An audio feedback system that iteratively uses a room as a sound filter can be an artistic medium generating fascinating sounds. In this system, the room is not the only component acting as a filter. The sound system component, i.e. the speaker and microphone, also can have a sizeable impact on the sound in each iteration. To make sure the relative influence of the room on the sound is revealed and not masked by the audio system, the author proposes using a common calibration method at the end of each iteration.

The artistic techniques of mimesis—the representation of reality in art—make it possible to “render the unreal familiar or the real strangely unfamiliar.” The author, a composer and intermedia artist, uses mimetic techniques in acoustic composition, video art and field recording to reimagine everyday experience, as in his multimedia piece Landscape: Home.

The author presents a novel compositional framework to guide designing interplay between moving listeners and sound objects in space. Demonstrated by a case study of interactive octophonic installation, the presented framework offers new ways to articulate and analyze artistic interplay using real-world location context as a spatial composition canvas.

Respire is an immersive art piece that brings together three components: an immersive virtual reality (VR) environment, embodied interaction (via a breathing sensor) and a musical agent system to generate unique experiences of augmented breathing. The breathing sensor controls the user’s vertical elevation of the point of view under and over the virtual ocean. The frequency and patterns of breathing data guide the arousal of the musical agent, and the waviness of a virtual ocean in the environment.

The Blued Trees project is a transdisciplinary thought experiment, physically manifested across miles of the North American continent. It melds ideas about music, acoustics, art and environmental policy. Hundreds of GPS-located individual trees in the path of proposed natural gas pipelines were painted with a sine wave sigil. Each “treenote” contributed to an aerially perceivable composition employing the local terrain. The score is the formal skeleton for systemic changes challenging several laws.

This article elaborates on the new media musical project The Matter of the Soul: its background, theoretical approach, methods and realization. The Matter of the Soul is a musical, sculptural and performance work. It aims to engender empathy in humans with the process of dispersal and transformation in the Arctic amid the climate crisis. The work draws an analogy between human migration, the movement of water from ice to ocean in the Arctic and changing identity online.

This article discusses Heavy Metal, an interactive installation work by Nigel Helyer. The authors situate this work within the context of a collaboration among environmental science, art and media theory, a three-year research project entitled When Science Meets Art: An Environmental Portrait of the Shoalhaven River Valley.
