Description:Data sonification application for scientific and artistic purposes
Abstract:Data audification (or sonification) is the representation of data and information through<BR/>sounds and melodies. Sonification can be considered as the acoustic counterpart of data graphic<BR/>visualization, a mathematical mapping of information from data sets to sounds. In the past<BR/>twenty years the word sonification has acquired a new meaning in the world of computer music,<BR/>computer science, and auditory display application development.<BR/>Data audification is currently used in several fields, for different purposes: science and<BR/>engineering, education and training, in most of the cases to provide a quick and effective data<BR/>analysis and interpretation tool. Although most data analysis techniques are exclusively visual<BR/>in nature (i.e. are based on the possibility of looking at graphical representations), data<BR/>presentation and exploration systems could benefit greatly from the addition of sonification<BR/>capabilities. In addition, sonic representations are particularly useful when dealing with<BR/>complex data or in data monitoring tasks where it is practically impossible to use the visual<BR/>inspection. More interesting and intriguing aspects of data sonification concern the possibility of<BR/>describing patterns or trends, through sound, which were hardly perceivable otherwise.<BR/>Moreover in many cases human ears are used to discover slight changes in acoustic<BR/>patterns. One example is the medicine who routinely applies acoustic data analysis when uses<BR/>the stethoscope to listen to breath noise and heart tones.
