The objects, systems and proposals detailed below respond to a strategy to relate bodies with the sonic and vibrational experience. To develop a specific architecture, as well as a wide range of tools, starting from very simple resources until reaching designs more complex ones. All devices are accompanied by a guide that allows their reproduction. The mediators created the electronic devices specifically for INFRA. Their function is to generate an infrasonic spectrum in which the experiences are sustained. Together with the participants, different devices were made, that emphasize different sensory experiences. The intention is that these devices can be replicated and implemented on various occasions, so that a greater number of deaf people benefit from the research.
Electronic modules:
INFRA Wavegenerator
Audio wave generator
The INFRA Wavegenerator module is a voltage controlled monophonic sound source. Most of the timbres are complex in nature, covering a modular analog setup that would require a full box of oscillators, filters, VCAs, waveformers, and ring modulators. It contains sophisticated digital synthesis algorithms, where each algorithm is controlled by two continuously variable parameters under the timbre and color controls, both voltage controllable. The meta-parameters that pass through the key points simultaneously affect several dimensions of the timbre, creating complex movements that would be difficult to generate with a traditional modular configuration.
INFRA 4Polegen
Control wave generator
The INFRA 4Polegen module and its firmware open up new paths for wave control understood as a polymorphic module, where a generic set of inputs and outputs. Its OLED screen allows mapping these inputs and outputs for each application and has four channels within each application. The design of the module is modifiable and adaptable under the parameters of the interface or the modification of firmware.
