Starting up openFrameworks project for audio time warping. The ofxFileReader goes in addons of your OF folder, the libraries and source (chromogram, fftw and source code src+ timewarp) are probably best kept in the repository, then dragged into the project afresh. That way, as we update the repository, the code that the openFrameworks project looks for will be updated.
