This is an implementation of a group humanizer for the Sonic Pi program. The programming language is Ruby and the original paper is here: http://www.nld.ds.mpg.de/~holgerh/articles/Hennig\_2014\_PNAS.pdf

Degrade effect for Sonic Pi

Our old friend Tidal has a function I quite like - degrade

Tidal is a pattern based language and degrade simply drops an event from a pattern 50% of the time.

input: [1,1,1,1,1,1,1,1]

-> degrade(input)

In OCR, everything seems to be using tesseract which is a huge, complex library with lots of dependencies.

Here's an alternative toolchain that shows potential and is much quicker to use

brew install pdfimages
brew install gocr
brew install ocrad
