New Paulstretch OS X build

As software projects go, PaulStretch is rather a shadowy enigma. Since I did the initial Mac OS X port, I’ve had very, very sporadic communications with the author Nasca Octavian Paul about it.

Then there’s the issue of versioning. Paul started a github repository, but it hasn’t been updated since March. It’s currently at version 2.2.2, but the only difference between 2.2-2 and 2.2-1 is that the version number it reports has changed.

At any rate, today I did a new build which is 1) OS X 10.6 (forward compatible with Lion, but perhaps not backwards compatible to Leopard or Tiger) 2) Up to date build, incorporating all of Paul’s changes. I also spent some time playing with it to make sure it works properly.

You can download it here: http://www.cornwarning.com/xfer/PaulStretch-2.2.2-OSX-10.6.dmg

It also has the latest refinements of the build scripts used to build PaulStretch from source. I use CMake, which is Kitware’s cross-platform build tool. CMake keeps getting smarter, and my CMake recipe for PaulStretch will download all the prerequisite libraries, build them, and then download the PaulStretch source, build it, and generate an Apple App Bundle.

And CMake really is cross-platform — the same build recipe will work unmodified on Linux (which I have tested) and possibly on Windows (which I haven’t tried).

If you still have a PowerPC Mac, you can try using http://www.cornwarning.com/xfer/PaulStretch-OSX-PPC.dmg which a friend of mine built, but it isn’t the most recent version of PaulStretch.

    Thank you for porting this. I plan on destroying “Get Lucky” for my radio show.

      Paulstretch is cool, but honestly, it kinda makes everything sound the same. I can tell when people use it in tracks after 5 seconds. So Get Lucky probably sounded like Justin Bieber sounded like Bjork after being stretched.

  2. Try stretching something other than pop music because most of it sounds the same to start with! I stretched some 1960′s electronic music and it was way cool!

    Very good true observation, Tony Zilincik. I’ve gotten really interesting results using all kinds of stuff, and feel that the least satisfying results (when trying to create sounds for my own use) come from stuff that is beat-heavy &/or heavily compressed. The (generally) more sparse, dynamic source files seem to result in stretched output files with loads more timbral contours & magical tones. A lot of those random, miraculous little tones that might pop up for a second can so often inspire a whole piece or song.

  4. How hard would it be to port Paul’s amazing soft synth zynaddsubfx to os x? I may have asked this already. I would be willing to help. I’m running os x mavericks w/ newest version of Xcode.

    • chaircrusher says:

      I haven’t looked at how hard zynaddsubfx would be. If he used the same cross-platform libraries, probably not too bad.

      I really wish the FLTK people would do a proper 64-bit port; PaulStretch is stuck in 32-bit land because FLTK uses a legacy Apple toolkit.

    Thanks for this! Was bugging me that it didn’t have an icon so i made one quickly, if anyone else wants it you can grab it here: https://www.dropbox.com/s/cmdalfdubx7udqq/paulstretch.icns to change the icon just right click on paulstretch.app > get info, then drag the paulstretch.icns file on top of the little missing icon symbol next to where it says paulstretch.app

  8. I try using Paulstretch but it always adds this crazy static to my tracks…any ideas?

    • chaircrusher says:

      Other people have fixed the static by changing audio devices. I’ve never encountered it.
