Sonification of Emotion : Strategies for Continuous Display of Arousal and Valence
2013
Sonification is an interdisciplinary field of research broadly interested in the use of sound to convey information. A fundamental attribute of sound is its ability to evoke emotion, but the display of emotion as a continuous data type has not yet received adequate attention. This paper motivates the use of sonification for display of emotion in affective computing, and as a means of targeting mechanisms of emotion elicitation in music. Environmental sound and music are presented as two possible sources for non-verbal auditory emotion elicitation, each with specific determinants and available features. The review concludes that the auditory-cognitive mechanisms of brain-stem reflex and emot…
Emotional Data in Music Performance : Two Audio Environments for the Emotional Imaging Composer
2013
Technologies capable of automatically sensing and recognizing emotion are becoming increasingly prevalent in performance and compositional practice. Though these technologies are complex and diverse, we present a typology that draws on similarities with computational systems for expressive music performance. This typology provides a framework to present results from the development of two audio environments for the Emotional Imaging Composer, a commercial product for realtime arousal/valence recognition that uses signals from the autonomic nervous system. In the first environment, a spectral delay processor for live vocal performance uses the performer's emotional state to interpolate betwe…
