- Transforming EEG Seizure Data into Music: A Coding Journey

In this video, I explore the fascinating process of converting EEG data into music. I start by examining a recording with seizures, aiming to transform these EEG patterns into musical notes. Throughout the video, I encounter various challenges, such as issues with function compatibility, data extraction, and audio context errors. My focus is on extracting different frequency bands from the EEG and mapping them into musical notes, considering the specific features of the data, especially the seizure components. I delve into JavaScript coding, troubleshooting, and testing different functions to achieve the desired musical output. The video is a real-time demonstration of problem-solving and coding in action, as I work through errors and experiment with different solutions to create a unique EEG-based musical experience.
