This piece explores the potential of the built-in Apple PowerBook microphone as an expressive performance interface. Performers blow into the microphone in an attempt to control the stochastically oscillating center frequency with which a bandpass filter is applied to noise. As more "breath" is put into the laptop, the bandwidth of the filter expands, until only white noise is left.
- set volume to about 1/2 maximum to avoid excessive feedback
- ensure input is set to internal mic, output to internal speakers
- make sure nothing is plugged into the headphone jack
- files: upper.ck, downer.ck, conductor.ck
- (ahead of time) performers are designated as either uppers or downers
- The center frequency of your filter wants to go down - you must keep it up.
- The center frequency of your filter wants to go up - you must keep it down.
- Your center frequency does whatever it wants - you can only make it do so faster.
- start upper.ck, downer.ck, or conductor.ck
- blow into microphone until you're happy with where your filter is
- wait until you're no longer happy/have caught your breath
- repeat until you have no real control over the sound of your laptop
- slowly ratchet volume down
