light exposure tests


is an audible experiment which deals with the topics of modulation, distortion, noise and objects. Basic motivation was to manipulate ordinary objects such as windows, doors or tables and transforming them into speakers.

The preoccupation with this topic is much more theoretical then practical. Therefore I conducted a couple of experiments, analyses and two small projects dealing with the results of my research.

Modulation by audible series connection

The first part of the research included analyzing the modulation of a particular sound sample which was played back through an object and recorded at the same time. This recording was send to the next speaker-object and outputted again. After six iterations of playback and recording the different steps of the modulation were compared based on the audible spectrum and the waveform of each phase.

Modulation by audible series connection with constant delay

Due to the results of the previous analyses an installation for various synthesizers and musical instruments were set up. All signals were send through a row of 6 mechanical vibration speakers attached to an acrylic plate in front of a monitor. Using a constant delay of 3 seconds between recording and playback the musicians were able to play one note which was effectively delayed for 18 seconds before being played on the last speaker. Thereby various sound patterns emerged.

In connection to the outputted sounds, the video signal shown on the screens started to warp. Each monitor represents an instance of the audible spectrum in which they are able to oscillate.

Modulation by audible series connection with an alterable delay

In addition to the installation which utilized a constant delay, an object were one can set the delay by changing the distance between the output devices were conceptualized. A simple drum kick or other sample - even a tap on the wooden plate - can be used as the seed of sound. By changing the distance between the objects, the delay varies. A playful instrument comes into being.
