Low-End Device to Convert EEG Waves to MIDI

This research provides a simple and portable system that is able to generate MIDI output based on the inputted data collected through an EEG collecting device. The context is beneficial in many ways, where the therapeutic effects of listening to the music created by the brain waves documents many cases of treating health problems. The approach is influenced by the interface described in the article “Brain-Computer music interface for composition and performance” by Eduardo Reck Miranda, where different frequency bands trigger corresponding piano notes through, and the complexity of the signal represents the tempo of the sound. The correspondence of the sound and the notes has been established through experimental work, where data of participants of a test group where gathered and analyzed, putting intervals for brain frequencies for different notes. The study is an active contribution to the field of the neurofeedback, by providing criteria tools for assessment.
