The Agents Play Their Music

DisplayAOSCWeb

Bringing the A.O.S.C. project to the next level – the agents play their music!

In the previous setup the agents functioned only as the ears of the system, listening to the acoustic environment and sending the data of the audio spectrum to the main server. Everything else, the analysis of the data streams, the resulting calculation of the parameters for the sound synthesis as well as playing back the music, all that happened on the server side.

Now we bring the music back to the agents!

The server only does the calculations and sends the stream of parameters back to the agents where the music is generated by a Pd patch.
That means, you can sit beside the agent, listen to your actual acoustic environment and – by using headphones – to the collective electronic soundscape composed by all the networked agents.
Now this system offers the possibility to directly observe the impact of the acoustic events at the agent’s place as well as direct acustic interaction with the system.

In the moment we have four agents running: Toronto, Lviv, Sydney and Bonaforth.

Currently we are working on the algorithm which is receiveing the data stream and calculates the control data for the music.

Here are some snippets.

SeaSwallow Project – Network

overview of the network built for the SeaSwallow Project
blackhole-factory

 

For the SeaSwallow project we set up a network of Max/MSP patches connected locally at the performance space in Braunschweig and over the internet with the 2 remote places.

The tasks of these patches are to get sensor data from the 3 places and to visualize them, to manage a database as a shared memory of the performers, to display this as an OpenGl graphical user interface (SwallowWorld) and to playback the audio and video files from the database while using this 3D interface.

In addition to this Max/MSP network we used the eJamming platform for realtime audio networking.
The original plan was to do this also in Max but bandwidth limitations (upload speed of 450 kbit/s at one place) forced us to switch over to eJamming.

Each of the three places is equipped with the SeaSwallow SensorKit, a Max patch called SwallowWorldNy / Syd / Bs and eJamming.
All the other Max patches are running on computers in Braunschweig.

The SeaSwallowSensorKit
It consists of an Arduino UNO board running a sketch for reading analog sensor data and sending it to a serial object in the SwallowWorld… Max patch.
Attached to the Arduino are 3 different sensors:
1. a LDR (light dependent resistor) to mesure the amount of light in the environment
2. a temperature sensor (DS1820 Dallas 1-Wire Digital Thermometer which requires the OneWire.h and DallasTemperature.h libraries on the Arduino)
3. a 3-axis accelerometer (MMA7361LC) which is fixed to a wrist band. Each performer is wearing one of this motion sensors, sending out a permanent stream of his handposition to the other places.
In combination with a button in the Max patch to switch navigation mode on or off the performer can navigate in the OpenGl world (SwallowWorld), moving the arm for looking around, fast shake to move forward or stop, double shake to move backwards.

SwallowWorldNy / Syd / Bs – Max patch
This patch is managing the peer-to-peer network connections to the other places. It displays the SwallowWorld and the 3 hand models as OpenGl graphics and containes the button to switch one’s own navigation on or off.
The sensor data coming from the Arduino is send to the other places using the udpsend Max external.
The camera image from New York and Sydney is send to Braunschweig as a mpeg-4 compressed video using the vipr external  from Benjamin Day Smith in combination with jit.net.send.
The patch receives the motion data of all 3 performers and displays it by controlling the OpenGl hand models: moving it and changing it’s color for navigationOnOff, move forwards, backwards or stop.
It also receives the data for view point and lookat in the SwallowWorld calculated in the NavigationControl patch in Braunschweig to syncronize the movements of all three SwallowWorld graphics.
At last it receives the processed video stream from the DataBase in Braunschweig.

The Max patches running only in Braunschweig, connected over the internet to the remote places:

NavigationControl – Max patch to receive and manage the incoming motion data and use them to control the OpenGl world and the playback from the files in the data base.
It receives the data from the 3 motion sensors and the information about who is in navigation mode.
As soon as one performer is in navigation mode the patch uses his motion data to control the view point and lookat parameter in the SwallowWorld.
For this we modified the z.glNav abstraction from Zachary Seldess.
If more than 1 performer switches on navigation mode the patch calculates the average of the data. This can be used for group flights (what we call swarm naviagtion).
The SwallowWorld functions as a 3D sound/ video map.
An algorithm (Pythagoras in 3D) is permanently calculating the distance from the view point to the position of the files in the SwallowWorld to decide which files to play. Files will be chosen when the viewer comes close. In case of audio the distance defines volume and the mix of the closest points. In case of video files the distance defines the grade of distortion using alpha masking.

DataBase – Max patch containing the coordinates of all places and files integrated in the SwallowWorld
The files are sorted by different types like basic point (geographical place positioned on the edge of the globe by using it’s GPS coordinates), video, interview, music, filed recording. Each type has a different color in the 3D world.

Ethernet Orchestra UpStage Festival

From the Ethernet-Orchestra website:

121212 UpStage Festival of Cyberformance will take place 5-12 December 2012

Live A/V performance Oceans Between Sound featuring Graziano Milano

Schedule and direct A/V links

Exploring interdisciplinary and intercultural networked creativity, this audiovisual performance will feature Ethernet Orchestra collaborating with visual artist Graziano Milano mixing visual collages in VisitorsStudio.

The inspiration for the performance Oceans between Sound considers the ebb and flow of network data as metaphor for the world oceans separating the members of the ensemble and their dispersed lives.

Ethernet Orchestra are streaming their networked improvisation via liminal sound net radio and live visual mixing by Graziano will be in VisitorsStudio. To experience the A/V shows online go to UpStage or open the urls above in separate browser windows.

Online as a live sound Internet broadcast and Graziano. Online audiences will open VisitorsStudio and the radio portal in separate browser windows to experience the full audiovisual performance.

There will be two shows for audiences in both hemispheres – view schedule times for more details.

The event is also showcasing earlier works by artists working in the field called “Walking backwards into the future” – a programme of 19 remounted cyberformances from the past five festivals (5-11 December). Follow this link to the schedule and time converters. more details

We are very proud to announce the release of
Ethernet Orchestra – a radio feature by Mirko Heinemann

This is a 2 hours radio piece. It presents live recordings of five concerts done by Ethernet Orchestra during the past 18 months. The band members give background informations and personal reports about the idea and the experience playing in networked improvisations.

With this collection it is possible for the first time to get an overview over the creative exchange and to listen to the wide range of beautiful and exciting music of this extraordinary musical project.

blackhole-factory is happy about the possibility to produce this piece in collaboration with Mirko Heinemann, a great journalist, who did reports on our work already in other situations.

Thanks to DEGEM radio for hosting the show in their series Sounds only, streaming it 2 times a day in Dezember 2011 and Januar 2012

Ethernet Orchestra – a radio feature by Mirko Heinemann

Ethernet Orchestra is an Internet based networked music ensemble founded by musician and writer Roger Mills, exploring cross-cultural improvisatory collaboration through telematic audio platforms. The ensembles live performances occur in both physical and virtual spaces, and often include collaborations with networked live cinema artists mixing visual montages to the networked stream.  The core members of the ensemble  play an array of cross-cultural instruments including Turkish oud & bendir,  Mongolian horse fiddle and throat singing, guitar, trumpet, sax, voice and electronic processing. Recent live performances include Kunstmuehle Gallery, Braunschweig, Germany, O-Town Sound, New York and Bon Marche Studio, University of Technology, Sydney.
