## About
SpectrumPrinter converts images or messages to audio signals, which can be viewed using spectrograms (with [Audacity](http://audacity.sourceforge.net/) or [SpectrumView](https://itunes.apple.com/us/app/spectrumview/id472662922?mt=8)).
## Usage:
Compile using make (```make```) and run:
```./spectrum-printer "message"```
Some additional options can be used, for instance:
```./spectrum-printer "message" lines=40 min=1000 max=2000 time=400```
Prints "message" using 40 lines (frequencies) ranging from 1000 to 2000 Hz, where each column takes 400ms.
You can also print images. To prepare image use ```./prepare_image.sh input_file output_file height``` and use image=true option.
Example:
```./spectrum-printer cameraman.pgm image=true min=1000 max=6000 time=100```
When printing images lines option is ignored.
