| Spectromatic is a program for generating spectrograms from audio |
| files. Spectrograms are a form of simple time-frequency analysis which |
| lets you see how the distribution of energy at different frequencies |
| in an audio stream change over time. For example, if you play a scale |
| on a musical instrument, you will see a climbing and/or descending |
| pattern of blobs as you move from left to right. |
| Spectromatic reads its input as mono or stereo 16-bit wave files, and |
| writes the output image to an elongated PNG image (colour for stereo, |
| grayscale for mono audio). |
