Might be interesting to experiment with different mappings of pixel location to audio sample number, rather than just having a row by row linear scan from corner to corner.
I am curious. I do not know much about image encoding and the such. What other types are there besides linear either row by row or column by column? It seems to me that those two are the only logical ways to map pixels.
Neat. I assume it would be possible to do the same thing in reverse then? As in, use image editing effects on audio clips?
I also tried different audio compressions on the picture. Ogg vorbis even looked better than mp3, haha.
I used to play with this as a kid. I couldn't script it, but I could remove the headers from a bmp and add the headers for a wav in a hex editor. Then I tried all the effects in audacity. The resulting images were pretty cool (only grayacale). I also tried different audio compressions on the picture. Ogg vorbis even looked better than mp3, haha.
Hi HN, I just finished adding video support (and stubbed out audio support). Due to already using ffmpeg for image manipulations, this turned out to be rather easy. Give it a try using something like this: $ ./mangle.sh in.mp4 out.mp4 --color-format=yuv444p --bits=8 --blend=0.4 overdrive 17 hilbert -n 5001
This is fantastic. For folks wanting to play around with this on OSX: brew install ffmpeg lame brew install sox --with-lame The --with-lame is important if you want to process mp4s. Might want to consider putting some kind of progress indicator (simple polling on tmp_audio_in.u8 vs tmp_audio_out.u8). I ended up looking at the output directory with watch -n .5 ls -la /tmp/audio_shop-DIRECTORY I think the cleanup isn't…

Has any album art been done with this?
The author of the modular synth "SunVox" made a live tool called "PixiVisor" that does something similar. http://www.warmplace.ru/soft/pixivisor/ The last two videos on the page are particularly impressive, which demonstrate video mixing using two channels of an audio mixer, and video blurring from multi-path audio reflections.
that guy/gal is an uber engineer. love all the stuff they've made!
So, yeah, I agree. Alexander Zolotov is brilliant and prolific. The demo videos for Sunvox are worth a watch.
