One of the most demanding tasks of electro-acoustic music has always been
composition of space.
While the basic principles of periphonic sound (re)production have been known for decades,
these approaches could not be used in ``live processing''-environments due to the
lack of computational power which is needed to do
multi-channel signal-processing,
the basis of any periphonic production and reproduction, in real-time.
In the last few years, the computer industry has reached a point,
where multi-channel digital sound processing can be done on the basis of
commercial personal computers.
A system, that can be used for live-rendering of periphonic sources in concert-situation
as well as for post-production, has been developed:
abcde, an Ambisonic Based Coding and Decoding Environment.
