Sonification of focalcheck beads

This movie shows multichannel image volumes of beads 1,2, and 3 alongside one another, each overlaid with a false color image. While the false color renderings of each volume appear to be the same visually, the sonification of each volume enunciates the subtle spectral difference between beads 1 and 2, and the spectral difference between the core and the edge in bead 3.
