Public performances of computer music employing high-density loudspeaker arrays 
can convey powerful spatial experiences that are not available in home stereo 
or headphone listening. However, the development and dissemination of spatial 
aspects of computer music have been hindered by a stereo bias that has pervaded 
both commercial music distribution formats and institutional practice. The 
vinyl record, cassette, MiniDisc, and CD all enforce the stereo format. Even 
today, most festivals of computer music that present works in even modest 
multichannel formats such as octophonic, still limit musical submissions to the 
stereo format.

Despite the above-mentioned problems of dissemination, spatial aspects have 
long been an area of focus for electronic and computer musicians. Early 
examples of electronic music projected on high-density loudspeaker arrays 
(HDLAs), which we define here as systems addressing 24 or more independent 
loudspeakers, include music for the Phillips Pavilion at the Brussels World’s 
Fair in 1958, and music for the spherical auditorium at the Osaka Expo in 1970. 
Both the Phillips Pavilion and the spherical auditorium were temporary 
structures, dismantled shortly after the performance event. Unlike most 
contemporary computer music research, which can be pursued on personal 
computers more or less anywhere, work with HDLAs still challenges researchers 
with the basic problem of finding a viable workspace.

Fortunately, an increasing number of computer music research spaces housing 
HDLAs have become available, the majority of which were built in the 21st 
century. A few pioneering music festivals have recently emerged such as BEAST 
FEaST at Birmingham University, and inSONIC at ZKM, where music is selected for 
its suitability for performance over resident HDLAs. The Spatial Music Workshop 
at Virginia Tech invites participants to develop computer music for a 
138-channel HDLA. The transition from distribution of music on a physical 
medium to distribution by digital download allows for complete freedom of the 
choice of format. While commercial net labels still favor stereo, this is no 
longer an inherent limitation of the medium. Informal distribution of computer 
music in upwards of 100 channels is already taking place between institutions 
that support musical performance on HDLAs. As the means for composing with 
HDLAs and disseminating the resulting music increases, it seems appropriate to 
present the most promising directions for this growing area of computer music 
research.

This call for submissions for a special issue of the Computer Music Journal 
focuses on recent developments and future prospects of computer music composed 
for high-density loudspeaker arrays.

Relevant topics include, but are not limited to:

* New methodologies for composing music using HDLAs
* Strategies for presenting computer music in a variety of HDLA systems
* Aesthetic approaches to spatialization for HDLAs
* Cognitive aspects of listener apprehension of HDLA-based music
* Sonification using HDLAs
* Reports on the design and use of mobile HDLA systems
* Reports on recent developments in wave field synthesis
* Room acoustics simulations using HDLAs
* Speaker design for HDLAs
* Software design for HDLAs

In addition to papers, we invite brief statements on the nature and prospects 
of computer music for HDLAs. We welcome a wide variety of aesthetic, technical, 
sociological, and other perspectives. A selection of these statements will be 
published in a special Forum section.

Deadline for paper submission is January 30, 2016. The issue will appear in 
2016.

Submissions should follow all CMJ author guidelines 
(http://www.mitpressjournals.org/page/sub/comj 
<http://www.mitpressjournals.org/page/sub/comj>),except that manuscripts should 
not be submitted online at cmjdb.com <http://cmjdb.com/>. Instead, submissions 
and queries should be addressed to
<[email protected] <mailto:[email protected]>>, with the subject starting with [CMJ 
HDLA Computer Music].
