Part of my listening experience has been a coming to terms with a certain set of musical forms that I call ‘flat’. Music in flat form means music that avoids obvious or dimensionally conjunct large-scale goals, points of arrival, ‘climaxes’, sectional boundaries, and the like, and therefore has proven difficult for many listeners. It has become clear to me that this music demands a different listening approach, one at odds with the way music is typically appreciated in the concert hall. This approach is one that composers of music in flat form can facilitate through today's computer-music resources. What I present here is a specific instance of such an approach: my composition Sand, a twenty-five-minute long work for computer-synthesised and processed sounds, was composed specifically to be experienced through a computer-music interface I built in the MAX/MSP environment. This paper explores what I mean by ‘flatness’, how I came to terms with it as a listener, and how this coming-to-terms spawned the idea and construction of the interface. I then discuss the interface itself, the process of interaction with the listener, and technical aspects of the software.

Sentire is a body–machine interface that sonifies motor behaviour in real time and a participatory, interactive performance in which two people use their physical movements to collaboratively create sound while constantly being influenced by the results. Based on our informal observation that basal social behaviours emerge during Sentire performances, the present article investigates our principal hypothesis that Sentire can foster basic mechanisms underlying non-verbal social interaction. We illustrate how coordination serves as a crucial basic mechanism for social interaction, and consider how it is addressed by various therapeutic approaches, including therapeutic use of real-time auditory feedback. Then we argue that the implementation of Sentire may be fruitful in healthcare contexts and in promoting general well-being. We describe how the Sentire system has been developed further within the scope of the research project ‘Social interaction through sound feedback–Sentire’ that combines human–computer interaction, sound design and real-world research, against the background of the relationship between sound, sociality and therapy. The question concerning how interaction is facilitated through Sentire is addressed through the first results of behavioural analysis using structured observation, which allows for a quasi-quantitative sequential analysis of interactive behaviour.

This article examines the use of Complexity Theory as an inspiration for the creation of new musical works, and highlights problems and possible solutions associated with its application as a compositional tool. In particular it explores how the philosophy behind Complexity Theory affects notions of process-based composition, indeterminacy in music and the performer/listener/environment relationship, culminating in providing a basis for the understanding of music creation as an active process within a context. The author presents one of his own sound installations, Cross-Pollination, as an example of a composition inspired and best understood from the philosophical position as described in Complexity Theory.

This article provides a close study of the University of Iowa Electronic Music Studios. The point of such a detailed account of one studio is to shed light on activity within the field of electronic music that previously did not occupy a place in the literature. Few of the studios listed in Hugh Davies’s International Electronic Music Catalog have received detailed attention. Until a wider range of close studies that pay attention to the particularities of individual cases becomes available, it will be difficult to do the comparative work necessary to gain an appropriately textured overall account of the development of electronic music in the post-war period. As these detailed studies, based largely on first-hand documentation, increase the resolution of electronic music’s history, they may highlight significant but previously unnoticed, or at least under-appreciated, patterns in the development of electronic music and act as an effective barometer of changing trends.

The advance of technology brings about modifications of style, performing techniques, music listening, and brings to us new relationships between creation, interpretation and perception. The aim of this article is to set out an approach to strategies of musical production for acoustic instruments and technological resources, describing different notions of interaction where the electroacoustic textural complexity coexists with the live processing of the instrumental source and where a goal is to work within the frame of an open and easy-to-carry-out performance structure which is friendly to the musicians, clear as a discourse and attractive to the audience.

Stochastic, unvoiced sounds are abundant in music and musical sounds. Without irregularities, the music and sounds become dull and lifeless. This paper presents work on unvoiced sounds that is believed to be useful in noise music. Several methods for obtaining a gradual change towards static white noise are presented. The random values (Dice), random events (Geiger) and random frequencies (Cymbal) noise types are shown to produce many useful sounds. Atomic noise encompasses all three noise types, while adding much more subtle variations and more life to the noise. Methods for obtaining a harmonic sound from the noise are introduced. These methods take advantage of the stochastic nature of the model, facilitating a gradual change from the stochastic sound to the noisy harmonic sound. In addition, the frozen noise repetitions are shown to produce unexpected pitch jumps with a potentially useful musical structure.

The Imaginary Space: Developing models for an emergent Malaysian/Western electroacoustic music is a Fundamental Research Grant Scheme project funded by the Malaysian government in which intercultural investigation is centred within an electroacoustic performance environment. A unique series of music outcomes and potential models reflecting a symbiosis of Malaysian and Western art music through composition and performance are emerging for instrument(s) and electronics. This paper focuses on the first and second phases of the project investigating Western flute, Malaysian serunai and pensol nose flute with electronics. Multi-stranded investigations of connections are identified within the conception, composition, realisation and reception of these works. Performer perspectives are given through two case studies. Our purpose is to illuminate understandings of intercultural connections, to begin to re-conceptualise cultural research paradigms, and to see what we can discover about performance contexts and engagement with individuals, cultures and traditions. The research is contextualised within the philosophical theories of Gadamer, Merleau-Ponty and Ingold. Investigating the role of technology in this context impels a discussion of how these elements generate a new, multifaceted environment, the space in which intercultural and performative understandings can emerge. This article focuses on how these performance contexts become a place for research and new understandings.

New interface artefacts are changing the way we interact with machines, and this is particularly important for the musical domain. Conversely, the growing do-it-yourself (DIY) culture is subverting the manufacturer–consumer model. Regarding music, software such as Pure Data and Max/MSP allows users to build their own interactive systems. These factors contribute to the emergence of new digital musical instruments (DMI). However, DMI creation still requires a strong technical background. Based on the importance of prototyping in the process of designing things, this paper presents the Sketchument, an environment devoted to help non-technical users to easily prototype DMIs, using multiple input modes and allowing the integration to other useful technologies. From a lo-fi paper prototype, to functional ones, passing through movies, questionnaires, interviews, Sketchument has been developed following the same prototyping philosophy we intend to propose to its users. The cyclic process of design–implementation-evaluation has produced valuable feedback from potential users, which has been very useful to back design choices and to push modifications.

ENACTIV is a project that addresses, explores and offers solutions for converting a performer/composer's expressive sonic and kinetic patterns into continuous variables for driving sound synthesis and processing in real-time interactive composition. The investigation is inspired by the achievements in cognitive science, in particular Umberto Maturana and Francisco Varela's Santiago Theory (1980, 1987), in which the authors explain how the process of cognition arises through ‘structural coupling’ – a mutual influence among living beings, and living beings (humans in particular) and the environment, and how this process stipulates certain patterns of organisation driving the individual's behaviour.

The project investigates how a composer/performer's cognitive archetypes, which have been developed via his or her ‘structural coupling’ with the social and natural environment and expressed through voice and unwitting hand gestures, can be associated with or ‘mapped’ onto sound synthesis and processing parameters in such a way that the system will play an active role and act reciprocally, involving a certain degree of variation and unpredictability at its output. The aim of the project is to develop a creative tool which will allow professional musicians, multi-media artists and non-expert participants to engage with multi-modal improvisation in an intuitive way.

The paper examines issues emergent from the construction of my work the bird ghost at the zaouia, which transliterates recorded experience and memory of time and place. Islamic ritual and public spaces were recorded, reworked, re-routed and re-sited in a work that references, comments upon and potentially reconfigures the Islamic sonic-social. Tracing my own stance, the paper foregrounds emergent issues in the recording and use of highly culturally freighted sounds. I trace three broad areas: 1. Sonic Orientalism – the use of sound that carries ‘Eastern’ cultural and religious significance in order to signal a certain kind of alterity; 2. The development of a compositional strategy that seeks a middle-path between acousmatic and acoustic-ecological debates; and 3. A cross-cultural comparison between modes of listening. In addition I discuss the contexts of debates on the permissibility of music within Islam, and also world-musics that trade on the romanticised alterity of sonic tourism. I draw parallels between an ‘ethically responsive sensorium’ characteristic of Islamic aural disciplines and the ‘aesthetically attuned sensorium’ engaged by sonic arts. I argue for an approach that is inclusive of the sonic and the full spectrum of vibration through ramified networks of memory and meaning.

This four-part exposition revisits Denis Smalley's concept of sound surrogacy from a critical constructive approach. In the first part, Smalley's article from 1997 serves as a point of origin for a close investigation of his concept. We examine the precise definitions and demarcations in his concepts and we attempt to systematise the model. In the second part of the investigation we attempt to solve some of the problems in Smalley's model by suggesting a new surrogacy model originating in Smalley's idea, but with a more formal structure and obvious demarcations. Having presented this new surrogacy model, with references to Georges Bataille's theories on base materialism as well as anthropological studies, we attempt to create a new order of surrogacy that in its object relation is positioned beneath Smalley's first-order surrogacy (as the remote surrogacy order is placed above the third-order surrogacy) – an impossible/paradoxical category that will be termed transgressive sound surrogacy. In the fourth part we demonstrate this new surrogacy order in a series of examples found in art and culture.

Pipe organs are complex timbral synthesisers in an early acousmatic setting, which have always accompanied the evolution of music and technology. The most recent development is digital augmentation: the organ sound is captured, transformed and then played back in real time. The present augmented organ project relies on three main aesthetic principles: microphony, fusion and instrumentality. Microphony means that sounds are captured inside the organ case, close to the pipes. Real-time audio effects are then applied to the internal sounds before they are played back over loudspeakers; the transformed sounds interact with the original sounds of the pipe organ. The fusion principle exploits the blending effect of the acoustic space surrounding the instrument; the room response transforms the sounds of many single-sound sources into a consistent and organ-typical soundscape at the listener’s position. The instrumentality principle restricts electroacoustic processing to organ sounds only, excluding non-organ sound sources or samples. This article proposes a taxonomy of musical effects. It discusses aesthetic questions concerning the perceptual fusion of acoustic and electronic sources. Both extended playing techniques and digital audio can create musical gestures that conjoin the heterogeneous sonic worlds of pipe organs and electronics. This results in a paradoxical listening experience of unity in the diversity: the music is at the same time electroacoustic and instrumental.

Many software packages for computer music encourage the composer to take either a time domain approach or a frequency domain approach. This paper examines the possibilities afforded by recent software developments of working at the intersection of these two domains. It investigates the relationship between the FOF algorithm, originally used in the CHANT program, and more traditional approaches to granular synthesis, and considers how they can be combined. The author's compositions are used as illustrations of these techniques. The significance of using the FOF algorithm in granulating sound files is explained (FOG). Methods of using and controlling the FOG unit-generator are explained. Compositional and aesthetic issues arising from working with sound at this ambiguous intersection are investigated.

We propose a conceptual framework for describing and documenting sound installations from a visitor’s point of view. In the form of a taxonomy, the framework includes four complementary perspectives: sound sources, sound design approaches, visiting modalities and visual aspects. Its elaboration was informed by a review of contemporary sound installations in Quebec as well as a literature review on conceptual and theoretical frameworks on sound art and sound installations. Compared with existing frameworks, the taxonomy is useful for describing and comparing sound installations across meaningful perspectives from a visitor’s stance. To illustrate the potential benefits of the taxonomy and the diversity of installations it can portray, we provide a comparative analysis of four contemporary sound installations from different perspectives. We conclude with the use of this taxonomy for documentation purposes.

This article explores recent theories of listening, perception and embodiment, including those by Mark Grimshaw and Tom Garner, Salomé Voegelin, and Eric Clarke, as well as consequences and possibilities arising from them in relation to field recording and soundscape art practice. These theories of listening propose auditory perception as an embodied process of engaging with and understanding lived environment. Such phenomenological listening is understood as a relational engagement with the world in motion, as movement and change, which grants access to the listener’s emerging presence, agency and place in the world. Such ideas on listening have developed concurrently with new approaches to making and presenting field recordings, with a focus on developing phonographic methods for capturing and presenting the recordist’s embodied auditory perspective. In the present study, ‘first-person’ field recording is defined as both method and culturally significant material whereby a single recordist carries, wears or remains present with a microphone, consciously and reflexively documenting their personal listening encounters. This article examines the practice of first-person field recording and considers its specific applications in a range of sound art and soundscape art examples, including work by Gabi Losoncy, Graham Lambkin, Christopher Delaurenti and Klaysstarr (the author). In the examination of these methods and works, first-person field recording is considered as a means of capturing the proximate auditory space of the recordist as a mediated ‘point of ear’, which may be embodied, inhabited, and listened through by a subsequent listener. The article concludes with a brief summary of the discussion before some closing thoughts on recording, listening and the field, on field recording as practice-research and on potential connections with other fields in which the production of virtual environments is a key focus.

In this article I explore the relationship of theories of sound reproduction formulated in the decades between the two world wars with the studio practice of Pierre Schaeffer. I argue that the 1920s–1930s was a period of significance for sound-based arts, and compare it to analogous defining moments in cinema and art photography. After examining the legacy of this period, I turn to one specific moment from Schaeffer’s early studio experiments with musique concrète in April 1948, showing how the theories of sound reproduction formed in the earlier time period informed practical decisions in Schaeffer’s working methods at a critical time when his ideas about the sound object were forming. Schaeffer’s studio practice and, to an extent, his theories of listening thus carry traces of this prior sonic culture. Considering the decisive influence of Schaeffer’s writings and teaching on later generations and developments in electroacoustic music, I speculate on the proliferation of these ideas beyond Schaeffer’s immediate circle, focusing in particular on soundscape composition. The title of this article is a reference to James Lastra’s ‘invisible auditor’, a term he coined to characterise the approach to sound reproduction discussed in this article (Lastra 2000: 159).
