Turn images into sounds viewable on a spectrogram!
The idea isn't that new—Aphex Twin did this in 1999, and people have been doing it manually with whistle/voice since at least 2009.
This program is written using Processing and depends on the processing-sound library, which you will need to install before running.
For visualizations, I played sounds through my PC speakers and used the Spectroid Android app.

| Parameter | Description |
|---|---|
timeDelta |
Milliseconds to spend on each column of the image; scales the image horizontally |
resolution |
Number of vertical "pixels" the image should have. Higher values tend to have more noise |
logFreqStart |
Lower bound, as a power of 10, of the frequency the program can emit |
logFreqEnd |
Upper bound of the frequency |
Note that this is built with a log-scaled spectrogram in mind. If yours is linearly scaled, then edit this line to accommodate your needs.
