Canti delle balene in tempo reale

whalesong.net è un interessante sito la cui “mission” è quella di promuovere la conservazione e la tutela dell’ambiente sottomarino.

In questa ottica, hanno sviluppato il progetto WhaleSong destinato a diffondere in tempo reale, via internet, le voci delle balene e di altri mammiferi marini mediante il sistema schematizzato nella figura qui sotto.

Si tratta, sostanzialmente, di un microfono sottomarino (idrofono) collegato ad un trasmettitore che invia i segnali raccolti dall’idrofono a un ricevitore piazzato sulla costa. Da cui i segnali vengono instradati nella rete grazie ad un server audio e possono essere ascoltati grazie ad una internet radio raggiungibile dal sito di cui sopra o direttamente da questo link.

Fisicamente, il tutto è piazzato sull’isola di Maui, nelle Hawaii, uno dei più importanti siti di whale-watching del globo.

Naturalmente non sempre è possibile contare sulla presenza di vari mammiferi marini nel sito in quanto questi animali compiono lunghe migrazioni. In questo caso la radio trasmette le registrazioni dell’anno precedente.

The Vancouver Soundscape

coverThe World Soundscape Project (WSP) was established as an educational and research group by R. Murray Schafer at Simon Fraser University during the late 1960s and early 1970s. It grew out of Schafer’s initial attempt to draw attention to the sonic environment through a course in noise pollution, as well as from his personal distaste for the more raucous aspects of Vancouver’s rapidly changing soundscape. This work resulted in two small educational booklets, The New Soundscape and The Book of Noise, plus a compendium of Canadian noise bylaws. However, the negative approach that noise pollution inevitably fosters suggested that a more positive approach had to be found, the first attempt being an extended essay by Schafer (in 1973) called ‘The Music of the Environment’, in which he describes examples of acoustic design, good and bad, drawing largely on examples from literature.

Schafer’s call for the establishment of the WSP was answered by a group of highly motivated young composers and students, and, supported by The Donner Canadian Foundation, the group embarked first on a detailed study of the immediate locale, published as The Vancouver Soundscape, and in 1973, on a cross-Canada recording tour by Bruce Davis and Peter Huse, the recordings from which formed the basis of the CBC Ideas radio series Soundscapes of Canada. In 1975, Schafer led a larger group on a European tour that included lectures and workshops in several major cities, and a research project that made detailed investigations of the soundscape of five villages, one in each of Sweden, Germany, Italy, France and Scotland. The tour completed the WSP’s analogue tape library which includes more than 300 tapes recorded in Canada and Europe with a stereo Nagra. The work also produced two publications, a narrative account of the trip called European Sound Diary and a detailed soundscape analysis called Five Village Soundscapes. Schafer’s definitive soundscape text, The Tuning of the World published in 1977 [trad. it. “Il Paesaggio Sonoro”, Ricordi/Unicopli], and Barry Truax’s reference work for acoustic and soundscape terminology, the Handbook for Acoustic Ecology published in 1978, completed the publication phase of the original project.

Ubeboet

coverSearching the old releases from Test Tube, I found this EP by Ubeboet, a sound artist based in Madrid involved in electronic/experimental music since mid 90’s. This work, titled Bleak EP, is dated 2004.

Bleak EP, by Ubeboet, is one of those kind of releases that lives on lasting relationships and on constant reintegration processes, achieving ‘that’ multidimensionality (big word) typical of the acoustic universe, giving so much freedom to the listener, that he (or she) will diminish or amplify the particular singularities of the sound particles that go in and out of the brain.
This work could be very easily integrated into the art of installationism, although never leaving the ‘soundscape’ genre. A constant struggle to arrive (or at least try to) an ideal of ‘musique concrète’. Holding itself to the capturing of sound landscapes, submitting them to a low-frequency treatment, Ubeboet breathes a comforting ‘less is more’ ambient, (re)created and integrated into unhabited sound habitats, or sometimes directly injected into the overcrowded urban territory. Ubeboet rests in the complex world of the ‘anti-fast listening’, where the perception and the raw and naked power of the music are intimately connected. A not-easy, not-clear and not-resolved world, into which we are forced to submerge and seek for the unknown. Highly recommended.

Soundscape

I biologi impegnati nello studio degli ecosistemi dinamici imbottiscono di microfoni una sezione di territorio per ottenere una mappa audio dell’ambient.

Questo procedimento si basa sulle idee del pioniere della bioacustica Bernie Krause, che ha coniato il termine “biophony” e l’ipotesi della nicchia acustica, secondo la quale lo spettro audio di ogni ecosistema è finemente suddiviso fra le specie che lo abitano (ovviamente con l’esclusione dell’uomo che occupa brutalmente tutte le bande).

Si ottengono, così, dei sonogrammi come quelli a destra (click per ingrandire) che vengono poi analizzati per identificare le specie che abitano l’ecosistema.

Venti di Titano

Questa non è una composizione musicale e forse è noiosa, ma ascoltatela.
È il suono registrato dal microfono posto a bordo della sonda Huygens, parte del progetto Cassini di esplorazione dei pianeti esterni, durante la sua discesa di un anno fa su Titano, satellite di Saturno e unica luna del sistema solare con un’atmosfera.
Per quelli che sanno sognare…
