We uploaded a little video documenting ANDANTE project…

ANDANTE : Multiangled Soundwalking in Porto
Summer School in Sound and Music Computing & SID Training School on Interactions with Environmental Sounds
Casa Da Música , Porto, Portugal
July 18-21, 2009
By Niels Böttche, Reinhard Gupfinger, Vanessa de Michelis and Pablo Sanz Almoguera.
With the help and support of the tutors Stephan Baumann (DKFI) and Bram de Jong (Freesound Project).
Four dimensions of the soundscape of Porto were registered along three chosen routes within the city.
The audible range was recorded in binaural stereo together with ultrasonic frequencies, electromagnetic emissions, underwater sound and solid vibrations.
The gps coordinates of the walks were traced into a map which can be navigated with a Wii controller. It allows to change between the four sound layers, jump between the routes, move backward and forward and change the speed of the journey.
The summer school ended, but as Fabien said yesterday let’s keep in touch through the blog. I hope you had a nice time and you learnt a lot during these days.
Some pictures of Portification (formally known as Sonifying Porto).
The prototype version consisted of 5 FSRs and 2 ribbon sensors that were glued on an alternative map of Porto and a webcam that was placed above the map.
For each FSR the audience could trigger 3 sounds (recorded at the same location) depending on the amount of pressure executed. For each ribbon sensor 5 sounds could be triggered depending on the position of the finger on the ribbon.
The webcam tracked the movement from the audience when they moved from one sensor to another and the sound evolved depending on that position. Unfortunately the light conditions were not optimal and the tracking could not be optimised.
We will continue to develop this prototype and further explore interface possibilities and the real-time modification of the sounds.

What used to be the UltraWaterExtraordinaryGigaGroup is now:
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 being 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.
