<Peter B. L. Meijer> is a researcher whose work includes image-to-sound <sensory substitution>. His 1992 engineering paper described how a <grayscale> image could be encoded as a time-varying sound pattern.<An experimental system for auditory image representations by Peter B. L. Meijer>[Image-to-Sound Mapping]{ref}
The design scans image columns from left to right. Horizontal position becomes time within a scan, vertical position selects an audio <frequency>, and brightness sets an oscillator's <amplitude>. For example, a bright point high on the right produces a relatively high-frequency component late in the scan. Different rows contribute superposed tones. This provides an explicit encoding whose mathematical information content can be studied separately from how well a listener learns to interpret it.<An experimental system for auditory image representations by Peter B.
