JPEGlitch
I've been experimenting with glitched JPEG encoding in Flash and have created a version of Thibault Imbert's optimised JPEG encoder that gives control over various glitch parameters.
JPEGlitch Example
A simple test suite that lets you control parameters, experiment with the JPEGlitch class, and load/save images locally. This example uses the minimalcomps ui component library from bit-101.
JPEGlitchRhythm for HYPE
I also made a rhythm for the HYPE framework using the JPEGlitch encoder.
This example is an audio visualiser based on a HYPE sound analyser example and plays 2 short tunes endlessly. The rhythm encodes and re-encodes a bitmap, adding the freshly rendered oscillator canvas on top each time.
This is also my entry to the HYPE 'Friday 13th' competition.

Update 14/01/10 - JPEGlitch get's an honorable mention in the HYPE competition
And now, some JPEGlitch / JPEGlitchRhythm pics...
Great stuff Mike!
as author of designing imperfection and a glitch afficionado and a friend of madebypi, I totally approve of this work, its one of the coolest things Ive seen. when I saw AS3′s bytearray stuff I thought it wont be long before someone does this. very impressed and very happy to see it. well done.
Hi Iman, thanks for the feedback, glad you like it
I’ve been a fan of all things glitchy for a long time now, and I plan to continue improving and expanding on this little experiment when I can.
Sounds brilliant Mike. keep us posted on future developments. This is the kind of stuff I dreamed of seeing when I first started experimenting with the glitch.
Hi Mikea,
I was just reminded of JPEGlitch when I stumbled upon http://blog.soulwire.co.uk/laboratory/flash/as3-bitmapdata-glitch-generator – and a thought struck my mind: it might be cool to glitch the sound aswell.
So I took the five minutes, downloaded your source and gave it a try.
The result sounds like my good old SoundBlaster on Windows 3.1 with an incorrect buffer size set in its driver

flashgordon – That’s great! I can’t believe I didn’t slip a little bit of audio glitching in too…
I’ve been thinking of making a little suite of glitch-tools, perhaps as an Air application, and audio glitching will definitely be a key feature.
Cool – that might become a great tool for vjaying. Keep on glitching!
Would love to use this as a visualizer for my tracks. Would be cool to be able to load an mp3 into it and embed it.
