4-channel spectral improvisation with Joel Cahen and Wajid Yaseen
CHIESA DI SANTA EULALIA (Istituto Cervantes), Via Argenteria Nuova 33, Palermo

These images document an emerging methodology for working with situated sound recordings (a term I prefer to field or environmental recording – perhaps phonograph is preferable). I do not consider these digital files to point backwards in time towards some imagined documentation of a contingency typified by excess. They do present some trace of dynamical spectral activity. Such activity I understand to occur both in the frequency domain and also a mythical, haunted domain of lack, loss and absence.

The spectrograms, while found useful when dealing with many recordings of various duration, are of course an abstraction of the sound itself – they do however present, by this very abstraction, a playful means of re-rendering the recorded sound into something other.

This performance, as part of the Opensound project also suggested to me to explore a means of realtime 4 channel spatialisation using FLOSS tools. This performance was my first live experiment using a mashup of TouchOSC/PD/Ableton to move though an recombinatory 4 channel matrix of the spectral abstractions
