Research Goals in Digital Music: A Ten Year View
Research goals for the next ten years lie at the heart of this Roadmap. The roadmap
has identified six research goals which each unite a number of complementary research
activities. These documents draw together current state-of-the-art research in
digital music and outline future directions in key areas of research.
Machine listening involves the development of artificial devices and algorithms
capable of analysing audio signals in such a way as to extract meaningful information
about the music content and sound quality.
While computer systems have been designed to allow composers and musicians to
create musical compositions and performances using sound synthesis, digital signal
processing algorithms and other musical tools, there is insufficient understanding
of the human factors associated with the creative process.
New technologies have changed the way many people use, access and listen to music.
Developments in access, searching, archiving and rights management will be important
to the future development of music exploitation and dissemination.
Music created using computer technology has become a key expression of 21st century
culture. Technology has created new possibilities for composition and performance
innovation for many creative musicians. Many new possibilities are emerging.
The control of audio and musical processes can often require cumbersome manipulation
of numeric parameters, to adjust computer algorithms or devices. An integration
of knowledge from human sciences, acoustics and signal processing could result
in powerful and complex audio systems controlled by simple descriptors.
Among the most critical processes in the chain of digital music production and
its reception are those of sound recording and reproduction. These are well advanced
but there are still many potential developments in transducer technology, and
in the capture and reproduction of sound fields.
