Flutterby™! : The Swinger

Somehow we missed "Music Hack Day", but luckily we can partake in some of the awesome that it produced before this becomes the next autotune. The Swinger:

This command line python script (about one line of code per hacking hour) takes two arguments (i.e., a song and a swing factor) and alters (i.e., time-stretches) every beat, one at a time, to give it a swing feel. It works by stretching and compressing every half beat to complementary durations, pulling and pushing the audio, while retaining the original tempo.

But, really, screw the code, what you want is results. "Sweet Child of Mine" is awesome, as is "Money for Nothing" once you get past the intro. Listen here: http://musicmachinery.com/2010/05/21/the-swinger/
