Augmented audification

Abstract

We present a sonification method that blends between audification and auditory graphs which we call ”Augmented Audification”. It is based on a combination of single-side-band modulation and a pitch modulation of the original data stream. Benefits include the flexible adjustment of the sonification’s frequency range to the human hearing range and the possibility to interactively zoom into the data set at any scale. The paper introduces the method by three examples: deterministic harmonic complexes, random signal analysis, and seismology.
