Increased Signal Complexity Improves the Breadth of Generalization in Auditory Perceptual Learning

Figure 1

Conversion of image to sound using The vOICe algorithm. White pixels in the image are represented by a sound with black pixels silent. The elevation of each pixel is coded by frequency with pixels higher in the image having a higher frequency sine wave. All pixels in a vertical raster line are played simultaneously with a 1 second left-to-right horizontal scan across image resulting in the soundscape for the image.
