Call for Proposals – Sound Installations in Favignana
Call for Proposals – Sound Installations in Ex Stabilimento Florio della Tonnare di Favignana e Formica
Favignana Island Italy
AntiTesi in collaboration with the Superintendence for Cultural and Environmental Heritage of Trapani,, is announcing a Call for Proposals for Sound installations to present at Ex Stabilimento Florio delle Tonnare di Favignana e Formica in Favignana island.
This call is connected to the Eighth edition of the Live!IXem festivals of music, sound and electronic arts.
The aim is to highlight the works of those artists who, involved in an experimental and creative exploration, use sound, integrating it with electronic audio-visual and digital design for Art installations in specific sites.
Another aim is to witness the new aesthetic in contemporary art through a new way to conceive and carry out works within (or outside) of architectural spaces.
In this regard, the spaces that will host this could not be more appropriate: the former Florio Tuna factory on the island of Favignana in Sicily, the largest of the Mediterranean, which takes its name from a family of entrepreneurs that at the beginning of the twentieth century was the great protagonist in Sicily, the Belle Epoque. The ancient structure located in the largest of the Egadi islands, were obtained after the recent restoration of museum space, a conference room with 400 seats and a guest room.
To make this call even stronger there will be a collaboration between Live!iXem and OpenSound a platform that brings together seven European partners to create a project for cooperation and exchange that puts the sound in the middle of a series of outreach and artistic initiatives.
Open Sound is in fact a Grundtvig project for mobility and partnership in the training supported by the EU through through the agency LLP – Life Long Learning Programme. Thanks to this partnership, Sicily will be the first venue where the festival will converge with some of the major representatives linked to the European art scene and musical sound research. During the festival, workshops will be conducted by some of the guest artists (the access to workshops is free of charge): this will contribute to become familiar with the locations of the former Florio Tuna factory on the island of Favignana.
SUBMISSIONS
We encourage proposals for site specific Sound Installations that will have to be set up in one of the locations of the Ex Stabilimento Florio della Tonnare di Favignana e Formica in Favignana Island Italy. Subscription and participation to the call are free of charge. It will be necessary to explore the locations through specific preparatory visits during Live!iXem Festival 2011, from 8 to 11 december 2011.
Suggested topics for presentations include, but are not limited to:
- Best practices in Sound and architecture
- Techniques used for Sound/Art Installation
- Sound and environment/Sound ecology
- Site specific
- Software & network management
- History & aesthetic theory of Sound Art/Installation
- Teaching & pedagogical strategies
- Hardware (audio, interface, computers, loudspeakers)
- Software environments & frameworks
- Artists/Composers’ perspectives on their own works
For more information and instructions for submissions, please refer to the website, or download Call in PDF in english or PDF in italian
Email contact: info@antitesi.org
The deadline for submission is February 26, 2012, but preliminary and preparatory visits will take place btw 8-11 dec 2011.
Wolfram
Wolfram’s sites offer a lot of resources about mathematics.
Founded by Stephen Wolfram in 1987, Wolfram Research is one of the world’s most respected software companies—as well as a powerhouse of scientific and technical innovation. As pioneers in computational science and the computational paradigm, we have pursued a long-term vision to develop the science, technology, and tools to make computation an ever-more-potent force in today’s and tomorrow’s world.
Their software Mathematica, not for free, allows to compute data to create interactive demonstrations; look at some examples here.
There is the possibility to examine for free a lot of their applications downloading and installing their player, unfortunately for Windows only, after that it is enough you visit the demonstrations page, browse a topic – e.g. Physical Sciences …
… and choose a subtopic, e.g. Physics and then Acoustics …
Now you can try about some demonstrations; here some examples from wolframmathematica youtube channel:
and others from the subtopic Physical Sciences/Physics/Waves:
Obviously you can try a lot of interactive demonstrations by tags, … sounds, audio, harmonics, … so:
- download and install the player
- choose an interactive demonstration
- enjoy
Again, at wolframalpha.com/widgets you can try or create widgets for your site/blog.
An emotion detector for baby
An interesting project by a japanese team. It could be possible to codify and to interpret the emotional state of babies analyzing power spectrum and pitch of their crying.
from cacm.acm.org
From eurekalert:
Baby monitors of the future could translate infant cries, so that parents will know for certain whether their child is sleepy, hungry, needing a change, or in pain. Japanese scientists report details of a statistical computer program that can analyze a baby’s crying in the International Journal of Biometrics.
As any new parent knows, babies have a very loud method of revealing their emotional state – crying. Unfortunately, the parenting handbook does not offer guidance on how to determine what the crying means. Parents sometimes learn with experience that their child’s cries may be slightly different depending on their cause, whether hunger or discomfort… (more…)

The Art of Soundscaping
Sound Installations + Workshop
25-27 September 2009, Palermo
[English version at bottom]
Antitesi ospita spesso artisti di passaggio per mettere in contatto il pubblico ed i creativi locali con artisti provenienti da tutto il mondo.
Il prossimo evento sarà dedicato all’Arte Sonora (Sound Art) attraverso un fitto calendario, dal 25 al 27 settembre 2009: installazioni sonore degli artisti Andrea Valle (I) e Peter Klingt (AT) e il workshop ‘The Art of Soundscaping’.
Il Workshop sarà condotto dall’ austriaco Klingt, si tratta di un corso-laboratorio intensivo dedicato alla tecnica ed all’arte di utilizzare registrazioni sonore di ambienti e di suoni naturali per riorganizzarli in veri e propri paesaggi sonori ricchi di suggestioni e sollecitazioni uditive. Di seguito il dettaglio:
Harmonics or Overtones?
Look at this:
It is 1 second of pink-noise. A the top you can see the waveform, at the bottom a very confusional image, its spectrogram.
Now look at this:
Free or Open Source audio/software – up-to-date
Nice applications for sound analysis from UCL.
from UCL: SFSystem
They are like many other applications, but some of them can offer to you many little surprises.
For vocal analysis I suggest:
SFS – Speech Filing System Tools for Speech Research
RTSPECT – Real-time Waveform and Spectrum Display
ESYNTH – Harmonic analysis/synthesis teaching tool
ESECTION – Speech signal cross-sections
ESYSTEM – Signals and Systems teaching tool
VTDEMO – Articulatory synthesis teaching tool
~~~~~
Visiting many sites and blogs, I have discovered many software.
Here a little link list – click pictures to enlarge:
Audacity – It is free, open source software for recording and editing sounds with the possibility to load VST effects. For win, mac and linux.
Baudline – It is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail. Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters. The baudline signal analyzer combines fast digital signal processing, versatile high speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.
Excellent, for linux.
Madde – An additive, real-time, singing synthesiser by the great Svante Granqvist. We can create artificial vocal sounds and vowels manipulating overtones and formants. It’s fantastic.
If you want look at my Madde video in my left sidebar.
Overtone Analyzer – thanks Maass and Saus, we all know it! It is in beta version now, but in the future we’ll must pay for it.
Praat – It is a program for speech analysis and synthesis written by Paul Boersma and David Weenink at the Department of Phonetics of the University of Amsterdam.
It is a research, publication, and productivity tool for phoneticians, for linux, mac, win.
Pure Data – Like Max/MSP, Pd is a “patcher” programming language, but Open Source. It is a real-time graphical programming environment for audio, video, and graphical processing. It is the third major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, jMax, etc.) originally developed by Miller Puckette and company at IRCAM.
Pd was created to explore ideas of how to further refine the Max paradigm with the core ideas of allowing data to be treated in a more open-ended way and opening it up to applications outside of audio and MIDI, such as graphics and video.
For linux, mac and win.
Raven Lite – It is a free software program that lets users record, save, and visualize sounds as spectrograms and waveforms. Raven Lite is intended for students, educators, and hobbyists, and can be used for learning about sounds, as an aid in birdsong recognition, and in musical instruction.
For win and mac.
Snd – complete sound editor. It currently runs on nearly all Unix-based systems, including Mac OSX and Cygwin. It might even run on others if the GUI support is omitted. It allows 3D sonograms.
Sonic Visualiser – The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.
As well as a number of features designed to make exploring audio data as revealing and fun as possible, Sonic Visualiser also has powerful annotation capabilities to help you to describe what you find, and the ability to run automated annotation and analysis plugins in the Vamp analysis plugin format – as well as applying standard audio effects.
Sonic Visualiser will be of particular interest to musicologists, archivists, signal-processing researchers and anyone else looking for a friendly way to take a look at what lies inside the audio file.for linux, OS/X, and win.
Sonogram Visible Speech – Sonogram has been programmed at the German Research Center for Artificial Intelligence (Deutsches Forschungszentrum fuer Kuenstliche Intelligenz DFKI, www.dfki.de), and is a 3D tool (it needs Java3D) to analyze speech and sound signals with FFT.
For win, mac and linux.
To download Java 3D you click here and select your platform.
Speech Tools – You can use Speech Analyzer to do the following tasks:
perform fundamental frequency, spectrographic and spectral analysis, and duration measurements, add phonemic, orthographic, tone, and gloss transcriptions to phonetic transcriptions in an interlinear format, perform ethnomusicological analysis of music recordings, use slowed playback, repeat loops and overlays to assist with perception and mimicry of sounds for language learning.
It is very useful to formants analysis.
I think only for win.
Visual Analyser – It is a complete professional real time software, transform your PC in a complete set of instruments; no new hardware necessary (you can use the Sound Card of your PC) or you can use a specific external hardware.
Only for win.
ZynAddSubFX – It is a open source software synthesizer capable of making a countless number of instruments, from some common heared from expensive hardware to interesting sounds that you’ll boost to an amazing universe of sounds.
An incredible synth software (not only), for win and linux.
Wave Editor – Fast and easy digital audio editing software for Windows. It provides powerful and user-friendly editing environment which suits beginners especially and perform basic editing capabilities like: cut, copy, paste and delete parts of recording.
Wave Surfer – It is an Open Source tool for sound visualization and manipulation. It has been designed to suit both novice and advanced users. WaveSurfer has a simple and logical user interface that provides functionality in an intuitive way and which can be adapted to different tasks. It can be used as a stand-alone tool for a wide range of tasks in speech research and education. Typical applications are speech/sound analysis and sound annotation/transcription. WaveSurfer can also serve as a platform for more advanced/specialized applications. This is accomplished either through extending the WaveSurfer application with new custom plug-ins or by embedding WaveSurfer visualization components in other applications.
For win, linux, and mac.
To finish, at the moment, this is a great list of free virtual synthesizers, VST, sequencers, emulations, … but perhaps all for win, but I am sure that some works on mac and linux too:

Hobnox Audiotool
Hobnox è una beta piattaforma web per la creazione e condivisione di progetti multimediali.
Ma vorrei segnalarvi al suo interno la divertente applicazione Audiotool, la quale permette di divertirsi con il collegamento tra vari moduli audio per la realizzazione di strutture audio/ritmiche, anche se a mio avviso un pò troppo techno, e nulla a che vedere con Max/MSP.
Praticamente tramite flash si possono creare delle patch utilizzando elementi forniti in dotazione, e collegandoli a piacere in funzione degli obiettivi.
Avrete a disposizione: (more…)
diapason 432 Hz
Da qualche anno si legge in rete di questa Rivoluzione Omega. A prescindere che non condivido molto il termine rivoluzione, devo dire che condivido pienamente l’obiettivo di riportare (leggi qui) il diapason a 432 Hz.
La Rivoluzione Omega parte da osservazioni di tale Ananda Bosman, riunite in seguito in un testo che troviamo tradotto in italiano … (more…)

Thanks to my friend Jens Mugge, this is another roll of:
Sonic boom
From Wikipedia:
The term sonic boom is commonly used to refer to the shocks caused by the supersonic flight of an aircraft. Sonic booms generate enormous amounts of sound energy, sounding much like an explosion. Thunder is a type of natural sonic boom, created by the rapid heating and expansion of air in a lightning discharge. (more…)

On YouTube you can find a nice roll about this effect:
Vocal Resonance in Pisa’s baptistry
I love very long reverbs.
Sounds natural
I report an interesting post by [klang~440]
…
Another place for listening to gravity is the desert: in some deserts and dunes, there’s a phenomenon called ‘booming sands’. Due to the special characteristics of some kinds of sand (extremely round shape, well polished and covered with certain minerals), it makes sounds, ranging from squeaking when you walk on it to actual low frequency booming when the sand is shifted by gravity. There’s a wonderful movie on Youtube:
Overtone Analyzer free version
The free version of this software is ready for you.
Overtone Analyzer is a software for vocal and sound analysis, in particular addressed to overtone singers.
It is very important to understand that this version has got less features than the full version, and I show them:
- record sounds and render high quality spectrogram and spectrum displays in real time
- interactive real-time adjustments of display parameters
- overtone slider overlay = 1
- integrated colormap editor
- longest displayed time range = 10 seconds continuous loop
- best supported frequency resolution = 10.8 Hz at 22 kHz
- best supported sampling rate = 22 kHz
- best supported bit depth = 16 bit
- audio quality = mp3 quality
These few features can limit our work, but they can be useful to know about Overtone Analyzer, for free.

Team records ‘music’ from stars
HD49933 was one of the stars observed using the Corot telescope
Thanks to Riccardo.
By Pallab Ghosh
Science correspondent, BBC NewsScientists have recorded the sound of three stars similar to our Sun using France’s Corot space telescope.
A team writing in Science journal says the sounds have enabled them to get information about processes deep within stars for the first time.
If you listen closely to the sounds of each star – by clicking on the media in this page – you’ll hear a regular repeating pattern.
Sentimental Journey
Great music and sounds by Roberto Laneri, international guru about Overtone Singing & Co.. It is a very particular CD, we can listen didjeridoo, overtone singing, indian and oriental instruments, all the clarinet-sax category and audio processing. It is interesting the capability of Laneri to mix different instruments and musical genres without defined marks, without irritations. This is a great quality for a real musician, and this is my opinion.
The author says:
Sentimental Journey is the first american song I heard (I must have been 8 or so) … My uncle played for me on a 78 rpm disc, it was sung by Doris Day … To me it was a revelation, I thought I was listening to the quintessence of American music. Was it jazz? Blues? … was sure that song incarnated the perfection of all those genres … Decades later (…) I can still recall the impression that song had to me, like a key opening up all sorts of musical treasures, the start of a journey which has continued to all sorts of music from all lands and times …
I suggest for you:
Sentimental Journey
The Landing
Pangea
mp3 from youtube video
I suggest two online services. They are very simple.
On vmeste.fr you must insert the URL of a youtube video (or other), click on Extract, wait for some seconds, click on “Download it here”, and choose the destination folder. Sometimes the site is down.
On vixy.net you have five options, you must insert the URL, click on Start, wait for few seconds, and decide to open or save the file.
Obviously the youtube audio file is in low quality mp3 format.
vmeste.fr
vixy.net
Vi propongo due semplici servizi online.
Con vmeste.fr è sufficiente inserire l’indirizzo del file video youtube, cliccare su Extract, poi su “Download it here”, e per finire scegliere la destinazione. Attenzione che il sito talvolta è down.
Vixy.net è analogo al precedente, ma ci permette di scegliere tra cinque possibilità (vedi figura). Basta inserire l’indirizzo del video, cliccare su Start, attendere qualche secondo per poi decidere se aprire o salvare il file.
Ovviamente i file audio estratti da youtube sono mp3 a basso bitrate.
Concert for Bats
Mariolina Zitta created this audio cd using bat calls and other sounds, voice, logs with sticks, overtone singing, tibetan bowls and didjeridoo (Lorenzo Pierobon), steps through the cave, mouth bow, seed rattle, shingle, …
Frequency of bat calls was reduced to be part of our human hearing range.
Concert fo Bats lives on sound streams running through the evanescent state of mind that exists in the borderland between consciousness and dream, where syntax is taken apart, and the images of thought fade away, uncontrolled. There, sudden visions and peaceful wandering come to life in our preconscious spaces, and we drift out to the pure moment of the psyche. The fusion of inaudible night sounds and fragments of voices, of matter and electronic waves, keeps our soul suspended in the arrhythmia of the Eternal Return, and brings about an ancestral enchantment, a possible echo of the lost feeling of original Man.
Mariolina Zitta: Concert for Bats, track 4:
Mariolina Zitta, musicista e speleologa, propone questo Concerto per pipistrelli, voci e suoni naturali, realizzato prelevando campioni audio di bat calls e miscelandoli opportunamente con sonorità di canto armonico, tibetan bowls e didjeridoo (Lorenzo Pierobon), e altre provenienti da stalattiti, pietre sonore, legni, conchiglia tromba, arco a bocca, …
In alcuni casi la frequenza del suono dei bats è stata ridotta per rientrare nel nostro range uditivo.
Concert for bats vive di flussi sonori che percorrono quello stato evanescente della mente ai confini tra coscienza e sogno, dove si destrutturano le sintassi ed evaporano incontrollate le immagini del pensiero. E’ lì che si accendono improvvise visioni e placidi nomadismi negli spazi preconsci, che ci si abbandona all’istante puro della psiche, a libere evoluzioni, senza gravità o punti di fuga.
La fusione di inudibili suoni notturni e frammenti di voci, materia e onde elettroniche sospende l’anima nell’aritmìa dell’Eterno Ritorno e genera un atavico incantamento, eco forse del sentire perduto dell’Uomo delle origini.
0522.RE
Patrizio Ligabue – didjeridoo e overtone singing – e Simone Copellini – tromba, synth, guitars, guitar bass, programmer – hanno sfornato questo particolare cd.
Me l’ha consegnato lo stesso Patrizio al termine di un seminario. Devo dire che personalmente non trovo molto interessante la miscela composta da didje-overtone singing e funk & Co., in ogni caso l’audio è di ottimo livello.
Vi propongo l’unico brano che mi ha colpito, Luci Notturne, composto ed eseguito dall’ottimo Ligabue stesso, per didje e voce.
Per chi volesse ascoltare il tutto, ecco il link.
Livid Looper
Thanks to Seralf I have tried Livid Looper, an open source software (Mac and Win) for real time looping, designed in Max/MSP 5 visual programming environment. It allows to create and to manage at most 6 loops, using audio file or recording in real time, MIDI controller and OSC devices. It means that people can play with multiple computers on separate interfaces controlling a single server computer, so it is possible to create a computer music band.
Each loop module shows many controllers, a multi-filter bank, delay, pan, pitch and so on, but the most interesting are a Ring Modulator, a Grain, a Degrade, an Envelope and the VST plugin downloading.
I don’t use loop in real time, so I need more time to understand all the functions of this software, but it is very pleasant. A little problem for me can be the fiked size of each module, what a pity!
Seralf mi ha segnalato Livid Looper, un software open source per Mac e Win scritto in Max/MSP 5, specifico per la creazione e gestione di loop in real time, interoperabile via MIDI e OSC, per cui diventa possibile interfacciarsi con altri computers e creare una computer music band.
E’ possibile creare fino a 6 loop, sia utilizzando audio file dal proprio HD sia registrando in tempo reale, e forse questa è la particolarità. Ciascun loop module prevede vari controlli, tra cui, oltre al “solito” banco di filtri e delay, un Ring Modulator, un Grain, un Degrade, un pregevole ADSR (envelope) e la possibilità di caricare VST.
Sinceramente, per uno come me che non utilizza loop in real time e anzi non lavora in real time tutto ciò non risulta di immediata comprensione, ad esempio devo ancora capire come caricare i VST, sicuramente ci vorrà un bel pò di tempo. Comunque è molto divertente.
L’interfaccia esteticamente piacevole presenta per me il difetto di staticità dei moduli, di dimensione prefissata e immutabile.
