Wish you could make any track swing? Tristan Jehan, grad of the MIT Hyperinstruments Group and c0-founder of The Echo Nest, made that happen at San Francisco’s Music Hack Day. The Python code uses the Echo Nest’s sound-processing magic, available to the world via open Web APIs, in order to analyze tracks and re-synthesize them in swing form. The results are — well, somewhat terrifying, though in a cool way.

Paul Lamere of Music Machinery points this our way and has a ton of examples on his terrific, sound geek-friendly blog. (The post must have captured people’s imagination, as it’s spread virally online, but I know this is the only site you read — right?)

The swing is definitely of the consistent/mechanical variety, but … well, it does serve to prove that not everything should swing, but anything can.

My picks for the trippiest examples:

Enter Sandman- the Swing Version by plamere

Around the World – the swing version by plamere

  • While it funks up the Metallica track, to me it has the opposite effect on the Daft Punk track, which originally is quite funky already. Like it counter swung in a stobe type effect.

    @Ronnie
    It does funk up Metallica! There are limitations – the track gets very glitchy and stuttery when you get to the final break and coda (around 4:28), it kind of falls apart because of the counter-time drum hit. Apart from that, it makes for an interesting alternative version of Enter Sandman!!

    I also agree with you about the Daft Punk track – in this case, Swinger kind of kills it. I guess some songs shouldn't swing at all in first place!

    What's the difference between this, and applying swing to audio clips in Ableton?

  • nick

    jeebus-the words "mechanical" and "swing" should never be used in the same sentence, EVER.

    you truly can't fake the funk.

    pass.

    Hey, that's a really cool format for posting music.
    Is there any way I could buy/borrow/use that bit of code?
    I've been looking for a cool way to post music up, and that's really great.

    I think it's the guitar solo that throws off the beat detection in Enter Sandman. After that, instead of putting the long space after the 1 and the short space after the 3, it does the reverse. I'm surprised at how hard it is to enjoy listening to the result of that switch.

    I think Around the World is a huge improvement. I always felt that it, along with One More Time, was one of the most tedious Daft Punk tracks. It's quite good with the heavy swing though, I even managed to listen to it all the way through.

    I love this kind of stuff. These are hilarious. I tried to install and use Echonest but, like most powerfully cool stuff, it's beyond me. I need a GUI version – preferably a physical panel with lots of knobs, buttons and blinky LEDs.

    Seriously though, this would be great for remixing.

  • The Edison audio editor in FL Studio has a tool called Claw Machine that does this.

    Theres also a version in its piano roll to do the same to MIDI.

    @Vors "What’s the difference between this, and applying swing to audio clips in Ableton?"

    I'd say about $450…
