As with any exhibited art work, the creator cannot know how the viewer will perceive and experience the work, no matter the intention. Looking back at the installation LCD as exhibited and interacted with by the spectator, the following aspects are brought to our attention.

-Implementing stereo pair to reveal the tonality of the overall soundscape (background and individual fans)

-Introducing flashing light sources to accentuate the detailed changes in the sound

-Lower overall sound level

-Altered arrangement of separate modules in order for the ‘audience’ to interact through being able to see each other

-Stronger emphasis on the relationships between each specific sound and its’ visual source

-The creators to perform with the installation to amplify its’ diversity in sound and to bridge the relationship between audience and interactiveness

Optical / Audio Explorations:

Supervisor: Dr Sean Williams


An exploration into the lightscape of the contempory urban environment, where transient aspects of the urban lightscape were examined, recorded and translated into an audio format to make the variations perceptable to the observer’s senses.


LCD is a sound installation that amplifies this secret world of light and manifests it as a material that can be directly manipulated and interacted with.


Informed by the work of early experimenters with Optical Audio such as Daphne Oram, Oscar Fischinger and others. LCD uses specially designed optical circuits and repurposed computer parts as components in an array of six sound sculptures that emit electronic tones when activated by LED torches.


The interactive element It’s self comprises two elements, firstly we utilise handheld led torches to stimulate a series of electro-mechanical oscillators to manufacture base tones. we utilize a second LED light source to modify the tone by sonic granulation and pitch shifting   by means of  MaxDSP via an Arduino processing to create a rich and pervasive sound world that is determined by user interaction.


Secondly, the data from background and transient light level variations was intergrated to form an audio composition that forms the background to the installation, representing the urban landscape, over which we lay interactive elements to represent the way in which people influence their environment.


The interactive element is laid on top of the background composition to reflect the complexity of the modern urban lightscape.

booklet inspiration?

I found this the other day – it’s not the recording circuit we used but a nice explanation, might be good for some ideas for the booklet/write up we’re handing out at ECA? It’s from Forrest Mims’ Mini-Engineer’s Notebook: Science Projects (1990) –


Hey! I know the installation is almost finished, but I thought I could share this video showing an interface with 24 light sensitive sensors…. Towards the end (around 03:00) the values of the sensors work the opposite way (where less light equals more sounds)!
