I believe in art and technology. And I believe in a nature of civilization. And the artifice of nature. And in the nature of technology. I believe that man is a part of nature, and whatever man does, it is natural. The divide between natural and artificial seems to be artificial, and if there is no natural division between kinds, they have to be of the same (natural) kind. Thus artificial is a subset of natural. |

The Forest Translatoris connected to a tree in a Closed Ecologic Circuit, which is built after instructions from an American middle school science project. It consists of three layers; groundwater, decomposition, and terrestrial. Each layer is contained in a glass vessel, in which I have drilled holes to facilitate the circulation of water and air between the layers. They are sealed of from the outside with aquarium-silicone. At the top there is a lamp, a speaker, and galvanic skin response meter (GSR). The lamp provides the light for the terrestrial layer, the speaker is for the plants to hear the sounds they utter, and the GSR is connected to electrodes which measures the fluctuations of voltage in the tree. The biomass is collected from the forests around Oslo.The GSR is built using Michael Sungs design. On each board there are four GSR's which each measures one branch on the tree. The board also has an Arduino board, which is used to communicate with the computer. The computer is running Xubuntu linux (http://www.xubuntu.org/) and the graphical programming environment PureData (PD). In PD I have built a package which maps the signals from the trees to a system for additive formant synthesis, which is the computationally cheapest way to do speech in a computer. The theory is that one can build any sound the human speech organ can produce by controlling fundamental frequency, voicing and noise levels of a sawtooth-signal. I originally wished to use the PRAAT system which models the sounds by parameters based on the human speech organs, but, considering my limited time, I was not able enough a C-programmer to rewrite the code for realtime processing. Hopefully, some day I will find the time to build a PD external from it. |
