In the auditory domain a chunk is seen as a segment of sound. This work first investigates theories of chunks from cognitive science and musicology. We define the chunk as a closed entity of a certain size and with ...

This function creates, when divided by n -1, what is here called the primety measure, which is a measure of how close to being a prime number n is. The quality of a number sequence can be determined using the primety, which is further generalised to real numbers through the use of real numbered Farey sequences. Ambiguous and interesting results are obtained in this process; for instance it seems that all integers approach full primety when investigated in the real domain. The corresponding numerical sequences are furthermore shown to have interesting artistic properties. In particular the fractal behaviour is interesting. To further investigate fractal ambiguity, common fractals are extended with random elements, which render softer or more varied shapes. , treating signal processing applied to music with a physical and perceptual point-of-view. This mainly involved classification, and modelling of musical sounds. He has been involved in synthesisers for children, state of the art next generation effect processors and signal processing in music informatics. His current research topic is signal processing with musical applications, and related fields, including perception, psychoacoustics, physical models and expression of music. He has chaired more than eight major conferences, been the editor of many books and conference proceedings and published more than 200 papers, and he currently holds a position at the Institute of Architecture, Design and Media Technology, Aalborg University Esbjerg as an Associate Professor. This paper is a revised and expanded version of a paper entitled 'Numerical investigation of the primety of real numbers' presented at Second International Conference, ArtsIT 2011, Esbjerg, Denmark, December 2011.

The article is about how experiential knowledge that the craftsmen gains in a direct physical and tactile interaction with a responding material can be transformed and utilised in the use of digital technologies. SoundShaping is based on a generic audio feature extraction system and the principal component analysis to ensure that the pertinent information in the voice is used. Moreover, 3D shape is created using simple geometric rules. The shape is output to a 3D printer to make ceramic results. The system demonstrates the close connection between digital technology and craft practice. Several experiments and reflections demonstrate the validity of this work.

As examples, three projects within NNIMIPA involving performance interaction examine the role of audio and gestures in emotional musical expression using motion capture, the visual and auditive cues musicians provide each other in an ensemble when rehearsing, and the decision processes involved when a musician coordinates with other musicians. These projects seek to combine and compare intuitions derived from low-tech instructional music workshops that rely heavily on the use of whole-body gestures with the insights provided by high-tech studies and formal logic models of the performing musician, not only with respect to the sound, but also with regard to the movements of the performer and the mechanisms of group coordination.

Megame uses letters and words to amuse, train and assess memory capacity. Based on memory research, the main parameters of the working memory have been identified and some improvement possibilities are presented. While it is not clear that the working memory in itself can be improved, other cognitive functions are identified that may be improved while playing Megame. Other uses of Megame include spelling and vocabulary training and learning modality assessment. Megame is written in Python using an agile and iterative approach, taking advantage from rapid prototyping and allowing for user-driven development.
