a weird performance i did last weekend based off my piece, magnetic field recordings:

I have a longer piece that I cut to a nice stopping point I just need to upload!

Here’s a video for a new noise project I’m doing. I was trying to get something slowly audio reactive over the course of the track. The ffmpeg parameters are below if you enjoy this effect!
ffmpeg -f lavfi -i “amovie=2021-04-16_increasing_anger_n.wav,asplit[a][out1];[a]showspectrum=s=720x540,scroll=v=-0.0002:h=0.0001,lagfun=decay=0.999,tmix=frames=2:weights=‘-0.96 1’,eq=contrast=1.5,vignette,scale=1440x1080:flags=neighbor,format=yuv420p[out0]” -crf 22 -ab 256k increasing_anger.mp4

Here’s a playlist of 5 videos I recently recorded of a relatively simply Video Synth patch consisting of a few LZX modules & some DIY builds: Fox’s Shutter, VSig’s GrainBrain and the Castle Quad-Gate from Philip in Toronto.

This was my very late submission for the birthday bash. I dont know if It got played because I unfortunately couldnt watch it all but here it is for anyone interested.
I plan on doing a continuation of this to the entire Ghost in the Shell OST. Im also toying with the idea of doing a circuit bent mashup with the live action film.
For anyone interested this is a DVD of the 1995 Ghost in the Shell. The signal chain is DVD player → Circuit Bent Radioshack/Archer Video Enhancer → Prime Image Penta II TBC → DataVideo 500 mixer → Dell LCD → Canon Rebel Ti

First time poster, Long-time lurker and learner here. After about 2 years of reading, learning, building a system, and getting inspired by all of you, I’ve finally started to do some short videos for a cassette that I’m releasing next week. It feels so great to be sharing something finally!

I know this is almost a year old, but I just dug through these older posts and this is awesome! Is it all AVE5 feedback (looks like that to me)? Would be interested in hearing how you made this.

thank you! no ave5 in this. it is mostly 2 mx50s chained together in a feedback loop, but i have modded the mixers to receive control voltage from my modular synth, so that is why is looks like there are two mixer wipes dancing around each other. unfortunately one of those mixers died a few months ago, f. The last part is an oscilloscope being keyed into an optical feedback loop where the camera is going through a tachyons+ processor.

Wow, really interesting how similiar the feedback and the mosaic effects look to the ave 5. Thanks for the explanation!
And really cool with the osciloscope and the t+ gear. We did that, too! Do you also use osci studio?
i have never used oscistudio but it looks cool. the idea of drawing something first and then hearing what it sounds like instead of making sounds and seeing what it looks like sounds fun
Yeah, If you Sample the sounds on an audio Sampler you can perform them live and use audio effects like delay and eq to manipulate the image on the osciloscope. Great fun!
Now I’m trying to convert colors to sound. The image data of the animation runs through several filters to create the graphic effects. In the last filter the image data is analyzed at two positions. Per position it is a small square area that is sampled. A single point would be too affected by image noise and rounding errors. For each area, the averaged color, saturation and brightness are calculated. These values are then sent via Open Sound Control. 25 OSC packages per second.
SuperCollider receives this data stream and uses it separately for the left and right audio channel. The sound synthesis is thus continuously re-parameterized. There are no discrete events that are sent to SuperCollider. Thus not suitable for an envelope with attack, sustain and release time.

Hey guys!
This is my recent video.
Made a tool in TD, mapped all controls i needed for nanoKontrol2, also made stuff audio reactive and jammed for couple of sessions.
Hope you gonna enjoy!

Searching for a numbers station
The footage from the ISS is from the year 2015. 4 commercial HDTV cameras were in operation there. There was then a few years of video stream from the ISS that everyone could view or record.
The sound comes from numbers stations of various intelligence agencies. These recordings were collected by www.numbers-stations.com.
The graphic animation is permanently sampled in 4 moving areas. With the color values of these areas the announcements of the numbers stations are continuously overlaid.

The scripts for the quad channel mixer can be found here.
http://digital-defect.org/en/post/color2sound-mixer/
The Clojure script controls the animation. The image data is optically overlaid in the third filter. This is the filter where the color values are sampled and send via OSC.
The SuperCollider program loads 6 prerecorded audio files to remix them continuously. Controlled by the color values.
An example with stereo panning. Another attempt at converting color 2 sound. Best to listen with earphones.
Made with SuperCollider and openFrameworks.
