Most people are able to identify basic emotions expressed in music and experience affective reactions to music. But does music generally induce emotion? Does it elicit subjective feelings, physiological arousal, and motor reactions reliably in different individuals? In this interdisciplinary study, measurement of skin conductance, facial muscle activity,(More)
Music can arouse ecstatic "chill" experiences defined as "goose pimples" and as "shivers down the spine." We recorded chills both via subjects' self-reports and physiological reactions, finding that they do not occur in a reflex-like manner, but as a result of attentive, experienced, and conscious musical enjoyment.
Today's efficient audio codecs for low bitrate application scenarios often rely on parametric coding of the upper frequency band portion of a signal while the lower frequency band portion of the same is conveyed by a waveform preserving coding method. At the decoder, the upper frequency signal is approximated from the lower frequency data using the upper(More)
An adequate study of emotions in music and film should be based on the real-time measurement of self-reported data using a continuous-response method. The recording system discussed in this article reflects two important aspects of such research: First, for a better comparison of results, experimental and technical standards for continuous measurement(More)
Bandwidth extension (BWE) is an important parametric technique applied by modern audio coders in order to achieve efficient data rate compression at low bitrates. The perceptual quality of BWE enhanced signals is, however, often hampered by artifacts caused by inharmonicity. We propose hence a bandwidth extension method that avoids inharmonicity, and, at(More)
After 18 ICAD conferences, Auditory Display has become a mature research community. However, a robust evaluation and scientific comparison of sonification methods is often neglected by auditory display researchers. In the last ICAD 2012 conference, only one paper out of 53 makes a statistical comparison of several sonification methods and still no(More)
The aim of this study was to investigate whether listening to music in a group setting influenced the emotion felt by the listeners. We hypothesized that individuals hearing music in a group would experience more intense emotions than the same individuals hearing the same music on their own. The emotional reactions to 10 musical excerpts (previously shown(More)
Modern audio coding technologies apply methods of bandwidth extension (BWE) to efficiently represent audio data at low bitrates. An established method is the well-known spectral band replication (SBR) that is part of MPEG High Efficiency Advanced Audio Coding (HE-AAC). However, if the signal features a distinct harmonic spectral structure, the use of these(More)
Route guidance systems are used every day by both, sighted and visually impaired people. Systems, such as those built into cars and smart phones, usually using speech to direct the user towards their desired location. Sounds other than functional and speech sounds can, however, be used for directing people in distinct directions. The present paper compares(More)
