// Adding the buffers in array ~files
// files should be in ./files/

// This variable sets where the script starts reading from the file. Default is 25.

// From the README file:
// The script will read the files from their start point. If you are providing files that
// are entire songs (from an music album, for example), it is likely that they will have 
// a few seconds of silence in the beginning, which would make some parts of the 
// resulting song not so interesting (particularly the first seconds, that are made out 
// 	of several tiny bits of tape). To fix this, you can change where the script will
//  begin reading the files.
