Tara Rodgers – sand, snow, breeze (2012)

A series of audio-visual compositions using digital photographs and computer-generated noise to represent landscapes and weather events. RGB color data from the photographs are converted into filtered brown, white, and pink noise using GraphicConverter and the programming environment SuperCollider. A touch of postproduction is done with an FMR Really Nice Compressor and a Moog MF-101 Lowpass Filter. Sound selections and data mapping choices are crafted to evoke the place and experience in the photographs.

Brown Noise / Sand (2005/2012)
1 digital image, custom software, stereo audio, 15+ min.

BrownNoise_Sand.jpg

A single digital photograph of a rock on the beach, taken on Block Island, RI, ca. March 2005; reduced in size to 40×30 pixels. RGB color data from each pixel are used to shape a granular synth that processes and filters a segment of brown noise. Pixel data are read left to right and top to bottom across the image, with resulting sounds randomly panned in stereo. A small area of sand is expanded to 16 minutes of granulated brown noise.

White Noise / Snowstorm (2008)
10 digital images, custom software, stereo audio, 10 min.
