Exploring 3D audio for brain sonification
MetadataShow full item record
Brain activity data, measured by functional Magnetic Resonance Imaging (fMRI), produces extremely high dimensional, sparse and noisy signals which are difficult to visualize, monitor and analyze. The use of spatial music can be particularly appropriate to represent its contained patterns. The literature describes several research done on sonifying neuroimaging data as well as different techniques to use spatialization as a musical language. In this paper, we discuss an artistic approach to fMRI sonification exploiting new compositional paradigms in spatial music. There fore, we have consider the brain activity as audio base material of a the spatial musical composition. Our approach attempts to explore the aesthetic potential of brain sonification not by transforming the data beyond the recognizable, and presenting the data as direct as possible.
