define architectural space and to investigate the borders between sound and music.

The piece has three interwoven sonic elements: the ambient sound of the space in which it is installed, the notes played by the piano, and a computer-controlled soundtrack consisting of synthetic sounds and gently manipulated notes from the piano itself. Because none of these elements are synchronised with each other, the composition will never repeat.

The music punched into the paper roll is Franz Léhar’s 1909 operetta Gypsy Love, but the mechanism has been altered to play at a very slow tempo and the Pianola modified to play only the notes which most excite the resonant frequencies of the gallery space in which it is installed.

Sound moves through the space on trajectories programmed using a 32-channel sound controller, creating a kind of epic, abstract 3-D opera in slow motion. Originally developed at Beaconsfield Gallery, a former Victorian ‘ragged school’ in South London, this piece draws on notions of obsolescence and nostalgia, combining early 20th -century technology and culture with a vast collection of recently discarded hi-fi speakers.

These disparate components are brought together through contemporary digital technology which not only distributes the sound but also controls the (found) vacuum cleaner which in turn drives the Pianola. The piece is site-specific, but it also carries traces of its own history: some of the synthetic sounds were created in response to the light industrial ambience of the work’s original location, some in response to its new site in the Saatchi Gallery. The mountainous formation of speakers, inspired by the recycling plant from which they were rescued, functions both visually and as a platform for the projection of sound, creating, in the words of writer Brandon LaBelle, ‘a soft balance between order and chaos, organization and its rupture’.

Feedback Babies

Un’altra installazione di Darsha Hewitt.

I Fisher-Price Nursery Monitor sono gli antenati (ca. 1983) degli odierni baby monitor con cui si può ascoltare il pargolo a distanza, anche via cellulare. L’ingombrante modello degli anni ’80 era costituito da un trasmettitore e da un ricevitore operanti su frequenze radio. Darsha Hewitt ha trovato un modo di riutilizzare questo dispositivo ormai obsoleto.

The Fisher-Price Nursery Monitor (circa 1983) was a low watt household radio set originally intended to “let parents be in two places at once” by broadcasting the cries of a baby in distress to a mobile receiver accompanying a parent outside of earshot. However, when in very close proximity these devices produce audible feedback that sounds uncannily like whimpering electronic babies. Feedback Babies is an electromechanical sound apparatus that makes use of slow moving motors to automate these transmitters in order to create nuanced feedback patterns.
