Sweet Delight and Endless Night 111110

I haven't been playing with MaxMSP a lot lately, but Palle Lindqvist gave me a good excuse, enter S.T.M.D



Initially I played a bit with the audio input from an electronic stethoscope, trying to trigger actions on heart beats. I had no clue what Palle, had in mind until recently.
So what is S.T.M.D. ? He describes it as: "Experiential live audio-visual room installation. ". Conceptually I see it as a link between your inner and outer self, both literally and metaphorically, but it all makes sense instantly when you experience it...

Speaking of which, you are invited to the Sweet Delight and Endless Night group exhibition.

Plainly put exhibition = prohibition of inhibition, so do expect a surreal experience.
We'll be at 82 Great Eastern Street, from 7PM to 10PM.

Oh, I haven't talked about the technology yet...Would a magician give away his tricks ? Maybe after the show, so check back later for the nerdy bits.
All I can say for now is: lights, cameras, electronic stethoscope.

UPDATE:

Well, not to bad for something pulled of quickly, but certainly not ideal. The complete system was quite complex: Heart beats detected through an electronic stethoscope and a webcam are the inputs. The outputs are lights controlled using
the DMX protocol and the heart beats and a projector displays the webcam feed on a plane drawn with OpenGL that gets 'exploded', again, on heart beats.
There was little time and many things to do, so in short: lots of dirty little hacks.

Here is a stethoscope signal processing test patcher:

One of the trickiest part was getting accurate readings, which were almost impossible in the installation's environment: a small room next to a massive room which resonated with the audience of multiple other pieces, but that's what a group exhibition is about. On the other hand, given it was an independent effort by a few students, it turned out ok.

Here is a fragment of the recordings Palle did. You will notice toward the end of the video that the beats (distorted webcam feed) isn't all that accurate:

The Mother Mind is free



The Mother Mind was released to the curious hearts and minds visiting Goldsmiths.
As mentioned in the previous post, balance shifted from a lot of live video processing,
to less. Instead the voice of Helene took over the performance, and technology just
aided here and there, trying to disguise itself as magic.

Here is a fragment from the performance:



For documentation purposes, here are is a video of a previous Max patcher:

Colour Sound from George Profenza on Vimeo.



Using jitter, I analyze the average colour in the video. The amount of red is mapped to the volume of the wind track and the amount of blue is mapped to the volume of the chimes track (both sounds from freesound.org).

The tracks were randomly chosen, but the Wind track seems to go with the waves somehow.

Here are some screenshot :

Mother Mind







About a month ago I had the pleasure to meet Helene Nymann on the steps of Goldsmiths University Library. Long story short, I did a bit of research into sound, film, film sound and soundtracks, but didn't have the chance to work with great material, and Helene had great video material and no sound.

We tried a few simple techniques using Max/MSP/Jitter to analyze the video and alter pre-recorded sound. Helene also wanted to bring something new into this and tries to blend film, performance and gallery space into one. If you're interested in experimental video, live performance, and a bit of live signal processing, you're more than welcome to view Helene's project: Mothermind.

The performance will take place on the 17th of June, from 6PM to 9PM in Goldsmiths Richard Hoggart building(entrance 26 on the map bellow), in room 328.
