Andante

What used to be the UltraWaterExtraordinaryGigaGroup is now:

Andante

Andante: IntraSpectrum Sound Walk

The old title actually was a funny way of explaining all the different technologies that were being used to record the sounds. 3 different routes we agreed on beingĀ  remarkable for a visit in Porto were tracked by the GPS to be drawn in a audible map. The audio map contains a broad range of frequencies captured. We used a Gigahertz Sniffer to retrieve cellphones, bluetooth and wi-fi broadcastings (from 1 to 5.4 GH), than an ultrasound receiver (20 to 100KH), followed by binaural recordings and finally hydrophones for underwater and contact microphones for low vibrations.The special hidden channel of the mix was recorded with the banana mic, for the bio-protein frequencies.

Through MaxMSP we programmed the wii-controller to access this different dimensions of our routes through Porto, that can be followed in a googlemaps application, where you can go back and forth, accellerate, navigate the layers and jump through the different routes.
