Joco vs. Glee

With all the controversy surrounding Glee’s ripoff of Jonathan Coulton’s Baby Got back I thought I would makes a remix that combines the two versions. The remix alternates between the two songs, beat by beat.


At first I thought I had a bug and only one of the two songs was making it into the output, but nope, they are both there.  To prove it I made another version that alternates the same beat between the two songs – sort of a call and answer. You can hear the subtle differences, and yes, they are very subtle.


The audio speaks for itself.

Here’s the code.

Bangarang Boomerang

My latest music hack is Bangarang Boomerang. It is a web app (runs in Chrome or the latest Safari), that lets you ‘drive’ the Skrillex song.  You can freeze-frame the song on  a beat, you can make the song go backwards beat by beat, you can advance through the song at  double time, or triple time, and set bookmarks to let you easily jump to different sections of the song. It is a rather fun app that lets you feel like a musician, even if you have very little musical talent.

Watch the quick Youtube demo, and then try it yourself:  Bangarang Boomerang

The Wub Machine

Peter Sobot (@psobot ) has used The Echo Nest Remix to automatically add dubstep to any song.

The Crash Bandicoot Dubset remix is pretty wild.  Peter says that The Wub Machine is still work in progress. Check out how it works and add your ideas to the mix on Peter’s blog.

We swing both ways

Perhaps one of the most frequently asked questions about Tristan’s Swinger is whether it can be used to ‘Un-swing’ a song.  Can you take a song that already swings and straighten it out? Indeed, the answer is yes – we can swing both ways  – but it is harder to unswing than it is to swing.  Ammon on Happy Blog, the Happy Blog has given de-swinging a go with some success with his de-swinging of Revolution #1.   Read his post and have a listen at Taking the swing out of songs.   I can’t wait for the day when we can turn on the TV to watch and listen to  MTV-Unswung.

Frasier does Nine Inch Nails

Oh My –  Musician Josh Millard  has recreated The Downward Spiral using nothing but audio from the NBC sitcom Frasier. So wrong, and yet, so right.  Josh has the whole remixed album plus a video on his blog:

Sweet Child O’Mine – Vienna Style

I was wondering how far one could go with the time-stretching stuff and still make something musical.  Here’s an attempt to turn a rock anthem into a waltz.  It is a bit rough in a few places, especially the beginning – but  I think it settles into a pretty nice groove.

The Swinger

[tweetmeme source= ‘plamere’ only_single=false] One of my favorite hacks at last weekend’s Music Hack Day is Tristan’s Swinger.  The Swinger is a bit of python code that takes any song and makes it swing.  It does this be taking each beat and time-stretching the first half of each beat while time-shrinking the second half.  It has quite a magical effect.  Some examples:

Every Breath You Take

Money for Nothing


I Will

Update – a few more tracks -by request:

Enter Sandman

Daft Punk’s Around the world

Sweet Child O’ Mine

(one of my favs)

Don’t Stop Believin’

White Rabbit

(this one is hypnotic)

Swinger uses the new Dirac time-stretching capabilities of Echo Nest remix. Source code is available in the samples directory of remix.

Be sure  to check out some of the other Music Hack Day hacks like Six Degrees of Black Sabbath, Jason’s Songbird Visualizer or the Artikulator.



Earworm and Capsule at Music Hack Day San Francisco

[tweetmeme source= ‘plamere’ only_single=false] This weekend The Echo Nest is releasing some new remix functionality – Earworm and Capsule.  Earworm lets you create a new version of a song that is any length you want.  Would you like 2 minute version of Stairway to Heaven? Or a 3 hour version of Freebird? Or an Infinitely long version of Sex Machine?  Earworm can do that.   Here’s a 60 minute version of a little Rolling Stones ditty:

Capsule takes a list of tracks and optimizes the song transitions by reordering them and applying automatic beat matching and cross fading to give you a seamless playlist.  It is really neat stuff.    Here’s an example of a capsule between two Bob Marley songs:

It makes a nice little Bob Marley medley.

Jason writes about Capsule and Earworm and some other new features in remix  in his new (and rather awesome) blog:  Running With Data – Earworm and Capsule.  Check it out.

Bad Romance – the memento edition

At SXSW I  gave a talk about how computers can help make remixing music easier.  For the talk I created a few fun remixes.  Here’s one of my favorites.  It’s  a beat-reversed version of Lady Gaga’s Bad Romance.   The code to create it is here:

Here comes the antiphon

I’m gearing up for the SXSW panel on remix I’m giving in a couple of weeks.  I thought I should veer away from ‘science experiments’ and try to create some remixes that sound musical.  Here’s one where I’ve used remix to apply a little bit of a pre-echo to ‘Here Comes the Sun’.  It gives it a little bit of a call and answer feel:

The core (choir?) code is thus:

for bar in enumerate(
 cur_data  = self.input[bar]
 if last:
     last_data = self.input[last]
     mixed_data = audio.mix(cur_data, last_data, mix=.3)
 last = bar
