What is this?
For when your favorite song just isn’t long enough. This web app lets you upload a favorite MP3 and will then generate a never-ending and ever changing version of the song. It does what Infinite Gangnam Style did but for any song.
It never stops?
That’s right. It will play forever.
How does it work?
We use the Echo Nest analyzer to break the song into beats. We play the song beat by beat, but at every beat there’s a chance that we will jump to a different part of song that happens to sound very similar to the current beat. For beat similarity we look at pitch, timbre, loudness, duration and the position of the beat within a bar. There’s a nifty visualization that shows all the possible transitions that can occur at any beat.
