plangent/perdu is a real-time Pd composition inspired by the spatial possibilities afforded by WFS. There is one source sound created with the z12 algorithm (see Puckette 2015, SEAMUS) premiered in the work Cubic Zirconia (2014). However, this sound is “invisible” throughout the majority of the piece. Instead, it is the source for 8 different resonators, all different processes that can only make sound as a consequence of an input source. At first, we hear the source sound exposed. But it soon disappears, and all we hear are the resonators responding to an unheard influence.
In my previous works, I aimed to create an immersive experience of frenetic but incoherent motion around the listener. However, WFS permits sound to move through or next to the listener. So this piece explores placing sounds in various points of space, still or moving.
Later, I needed to translate plangent/perdu for the 124 speaker system at the Cube at Virginia Tech. Both the technology and aspects of the spatial aesthetics had to change. This 8-channel version is a re-spatialized version of the Cube performance, recorded to fixed media.
The title comes from the concept of the work: plangent, English for resonant or ringing, and perdu, originally a French word meaning lost that was absorbed into English and changed to mean hidden.
Kerry is a composer and researcher working in both acoustic and computer media. She develops real-time methods for spatialization and stochastic algorithms for musical practice. Her work endeavours to achieve aesthetic and philosophical aims while taking inspiration from mathematical and natural processes. In this way, each work combines art with science and technology from various domains. Her works have been performed in Asia, Australia, Europe and North America.
As a researcher, Kerry's interests include real-time algorithmic methods for music composition and sound synthesis, spatialization techniques for 3D sounds and electronic/electroacoustic musicology. Her research has been presented in international conferences around the world.
In 2010, Kerry led a group of practitioners to form the Irish Sound, Science and Technology Association, where she served as President until 2015.
Currently, Kerry is a Lecturer at the University of Limerick in the Digital Media and Arts Research Centre. She is the Principal Investigator for the Spatialization and Auditory Display Environment (SpADE).
