Some feature extraction code was based on https://github.com/ronw/frontend by Ron Weiss.
Large portions of LibROSA were ported from MATLAB code by Dan Ellis http://www.ee.columbia.edu/~dpwe/resources/matlab/.
Some spectral features were ported from original MATLAB implementations by Erik Schmidt and Jeff Scott at the Drexel METlab http://music.ece.drexel.edu/
Additional thanks to Emanuele Coviello and Erik Schmidt for testing, bug reports and fixes.
