  1. STEREO Sonification Project D. Bithell, R. Morales, L. M. Peticolas, N. Craig Space Sciences Laboratory (SSL) Center for New Music and Audio Technologies (CNMAT) University of California in Berkeley STEREO Meeting Berkeley, CA - December 18, 2004

  2. Aims of the Project - Science: create sonic representations of data and find new approaches to displaying multi-channel, multi-source data (like STEREO) Education: create new methods of introducing and interacting with key concepts in science and music Music: create tools for creative exploration of sound using solar data as a rich generative material

  3. Examples Science: A computer realization of carbon flux Music: An excerpt from Roberto Morales’ orchestral composition “Turning Point” incorporating scaled Helios data

  4. • Sonification - mapping data into sound How closely does the sonification represent the physical reality of the data? -There is always a degrees of abstraction and arbitrariness in the mapping -Issues of musical perception and cognition -The “Art of Mapping”

  5. Max/MSP Programming Environment Graphical object oriented programming language designed for real-time processing and coordination of musical and multimedia events. Auroral Chorus AKR SEP Electrons, Iron, Oxygen Ions

  6. Description of the Data Structure (Spectrogram Color Analysis) Using image file types (.jpeg, .gif, etc.): -RGB and HSL color values are used to scale parameters of sonic processing -Easy to manage data in multiple formats -Able to automatically reconfigure processing based on the number of bins (y-axis) and length of the data (x-axis)

  7. Types of Processing: "Physical Modeling” •Frequency Scaling of Sine Waves •Amplitude Scaling of a Harmonic Spectrum "Arbitrary Modeling” •Granular Synthesis •Frequency Modulation synthesis
