Frequency Band Collector is a work born inside the master sound studies of the UdK university of Berlin, that focuses on the variety of environments and daily situations experienced through the sense of hearing.
The system gets an audio input that is analysed into ten frequency bands. After that it identifies what is the sound with the highest volume and, this particular frequency, causes a water drop into a container connected to a specific band.
Over a extensive enough distance of time, is possible to see on the computer screen the number of times, during the input sounds, that interested a specific frequency band, but not only.
The water containers, instead, corresponding to the various frequency bands, transform this informations into pictures in real time.
In addition, the importance of Frequency Band Collector consists in the fact that it stores the input data creating an informative memory about the frequencies which are present in the environment where the system is situated. It’s a sort of puzzle made of sounds, that is able to provide a sound picture of the environment.
