Judging from the WP Stats, my posts about the PaulStretch extreme audio timestretching application are by far the most popular blog posts I’ve ever made, indeed I think people will be downloading it after I’m dead if this domain outlives me.
Well, today I took the time to ‘refresh’ the PaulStretch stuff. This means I updated all the libraries it depends on to current versions and rebuilt the program. I don’t mess with the program source code itself — nothing has changed in appearance or tools.
The one thing that has changed — and it’s a biggie! — is that it now can load MP3 files for processing without crashing. Huzzah!
If you want to know what I’m talking about, check the original post here. I’ve updated the build scripts but the instructions here still apply.
The application: http://www.cornwarning.com/xfer/PaulStretch-OSX-x386.dmg
The build scripts: http://www.cornwarning.com/xfer/PaulStretch-OSX-Build.tar.gz EDIT: I had the link wrong. Sorry — one letter off.
The Disclaimer
I did this for my own amusement. I don’t want to be the guy providing tech support on Paul Stretch. So try and take care of yourselves. As far as I know no one has bothered to try and use my scripts to compile it for themselves, which I find annoying because A) people are so damn lazy and B) there should be hundreds of people around the world capable of building this program and troubleshooting any issues that come up. That’s why there’s no PPC or Snow Leopard build avaiable — not one damn person stepped up.
And as to the functioning of the program itself, or any new versions, that zynaddsubfx dude who wrote it went AWOL shortly after releasing the program. He’s never responded to any of my e-mails.

I assume that, by now, you’ve heard that someone ran a Justin Bieber track through Paulstretch set to 800% and came out with something that sounds pretty much exactly like Sigur Ros: http://soundcloud.com/shamantis/j-biebz-u-smile-800-slower
Yeah, I saw the posts about the Justin BIeber stretch thing. And lo and behold overnight I went from 70 hits/day to 2500 hits/day.
Just tried to build this on a MBP3,1 running OSX 10.6.4 and got these make errors:
make[2]: *** [CMakeFiles/paulstretch.dir/PAaudiooutput.cpp.o] Error 1
make[1]: *** [CMakeFiles/paulstretch.dir/all] Error 2
make: *** [all] Error 2
Along with several scope errors and undeclared header errors. Just passing the info along. The app you compiled works fine I think, though it may have a problem with adjusting the window size.
No idea what the problem is — the error message you included is completely uninformative. Normally there would be more specific information if a compiler error aborted the make. The script I wrote attempts to be comprehensive in downloading and building prerequisites, but really if anything goes wrong, you have to put on your programmer hat and figure shit out, since I can’t shoulder surf and troubleshoot it with you.
Really cool little thing this is. Unfortunately my machine doesn’t support it. I’m using a Mac (not intel). Any help? Thamks in advance.
The Powermac app is here: http://music.cornwarning.com/2010/04/08/paulstretch-2-0-os-x-ppc-build/
Would it be a reasonable task to port this application in some form to the iPhone or iPad? I’d love to listen to stretched versions of my iTunes music at work, and would put in the time required to do an iPhone port if I get the time.
I think it would be possible, but it won’t be me doing it. You’d have to change it you use Cocoa native for the interface, and I don’t have any experience doing it. The guts of the algorithm wouldn’t have to change but all the UI stuff and audio connections and event handling would be different.
great software! i tried it on otto von schirach. it’s fun!
thank you.
I dont know why you would need to compile the APP when the DMG file supplies you with a built version. I an using an intel iMac and the DMG works fine guys. Just make sure you download the ‘DMG’ file and you should be fine.
LOVE. Thank you SO much for making/posting this. Brilliant way for me to create my perfect “dreamscape” writing background music. You Are My Hero.
Hmm… this thing just adds a horrible crackling noise to the file, while also messing up the audio driver, so the crackling is present when I for example play anything in iTunes.
Ah nevermind, it works fine when I just use the iMac’s built in headphone output.

its not working for me
See other reply. You might have some luck if you build it yourself, but if you don’t regularly build apps from source, I doubt you’ll have much luck. Upgrade to Leopard or Snow Leopard.
