Sound A Day – 03

stretch

I often like to use the freeware open source application Paul Stretch to create drones, and pads. Its uses don’t stop there, I’ve utilized its incredible stretch algorithms to lengthen.. shorten.. process dialogue…sfx…create looping soundscapes. Here are some examples of Paul Stretch’s incredible stretch technology. The original source is from some random patch creations I was working on(Again recording audio the whole time). Listen to each stretch example and notice how the original integrity of the sound is maintained. Pretty Impressive!

    The OSX port of Paulstretch has a permanent place on my dock. Just when you think the program is a one-trick-pony it surprises you with some amazingly diverse results.

      I think its a sleeper. Not many people know about it.. and are sometimes turned away by its less than swanky facade. I find it to be invaluable. Glad you dig it!

    I am curious.. as I’m new to audio manipulation. Why not just use ableton’s warp to stretch audio? Does it degrade the sound? Thanks for your time, and keep it up!

      Hey Ben. Ableton’s warping is actually really good.. however when you try any sort of ‘extreme’ stretching you get quite a bit of artifacting no matter the grain size/envelopes/algorithm. I find that with paul stretch its an extremely fast/efficient and quality way to achieve some really really crazy stretches. The entire audio file I stretched for this example was approximately 22 minutes in original length. Stretched to 63 times its original it was well over 23 hours of audio. I dont think it would be practical to attempt this in Ableton. I think the lack of a visual event system in Paul Stretch works to its advantage over Ableton for these specific uses. Its a really cool program.. you should check it out. Just another tool in the sound design/music production arsenal.

    The preview function is messed up on my machine.  The audio comes out choppy and skewed.  This also happened once when saving a file… although it seems to be fine now.  Great program; much needed update, as the earlier version's port has stopped working with recent versions of OS X.

      Ya… it occasionally has some playback issues for me as well. It all depends on the window size you set for playback. I tend to keep it at its default settings and it works nearly most of the time.
