Live demo of sonifying global CO₂ level

Here is a simple ChucK program that performs the above dataset with a sine wave. Click "Start" to run the live ChucK code. Try out some live edits by modifying something in the live code block and then clicking "Replace" to hear your changes. Suggestions include, for example, lowering the 100::ms interval to speed up the tempo.

  // change timbre
  SawOsc osc => dac; 
  // change pitch range
  osc.freq(vals[i]*1000+500); 
  // change tempo
  10::ms => now; 

  50::ms => now; // start after 50ms
  SinOsc osc => dac; // play the data with a sine wave
  for (0 => int i; i < nVals; i++) {
    osc.freq(vals[i]*1000+200); // data values in range 0 - 1
    100::ms => now;
  }
