Termfall FFT Waterfall Plotter v0.1

Elizabeth Evelene Ariane Amelia Ultraviolet, June 2019

AGPL v3

What's this?

It's an FFT waterfall plot for your terminal! Now you can generate sonograms and stuff without needing a GUI at all!

What it does

It takes the FFT of the data from stdin (it expects u8 samples for now) and emits a waterfall plot using block characters and ANSI color escapes. You will need a 256-color-capable terminal.

What's it useful for?

Audio? Maybe? Who knows. It just sounded like a cool idea, honestly.
