Session 3: On Mapping - Techniques

Tuesday, December 9th, 2008

This afternoon’s session was on mapping. Robert introduced the topic, explaining it is a very large and diverse field. This was reflected by the large amount of speakers and the range of subjects they covered. Because of this, and the enthusiasm of the speakers, the session ran far beyond the allotted time range.

Alex works with junXion, LiSa and two wii controllers. He got into this wanting to make something that made musical sense to him. But first he had to go the ordinary way of assigning functions to buttons. He explained how each button on the wii is mapped and configured.

After some trouble with the demo-gods, he showed his setup. He is using the setup to record his voice, extending it and working with it. He also works with prerecorded sound files. From the little snippets of performance he showed us I saw reminders to MIchel’s performances too. I am hoping to see more on Thursday.

Jo Kazuhiro / Inaudible Computing (audio input hardware for sensor data acquiition on mobile devices) http://jo.swo.jp/

Inaudible computing, an extension of physical computing.

Demo 1: push button
Mona lisa “shadow of sound”. The installation takes a picture of the person when the button is pushed and then generates the sound of the image.

Demo 2: fader controller
The SINE WAVE ORCHESTRA stay amplified. Each participant choose a sine wave frequency,

Demo 3: voltage amplitude circuit
Using USB for power.
The instrument of aeo, accelerometer, microphone, distance sensor and light bulb.

Demo 4: voltage - frequency circuit.
Using i LDR light sensor to change the frequency. Connects to iPhone. Calls it. The iphone is a device for wireless communication sensor.

Future work:
mobile phone as Dat transmitter.
voice recorder as data recorder
voice recognition as audio processing

The projects are posted to instructables so we can all have a go at making them too.

Robin demo’ed and talked about his installation: music for a prepared radio set.

It is an old fashioned radio which has been modified to analyze, modify and playing back small segments of radio. On the wall behind it is a live visualization of the sound using Processing.

The radio segments the audio in real time and analyzes it using Tristan Jehan’s program. If a segment is significant different from the sounds already in the database, then the new file is added. The interface is a traditional Bush radio and the visualization is a long wire frame cylinder that represents the samples with loudness, brightness and noisiness dictating position and angle.

Additionally by twiddling the knobs you add “heat” into the system and the “hotter the system is the more glitchy. When you leave it alone, it “cools off”.

Robin liked the original design of the radio, it is easy to fit resistors behind the dials and the final radio looks completely ordinary - only it is a radio possessed by the devil….




Robin Price - Visualization software

Tuesday, December 9th, 2008

Robin presents a performance/installation piece which maps a visualization from a live radio input database, created in real time. The input is simply the radio dial, and whenever there’s a change to the dial, the system automatically makes a new ‘entry’ (sample) in the database.

He also presents a description of the mapping strategy for the motion graphics element

  • X position proportional to loudness
  • angle theta proportional to brightness
  • radial distance from axis proportional to noisiness
  • Mode selector simply permeates the mapping between polar co-ordinate and the three spectral features
