In Tune
A brainwave-driven radio manipulation to create an auditory form of automatic writing, blending randomness and subconscious interpretation by mapping theta waves to a range of frequencies.
01: A Mind Box
This experiment is inspired by the connection between spiritualism and surrealist automatism. A spirit box scans radio frequencies rapidly, producing white noise interspersed with fragmented audio signals. Users interpret these sounds as meaningful messages, influenced by pareidolia, the human tendency to perceive patterns in randomness.
The experiment explores how theta waves, associated with creativity and subconscious states, can modulate radio frequencies to produce an auditory form of automatic writing. Radios transform electromagnetic waves into sound using tuners, demodulators, and amplifiers, paralleling how EEG systems convert brain activity into data.
This similarity reinforces the conceptual link between brain signals and radio waves. Radios’ inherent unpredictability and the Surrealists’ fascination with chance further connect the two, enabling the project to externalize subconscious signals by mapping theta wave activity to dynamic radio frequency changes.
02: Troubleshooting and Refinement
During the making process, two key issues emerged. The first was the radio module’s low audio output, which remained too quiet despite amplification. This was traced to insufficient power for high-impedance speakers. Switching to earphones resolved the problem, delivering clearer audio and fostering a more personal listening experience aligned with the project’s focus on subconscious engagement.
The second issue was the disruptive noise during radio frequency changes, caused by frequent EEG data updates. For this, a two-second delay was introduced in the data processing, smoothing transitions while maintaining responsiveness. These solutions not only overcame technical obstacles but also enhanced the system's ability to accurately reflect brainwave activity, ensuring a cohesive and engaging auditory output.
