Lost Oscillations: Exploring a City’s Space and Time With an Interactive Auditory Art Installation

Presented at the 22nd International Conference on Auditory Display (ICAD-2016)Lost Oscillations is a spatio-temporal sound art installation that allows users to explore the past and present of a city's soundscape. Participants are positioned in the center of an octophonic speaker array; situated in the middle of the array is a touch-sensitive user interface. The user interface is a stylized representation of a map of Christchurch, New Zealand, with electrodes placed throughout the map. Upon touching an electrode, one of many sound recordings made at the electrode's real-world location is chosen and played; users must stay in contact with the electrodes in order for the sounds to continue playing, requiring commitment from users in order to explore the soundscape. The sound recordings have been chosen to represent Christchurch's development throughout its history, allowing participants to explore the evolution of the city from the early 20th Century through to its post-earthquake reconstruction. This paper discusses the motivations for Lost Oscillations before presenting the installation's design, development, and presentation

Channelisation of Noise through a Rhythmic Grid: Brutalist Mechatronic Sound-sculpture

The aim of this thesis is to provide accessibility and appreciation for sounds that are conventionally perceived as non-musical or “noise”. Ordering the noise on a grid of metric rhythms, and underlining its materiality through an audiovisual mode of expression are the two main strategies employed. Using the medium of mechatronics, mechanically generated sonic by-products of technological developments are chosen as the focus sonic material. As a result, the output of this research extends what is known as glitch music outside the territory of amplified sound, to a realm where noise is created physically and acoustically. Based on these objectives, and following an investigation on the use of mechatronics in contemporary sound-based art, an ensemble of mechatronic sound-sculptures is designed and developed. Varying in terms of material, sound-generating mechanism, and sonic quality, the ensemble is divided into three different instrument-types, each of which is introduced, thoroughly described, and sonically evaluated. Next, three new audiovisual works are developed and realised utilising the mechatronic sound-sculptures, in order to turn into practice the ideas explored in this research. These compositions – which are all exhibited in competitive international symposiums – undertake the integration of mechatronics in three areas of sonic arts that are interconnected with the sound-sculptures. Furthermore, this thesis also establishes an aesthetic framework that formalises a significant body of contemporary sound art and music that, prior to this work, had suffered academic inattention. Probing the various parallels between the ideas developed in this thesis and Brutalist architecture, ‘sound-based brutalism’ is coined and formulated as an aesthetic underpinning for not only the academically marginalised works discussed, but also the work of the author. Lastly, two audiovisual projects (a performance and a series of ten installation pieces) are developed using the entire mechatronic sound-sculpture series in an effort to realise ‘sound-based brutalism’

An Inclusive Musical Mechatronics Course

This paper presents the design of a novel course in mechatronics, based on a project-based learning pedagogical philosophy that uses music as the theme to introduce to a diverse range of learners, the essential concepts of mechatronic practice. The course is designed at a post-graduate level and is targeted at international students who are likely to have a diverse range of background knowledge and potentially even a greater diversity in practical experience. The course builds upon our knowledge and capability in the construction or instrumentation of musical devices and cumulates in the design of a new mechatronic chordophone and the preparation of an IEEE conference paper submission

Complex: Physical Re-sonification of Urban Noise

Presented at the 20th International Conference on Auditory Display (ICAD2014), June 22-25, 2014, New York, NY.This paper explores the aesthetic and social values of the noises of modern urban soundscapes and discusses some strategies for boosting the accessibility and appreciation of works of sound art and experimental music that employ them. A proposed audiovisual installation––entitled complex––is outlined as a practical application of techniques designed to reveal the sonic aesthetics of urban technological noise, primarily through resonification and visualization. This will be achieved sonically and physically, by mapping sonic data collected from New York City soundscape (using the Citygram project) onto custom-designed mechatronic soundsculptures

Click::RAND. A Minimalist Sound Sculpture

Discovering outmoded or obsolete technologies and appropriating them in creative practice can uncover new relationships between those technologies. Using a media archaeological research approach, this paper presents the electromechanical relay and a book of random numbers as related forms of obsolete media. Situated within the context of electromechanical sound art, the work uses a non-deterministic approach to explore the non-linear and unpredictable agency and materiality of the objects in the work. Developed by the first author, Click::RAND is an object-based sound installation. The work has been developed as an audio- visual representation of a genealogy of connections between these two forms of media in the history of computing
