sound development – status quo

Hello everybody

Herewith I want to write down the current state of the sound development which is the outcome of the last working period in may/june where we sat all together (Ole, Annesofie, Silas and me) in Copenhagen:

After diverse tests with accelerated sound recording my doubts about the results of either too simple or too hectic sound structures got acknowledged. Imagining the final exhibition which meant projecting myself into the 360 degree time lapsed panorama, I decided to work with unprocessed sound-field recordings on the one hand and with a generative music on the other hand which formalisms are based on the grammar of Inuit music.

With fading into the real soundscape while the video panorama slows down to realtime, the listener shall have the chance to immerse into the audio visual environment as deep as possible. He is now able to get absorbed by the landscape and can meet the performers actions, a passing polar bear or whatever caused the system to slow down.

When the panorama accelerates again the listener leaves the perception of time he is used to and enters artistic space. A music develops or goes ahead, it is almost not music yet and should almost not comment the visual scenery but it is connected to the movie’s parameters which are considered as of eminently importance for our artistic vision. More challenges are that the music has to be about 12 hours long and should be neither disturbing nor boring, exhausting or anything else what lets us escape from the exhibition.

Is it possible to compose a ‘music’ based on these conditions – was the question I asked myself and started to implement some ideas.

Here you can listen to one of these which uses a simple algorithm (not based on Inuit music) which controls a software synthesizer (sculpture) that uses physical modeling for the sound synthesis. This Synth was a quick decision to prevent the danger of a folkloristic/stereotypistic music and in forethought that also elements of the sound could be controlled by the movie. Just for fun I added a drumset. As one of the first tests I found this result persuasive in cases of

  • being not too much in the foreground and
  • being very much developable …. ;)

The next steps will be to:

  • find out: what exactly is ‘Inuit music’?

Starting a period of research I found the abstract ‘Cluster Analysis for Computer-Assisted Statistical Analysis of Melodies’ by Luigi Logrippo and Bernard Stepien from 1986. Herein was described a statistical analysis method based on the example of ‘Inuit Music’. Fantastic!!!. But I missed more detailed informations about the analysis’ formalism and specially the data sets of the analyzed Inuit music songs so I contacted both and was deeply moved by their response mainly the amount of time they spent to find the about 30 years old papers, making them available and writing back looong emails. It seems that I am owning now at least a statistical description of Inuit music… I shouldn’t forget to mention Ramon Pelinski. He was part of this research project and mainly responsible for the musicological work.

  • defining the right grammar and formulate a resynthesis algorithm

This is the current challenge I am working at…

  • define the sound material: instruments, resynthesis, recordings of vocals in greenland (refering to choir music), etc.
  • find the right video parameters which are able to produce an interesting, convincing and still surprising musical dramaturgy.

all best and see you soon – daniel

Camera news from the software artist’s desk

The Prosilica GX camera just works, it’s very simple to set up, and I’ve made the first openFrameworks based software sketch using the AVT GigE Vision library.

It’s a sketch, and the code is only relevant to other programmers using this camera, but I’ve put it up on my GitHub nonetheless.

Source code

Find the openFrameworks based source code in this github repository.

About the code

prosilicaAlternatingExposureSketch is a first attempt at doing continuously alternating exposures 3 steps apart for on-the fly 1080p HDR video capture.

Included is a ofxVideoGrabberProsilica addon, that implements some of the most relevant parameters for controlling a AVT Prosilica GX1920 camera and using software triggering. It is ok for trivial use, but does not provide the accurate timing necessary for high framerate usage yet. The code is based on Stephan Schulz’ code from the openFrameworks forum.

We’ve got our first camera! … and rescheduled

After a long wait in the customs (>3 months) Ole has finally gotten our donated AVT Prosilica HD camera released. Customs and overseas technology donations for art projects is a science in itself, and we had to negotiate a lot of red tape. But now we’ve learned how to do it, and that’s a subject for a whole other blog post, some other time.

For now we are really thrilled and happy to receive this generous donation and will spend the next couple of months working with the camera, sketching software to work with it. When it all works out we will receive the remaining 3 cameras.

Rescheduling

Because of the wait we have had to postpone the setting up of the research station in Greenland. We cannot be ready for our planned window in May this year. As we are all involved in several projects, next window will be in August 2012.

This means that we will have plenty of time to work on detailing plans, programming and doing artistic experiments. First working period will be this May and June, as we had all ready planned to use this time in Greenland, it is an ideal time to work together in Copenhagen and/or Berlin.

Experiments with dynamic timelapse recording

It’s been a good week in Berlin, exhibiting and working from Annesofie and Daniels’ appartment. We’ve been sketching out some ideas for the dynamic timelapse software for the research station. And doing some production related stuff. But this post is a short glimpse into an experiment with some of our footage from Savissivik, 2009.

At that time Ole worked with Quillaq on the plain at the foot of the Savissivik hillside. There they filmed a series of long duration shots of Quillaq approaching a fixed camera. These shots have been our boilerplate footage for experimenting with ways of doing the dynamic timelapse footage.

The challenge is to find an algorithm that will speed up the video when there is low activity in view, and slow down when there is high activity. High activity can be ‘movement’, but also ‘closeness’.

Here’s a small screencast from the software sketch – with a guest appearance by Silas, our newest project member :)

Inland exhibition in Copenhagen

Ole Kristensen created the video installation ‘Inland‘ for the second run of the Frost performance in Copenhagen. It is based on footage from our research trip in Nothwestern Greenland 2009.

Frost is a modern dance performance by choreographer Tina Tarpgaard, involving Ole as software artist for the interactive scenography. It was commissioned by Danish Dance Theatre to premiere in the fall of 2009, where it received a great response. After winning the prestigious Reumert award as the Dance Performance of the Year, it enjoyed a completely sold out second run in Dansehallerne on the old Carlsberg Brewery. Some of the scenes in FROST are directly inspired from our travels in Greenland. You can see more about the FROST performance, including video documentation, on Ole’s website.

Arriving in Savissivik

After a 6 weeks travel along the remote north-western Greenlandic coastline, a long endless day with coincidental pauses of sleep, 15 days in a kayak, with the pleasant break of some local kaffe-miks, some hot showers, a 12 hours journey in a small speed boat between floating mountains of white in all shades leading to the first encounter with our present destination, Savissivik, a small hunters settlement with 85 inhabitants and a beauty which surprising magnitude teased my vision and made me choose this special location for the site of our one year research station.

Med kayak fra Upernavik til Kullorsuaq på 3 uger

Jeg ankom til Upernavik i juli måned. Efter få dage lagde jeg ud på en længere kayakekspedition, ifølge med min bror, en kurator fra Israel og vores lokale guide.

Langs den nordvestgrønlandske kyst er man mange dage undervejs uden at møde det der bare ligner et menneske.

Vores kayakker lå derfor lavt i havoverfladen, tungt lastede med mad, brændsel, stormkøkken og et enkelt par ekstra sokker. Døgnene smeltede sammen i en glitrende havoverflade af is i lysende flader. Dagene planlagdes ikke længere efter solens vandring, i stedet blev selve havets rytme og skiftende strømninger vores parameter; hvordan det rejste sig og veg tilbage som et stort sovende dyr, der i den stille nat holder vejret, for i de tidlige timer igen at ryste sin bølgende pels.
