In this paper, we present and discuss S-notation for sample-based music, and particularly for DJ scratching and turntablism. Sonnenfeld developed S-notation based on his Theory of Motion where scratch music is seen as constructions of concurrent musical gestures (motion parameters), and not only turntable actions. The detailed symbolic notation was inspired by traditional musical notation, and among its advantages it covers current musical needs, it can be read and played live in performance, it provides a tool for composers to convey musical ideas, it can be expanded towards new styles and techniques, and it is generalizable to other types of sample-based music. In addition to motion parameters, the new notation system involves an analysis of the sampled sound. Finally, S-notation is also applicable for documenting and for teaching situations.

In this paper, a study on sonification of manual wheelchair movements is presented. The aim was to contribute to both rehabilitation contexts and in wheelchair sports contexts, by providing meaningful auditory feedback for training of manual wheelchair operation. A mapping approach was used where key parameters of manual wheelchair maneuvering were directly mapped to different sound models. The system was evaluated with a qualitative approach in experiments. The results indicate that there is promise in utilizing sonification for training of manual wheelchair operation but that the approach of direct sonification, as opposed to sonification of the deviation from a predefined goal, was not fully successful. Participants reported that there was a clear connection between their wheelchair operation and the auditory feedback, which indicates the possibility of using the system in some, but not all, wheelchair training contexts.

This commentary to Greasley and Prior's paper "Mixtapes and turntablism: DJs' perspective on musical shape" extends the findings of the study by looking at the turntablism perspective. First, a general discussion on the study's method and background is given. Then, the role of turntables as musical instruments in creating musical shape is outlined. Finally, some relationships between turntablism techniques, expressive performances and musical shape are presented. In general, the findings in the study support previously published studies in this insufficiently researched area.

In this paper we introduce an application for tablet devices with Android operating system called The Music Puzzle.This work is part of an ongoing projectcalled The Soundparkï¿œUsing modern smartphones to create interactive listening experiences for hearing impaired. In the Soundpark, we intend to provide different experimental applications for interacting with sound. The aim of the presented study was to create interactive and game-inspired listening experiences for persons with hearing impairmens (and possibly using hearing aids or having cochlea implants). Audio-based programs constitute a significant part of the Android market, but the scopes of existing applications are limited. Modern smart devices open up new possibilities both in terms of usingexternal information as input and providing real-time audio feedback to the user, and the Music Puzzle has a novel approach that explores the new possibilities.

This paper describes a system for accommodating active listening for persons with hearing aids or cochlear implants, with a special focus on children at an early stage of cognitive development and with additional physical disabilities. A system called the Soundscraper is proposed and consists of a software part in Pure data and a hardware part using an Arduino microcontroller with a combination of sensors. For both the software and hardware development it was important to always ensure that the system was flexible enough to cater for the very different conditions that are characteristic of the intended user group. The Soundscraper has been tested with 25 children with good results. An increased attention span was reported, as well as positively surprising reactions from children where the caregivers were unsure whether they could hear at all. The sound synthesis methods, the gesture sensors and the employed parameter mapping were all simple, but they provided a controllable and sufficiently complex sound environment even with limited interaction. A possible future outcome of the application is the adoption of long-time analysis of sound preferences as opposed to traditional audiological investigations.

This paper introduces a database of sound-based applications running on the Android mobile platform. The longterm objective is to provide a state-of-the-art of mobile applications dealing with sound and music interaction. After exposing the method used to build up and maintain the database using a non-hierarchical structure based on tags, we present a classification according to various categories of applications, and we conduct a preliminary analysis of the repartition of these categories reflecting the current state of the database.

The use of technology in artistic contexts presents interesting challenges regarding the processes in which engineers, artists and performers work together. The artistic intent and goals of the participants are relevant both when shaping the development practice, and in defining and refining the role of technology in practice. In this paper we present strategies for structuring the development process, based on iterative design and participatory design. The concepts are described in theory and examples are given of how they have been successfully applied. The cases make heavy use of different types of prototyping and this practice is also discussed. The development cases all relate to a single artifact, a gestural voice processing instrument called The Throat. This artifact has been in use since it was developed, and from that experience, three cases are presented. The focus of these cases is on how artistic vision through practice can recontextualize technology, and, without rebuilding it, redefine it and give it a new role to play.
