I saw the recent thread about beat detection and recalled having seen
this link but didn't check it out.
Don't know how it is done, perhaps I'm wrong about it using beat
detection, the result is really quite amazing though :-)
Apparently all done in python:

Agreed, this is a lovely example. It uses the Echonest API, which is
a web service API so unfortunately all the really interesting stuff is
hidden behind the web service.
Here is a quick shell script that does the same thing using only free
(i.e. GPL or BSD) software:

You'll need vamp-simple-host, the Vamp aubio plugins (or the QM plugin
set, but that doesn't meet the licensing requirement) and Rubber Band
v1.5.0.

Well, the particular application is quite a simple one -- this is a
ten-minute script when you have the tools, which of course we do. I
was kicking myself when I read some of the publicity the Echonest hack
generated; it's such an appealingly foolish idea.
Amusements aside though, I'm kind of ambivalent about this sort of
technology -- sure, it's a drug which gives you a great ecstatic high,
but hey, I've just spent ten minutes on something which turns an
unlimited amount of serious expressive work by other people into an
object of the briefest light entertainment. I hope the future of
music technology is something more than just this.

I agree, and was thinking something similar... but I was
also in a little amazement at how many people were
responding to this little 'toy.'
Like it or not, musicians are dominated by this sort of
externalism -- especially with respect to technology. In
that respect, I'm finding that how it looks and feels means
as much (or more to them) than how it /sounds/.
So, a little bit of this sort of PR for linux audio would be
a Good Thing, IMHO.

This is a tool for drawing moustaches on music. Take straight 8th's and turn them into

it's kind of a juvenile joke, it's ephemeral, once you go "ha, tha'ts

Apt comparison. Not necessarily a bad thing, drawing moustaches is
something my kids like very much :-) (and me too!). I don't want to
grow up more than I have to.
Also the technonerd in me really likes this type of application I
hadn't realised possible.
For now it's a moustache-technology, but there must be creative things
that it can be used for too.

By the way, your script mentions that QmVampPlugins are not open source:
http://all-day-breakfast.com/m/swing.sh
# any plugin that produces beat times will work here;
# qm-vamp-plugins:qm-barbeattracker:beats is usually more stable than
# this, but it's not open source so I didn't use it here
Where http://isophonics.net/QMVampPlugins says "These plugins are
provided in binary form only and may be used for any purpose, or
redistributed for non-commercial purposes only." -- so I guess I'm
good if the QmVampPlugin is provided as a "web service API" (e.g.
http://nielsmayer.com/ts-episode-timeline.png ) since I'm not
redistributing any binaries -- just data produced by vamp --> JSON,
like http://www.isophonics.net/sawa/ but also very different as I'm
focusing on immediately usable and ready-to-hand AJAX-style Javascript
UIs for the data.
What is confusing is how come there are Linux distros that are
distributing the QmVampPlugins in binary form? Are they "out of
compliance" or do they have a special deal with http://qmul.ac.uk ?
Any chance you can convince your colleagues to outright open-source
them so they can be included in distros like Fedora? ("Version 1.6.1 –
Copyright 2005-2009 Christian Landone, Martin Gasser, Chris Cannam,
Christopher Harte, Matthew Davies, Katy Noland, Thomas Wilmering, Wen
Xue, Ruohua Zhou, and QMUL.")
And yes, it's perfect that the VampPlugins provide such good timing
info. One of the fun things to do with my Vamp-Plugin consuming web
interface is to use segment or beat points to reorder, loop, or remix
internet sounds, which happens to be a nice side-effect of the project
I'm trying to launch, though not the intent of the project.... I call
it the "internet sampler feature"
Niels
http://nielsmayer.com
PS: I think it would be great if all major linux DAWs (esp.
rosegarden, qtractor, ardour) had a generic "audio event timing bus"
that would allow VampPlugins to analyze audio, and generate visual
tags/markers/hints on any audio segments used within the DAW.

Well, the implication is that that's OK if you're not making money from it.

No, there aren't any deals like that. I don't know whether individual
distributions are in line with the terms or not, I suppose it depends
on whether they're non-commercial or not. However, the terms did
change a few releases ago -- that non-commercial clause first appeared
at some point after 1.0 -- so it's possible some distributors might
not have spotted the change.
Any chance you can convince your colleagues to
outright open-source

This question -- which is quite a common one for academic institutions
to face -- is not only down to the individual contributors but also
the institution, and it's partly a question of intent ("what else can
we do with this software?") and partly a practical one ("is there
anything in here we can't legally publish that way?")
Queen Mary university, like most publicly funded bodies, is pretty
open about its work with things like Sonic Visualiser under the GPL,
the Vamp SDK under a BSD licence, some open source plugins including
the rather interesting VamPy, and various other bits and bobs (see
http://isophonics.org for some more stuff we publish). But there are
always tricky areas, and at the moment this is one of them.
It's a problem that we're going to be trying to make more explicit: we
are setting up an institute to try to help academic software
development become more open (you can read the initial blurb at
http://soundsoftware.org.uk/, it has neutral UK government funding,
I'm going to be working on it, and we will be hiring) and as part of
this initiative we need to try to work out answers for the sorts of
questions institutions (including QM) quite legitimately face with
this software. Keep an eye on it, it may become rather interesting.

I read it to say that you can *use* it for any purpose, commercial or not but

If that is not the intent, perhaps some attention should be give to the
language to make the actual intent clearer.
