Abstract
This presentation proposes a method to represent an extended archiving of
acousmatic works, based on the example of Hans Tutschku's recent piece
Distance Liquide. Firstly, Hans Tutschku's Distance Liquide archive is pre-
sented. Secondly, the method is explained. And thirdly, we show how to
apply this method to the selected work.
1 { Acousmatic works are dened as pure recorded (tape) music, that
is without live instrument or electronic interaction. Usually, the archive of
those pieces consist on a single nal tape and its security copies, nowadays
a single digital le. It appears to us that it is very important to archive
more elements of an acousmatic piece, i.e. the nal mixing session and their
variant, and furthermore the source elements. This is proposed mainly to
ensure the possibility of enhancing the sound quality in further times.
2 { The method we use to describe an acousmatic archive is a le-based
method: the les give us a rst group of elements that we can link. These
les have to be collected, selected, and classied. Then, they can be used as
a rst version of each level of information (e.g. main creation
ow, additional
information about the main creation
ow, documents and rights). This rst
version can be completed later and we can also look for new les.
3 { This method was applied to the selected work Distance Liquide. The
rst step of the method was interesting regarding many points, especially:
some documents were missing, it was hard to know the status of some les,
and dening levels of information was very helpful to work eciently in the
following steps. The result is promising. It gives us a life-cycle that we will
reuse for other acousmatic works.
