This is a sampler of the "VoxAura, the River Sings" project which is part of "Turku is Listening" a series curated and produced by Simo and Tuike Alitalo during Turku 2011 EuropeanCapital of Culture.
The project consists of two vessels, moored either side of Turku's Theatre Bridge, equipped with speakers which broadcast a soundscape. The first of these plays material from a large archive of sound recordings which evoke the maritime traditions and marine environment of the Baltic; whilst the second transforms this material, allowing us to 'listen' to water quality data that is constantly collected by two trans-Baltic ferries and downloaded to the the work.
The project's computer system takes variables from this data, such as position, depth, temperature, salinity, turbidity and pH, using them as musical parameters to transform the source audio (which is playing simultaneously on the first vessel) producing an ethereal 'datamusic" as a metaphor for, or analogue of the chemical composition of the sea.

VoxAura 2 - Jon Drummond & Nigel Helyer

VoxAura 1 - Jon Drummond & Nigel Helyer

Live performance of Pattern Recognition, an interactive composition/performance; its identity can be considered equally in terms instrument, composition and improvisation. Composition in part becomes instrument design - mapping interfaces to sound generating parameters, but also designing algorithmic process and points of sonic potential to be realised through performance. Performed at Chronology Arts Electric ID March 2009.

The golden ratio, the golden section, the golden mean, the divine proportion has long fascinated artists, architects, numerologists and mathematicians. Its links with the Fibonacci numbers (1, 1, 2, 3, 5, 8, 13…) further connects with forms found in the natural world and the archetypal golden spiral. In this performance the cello sound (timbre) is analysed in real-time and reproduced spectrally, replacing the expected harmonic series, with values derived from the golden ratio. Thus the work exists as an interplay between the natural harmonic series of the cello's strings, and the computer's reinterpreted golden mean spectral space. For further explorations see György Doczi (1981/2005), The Power of Limits: Proportional Harmonies in Nature, Art, and Architecture.

Jon Borwein, & Francisco Javier Aragón Artacho – Visualisation
Jon Drummond – Sonification
A Random Walk Through π 
Jon Borwein's and Francisco Javier Aragón Artacho's astonishing visualisation of π (http://gigapan.com/gigapans/106803) is a random walk made out of the first 100 billion digits of π in base 4 with the following rules for the steps: 0 right, 1 up, 2 left, 3 down. The research addresses such questions as to whether (and why) numbers such as π and e are “normal" and applications for visualising other large number sets. Sonifying this data presented unique challenges, not the least of which was the huge size of the data set! Three approaches are presented here, each 3.14… minutes long. The three sonifications take different approaches to interpreting the data - texture and timbre, rhythm and pulse, pitch and duration. For further explorations see http://www.carma.newcastle.edu.au/jon.
