    International audienceRecent technological advances, such as increased CPU/GPU processing speed, along with the miniaturization of devices and sensors, have created new possibilities for integrating immersive technologies in music and performance art. Virtual and Augmented Reality (VR/AR) have become increasingly interesting as mobile device platforms, such as up-to-date smartphones, with necessary CPU resources entered the consumer market. In combination with recent web technologies, any mobile device can simply connect with a browser to a local server to access the latest technology. The web platform also eases the integration of collabora-tive situated media in participatory artwork. In this paper , we present the interactive music improvisation piece 'Border,' premiered in 2018 at the Beyond Festival at the Center for Art and Media Karlsruhe (ZKM). This piece explores the interaction between a performer and the audience using web-based applications-including AR, real-time 3D audio/video streaming, advanced web audio, and gesture-controlled virtual instruments-on smart mobile devices

    hpDJ: An automated DJ with floorshow feedback

    No full text
    Many radio stations and nightclubs employ Disk-Jockeys (DJs) to provide a continuous uninterrupted stream or “mix” of dance music, built from a sequence of individual song-tracks. In the last decade, commercial pre-recorded compilation CDs of DJ mixes have become a growth market. DJs exercise skill in deciding an appropriate sequence of tracks and in mixing 'seamlessly' from one track to the next. Online access to large-scale archives of digitized music via automated music information retrieval systems offers users the possibility of discovering many songs they like, but the majority of consumers are unlikely to want to learn the DJ skills of sequencing and mixing. This paper describes hpDJ, an automatic method by which compilations of dance-music can be sequenced and seamlessly mixed by computer, with minimal user involvement. The user may specify a selection of tracks, and may give a qualitative indication of the type of mix required. The resultant mix can be presented as a continuous single digital audio file, whether for burning to CD, or for play-out from a personal playback device such as an iPod, or for play-out to rooms full of dancers in a nightclub. Results from an early version of this system have been tested on an audience of patrons in a London nightclub, with very favourable results. Subsequent to that experiment, we designed technologies which allow the hpDJ system to monitor the responses of crowds of dancers/listeners, so that hpDJ can dynamically react to those responses from the crowd. The initial intention was that hpDJ would monitor the crowd’s reaction to the song-track currently being played, and use that response to guide its selection of subsequent song-tracks tracks in the mix. In that version, it’s assumed that all the song-tracks existed in some archive or library of pre-recorded files. However, once reliable crowd-monitoring technology is available, it becomes possible to use the crowd-response data to dynamically “remix” existing song-tracks (i.e, alter the track in some way, tailoring it to the response of the crowd) and even to dynamically “compose” new song-tracks suited to that crowd. Thus, the music played by hpDJ to any particular crowd of listeners on any particular night becomes a direct function of that particular crowd’s particular responses on that particular night. On a different night, the same crowd of people might react in a different way, leading hpDJ to create different music. Thus, the music composed and played by hpDJ could be viewed as an “emergent” property of the dynamic interaction between the computer system and the crowd, and the crowd could then be viewed as having collectively collaborated on composing the music that was played on that night. This en masse collective composition raises some interesting legal issues regarding the ownership of the composition (i.e.: who, exactly, is the author of the work?), but revenue-generating businesses can nevertheless plausibly be built from such technologies

    Straddling the intersection

    Get PDF
    Music technology straddles the intersection between art and science and presents those who choose to work within its sphere with many practical challenges as well as creative possibilities. The paper focuses on four main areas: secondary education, higher education, practice and research and finally collaboration. The paper emphasises the importance of collaboration in tackling the challenges of interdisciplinarity and in influencing future technological developments

    Functionality and history of electronics in regards to the performance practice of the following works: Temazcal (1984), Javier Álvarez, and Memory Palace (2012), Christopher Cerrone

    Master's Project (M.Mu.) University of Alaska Fairbanks, 2016The Electroacoustic pieces; Temazcal (1984), by Javier Alvarez (b.1956), and Memory Palace (2012) by Christopher Cerrone (b.1984), each employ different types of electronic technologies in their realization through performance. This paper will discuss the origin and history of the technology applied respectively in the works. I will examine the role of percussion within the works, specifically in regards to learning and problem solving through technological challenges in order to effectively perform the compositions. By looking at Temazcal and Memory Palace through the context of their historical significance as electroacoustic works, the inherent functionality of the technology employed in each, and the resultant performance practices that have subsequently developed, a greater musical appreciation and understanding of electroacoustic works, in general, is possible
