Azide compounds have vast applications in military and civilian industries. Some of their applications include use in drug or drug intermediate production, macro cyclic polymer production through click reaction, automobile airbag production, energetic binders such as GAP, oxidizer, plasticizer and burning rate control additive in solid composite propellants. Due to the wide range of appli...
Corpus-based concatenative synthesis (CBCS) builds on a large database of segmented and descriptor-analysed sounds that are selected and played according to proximity to a target position in the descriptor space. This can be seen as a content-based extension to granular synthesis providing direct access to specific sound characteristics in real-time. The aim of the article is to show how CBCS s...
This paper presents the results from a qualitative case study of an auditory version of the game Towers of Hanoi. The goal of this study was to explore qualitative aspects of auditory direct manipulation and the subjective experience from playing the game. The results show that it is important to provide a way of focusing in the auditory space. Articulatory directness was also an important issu...
