Audio games: investigation of the potential through prototype development

This article discusses the potential of audio games based on the evaluation of three projects: a story-driven audio role-playing game (RPG), an interactive audiobook with RPG elements, and a set of casual sound-based games. The potential is understood, both in popularity and playability terms. The first factor is connected to the degree of players’ interest, while the second one to the degree of their engagement in sound-based game worlds. Although presented projects are embedded within the landscape of past and contemporary audio games and gaming platforms, the authors reach into the near future, concluding with possible development directions for this non-visual interactive entertainment.

Playing with sound and gesture in digital audio games

This article introduces the genre of a digital audio game and discusses selected play interaction solutions implemented in the Audio Game Hub, a prototype designed and evaluated in the years 2014 and 2015 at the Gamification Lab at Leuphana University Lüneburg.1 The Audio Game Hub constitutes a set of familiar playful activities (aiming at a target, reflex-based reacting to sound signals, labyrinth exploration) and casual games (e.g. Tetris, Memory) adapted to the digital medium and converted into the audio sphere, where the player is guided predominantly or solely by sound. The authors will discuss the design questions raised at early stages of the project, and confront them with the results of user experience testing performed on two groups of sighted and one group of visually impaired gamers.

The Auld Alliance: Organ music from Scotland and France.

CD recording of the Rieger organ of St Giles' Cathedral Edinburgh, performed by Michael Harris, with music from Scottish composers, and composers based in Scotland, as well as French organ music from the seventeenth to twentieth centuries.

Lie detection and children: Impact of the mode of presentation

Although a great deal of research has examined lie-detection among adults, little research has examined the differences between audio and visual mediums for deception among children. In the current study participants were presented (n = 42) with recordings of four children, each describing his/her experience of getting glasses. Two of the accounts were truthful, two were fabricated. Half of the participants were presented with videos, half were presented with audio-recordings. Following the presentation of each recording, participants responded to questions regarding the truthfulness of each child’s account. Results showed that when evaluating truth-tellers, participants’ lie-detection accuracy was significantly greater than chance. Within the video condition, non-parents were shown to report significantly more lie-related cues than parents. Several deception cues were shown to be related to lie-detection accuracy.

Class-D audio amplifiers with negative feedback

There are many different designs for audio amplifiers. Class-D, or switching, amplifiers generate their output signal in the form of a high-frequency square wave of variable duty cycle (ratio of on time to off time). The square-wave nature of the output allows a particularly efficient output stage, with minimal losses. The output is ultimately filtered to remove components of the spectrum above the audio range. Mathematical models are derived here for a variety of related class-D amplifier designs that use negative feedback. These models use an asymptotic expansion in powers of a small parameter related to the ratio of typical audio frequencies to the switching frequency to develop a power series for the output component in the audio spectrum. These models confirm that there is a form of distortion intrinsic to such amplifier designs. The models also explain why two approaches used commercially succeed in largely eliminating this distortion; a new means of overcoming the intrinsic distortion is revealed by the analysis.

kidipedia - Einsatz eines (audio-)visuellen Bildungsmediums im geographisch-orientierten Sachunterricht

Bei der Vermittlung geographischer Kompetenzen im Sachunterricht der Grundschule stellen Karten und andere visuelle Medien wichtige Lernmedien dar (vgl. Haubrich 2006, 174ff.). Der vorliegende Beitrag beschäftigt sich mit der Einbindung von audiovisuellen Medien in die Onlineplattform kidipedia. Dabei wird zunächst ein Überblick über aktuelle Möglichkeiten der Einbindung multimedialer Inhalte gegeben, bevor Erweiterungsmöglichkeiten mit dem Fokus auf geographische Inhalte skizziert werden.

Os efeitos da música na audição

Introdução: A música tem um papel importante na sociedade, assim como na audição. Pode, quando em excesso e a elevadas intensidades, causar danos no sistema auditivo; também, permite melhorar o desempenho do processamento auditivo tanto no desenvolvimento de capacidades como no abrandamento dos efeitos do envelhecimento no Sistema Nervoso Central. Objectivo: Este estudo teve como objectivo verificar se existem diferenças nos resultados do Teste Padrão de Frequência (TPF), dos Limiares Auditivos por via aérea e das Otoemissões Acústicas por Produtos de Distorção (OEAPD) entre os grupos controlo e de músicos, entre ouvidos nestes dois grupos e verificar se no grupo de músicos existem diferenças nos testes quanto aos ensaios e se se encontram correlações entre estes testes e variáveis, como o número de anos de prática, a classe de instrumentos tocada, o tempo de exposição semanal à prática musical, a idade de início da prática. Metodologia: Foram comparados dois grupos: grupo de músicos de música clássica do Conservatório de Música de Coimbra e grupo controlo de indivíduos sem prática musical. Resultados: Encontraram-se diferenças estatisticamente significativas entre os dois grupos, para todos os testes. Entre ouvidos, encontraram-se para os músicos diferenças estatisticamente significativas nos Limiares Auditivos e nas OEAPD, e nas OEAPD para o grupo controlo. Nos músicos encontraram-se correlações entre os anos de prática e o TPF e os Limiares Auditivos; e entre a idade de início da prática musical e o TPF. Conclusões: Perante os resultados pode-se concluir que a prática musical pode trazer aspectos positivos, melhorando as capacidades temporais do processamento auditivo e podendo assim privilegiar a facilidade de comunicação em situações difíceis, podendo ainda evitar-se os aspectos negativos tais como a perda auditiva.

Capturing and indexing rehearsals: the design and usage of a digital archive of performing arts

Preserving the cultural heritage of the performing arts raises difficult and sensitive issues, as each performance is unique by nature and the juxtaposition between the performers and the audience cannot be easily recorded. In this paper, we report on an experimental research project to preserve another aspect of the performing arts—the history of their rehearsals. We have specifically designed non-intrusive video recording and on-site documentation techniques to make this process transparent to the creative crew, and have developed a complete workflow to publish the recorded video data and their corresponding meta-data online as Open Data using state-of-the-art audio and video processing to maximize non-linear navigation and hypervideo linking. The resulting open archive is made publicly available to researchers and amateurs alike and offers a unique account of the inner workings of the worlds of theater and opera.

Comunicación audio visual y creatividad como recurso para producir nuevas formas de periodismo cultural local: estudio de caso, la tradición artesanal en el cantón Cuenca

No existe en Cuenca un proyecto de investigación periodística y de producción audiovisual que indague, recopile y presente información sobre aquellas profesiones tradicionales heredadas a través del tiempo y que poco a poco se van perdiendo con miras a extinguirse completamente. Este proyecto, de cierta manera, puede ser innovador, ya que involucra dos áreas: comunicación audiovisual y redacción dentro del periodismo. Se involucran por el hecho de presentar información relevante, a través de un producto final, visual y escrito, que enseñe de quéforma estas profesiones son desarrolladas por diferentes actores humanos, sus contextos y sus procesos, con la intención de servir de apoyo investigativo cultural en el ámbito local y nacional.
