As part of the seminar "The world as a soundmemory: Electro-acoustic composition with HansTutschku" at the Institute for Musicology of the University of Cologne with Dr. Marcus Erbe, this study was done similar to the compositional practice as Hans Tutschku recorded sounds himself. The participants took the opportunity with Tascam stereo recording devices of the surrounding region and the university itself to examine its range of sounds and collected avariety of shots.
This experiment only uses concrete and no synthetic sounds that provide the basis for transformation and processing. The transformations are usually based on transposition and changes in the speed. Some filters and effects like delay for example are used.
E.g. the following output sounds are used:
Road noise (Universitätsstr.)
The knock on a metal plate
The whirring of a tape
Interference sounds of a mobile phone
Some fragments of speech
egg Slicer
A broken sink
smack sounds
key clashes
A literal and musical quotation by Karlheinz Stockhausen
and more.

Le minuit de la foi - Morgendämmerung (7020)
Le minuit de la foi (The midnight of the faith) (2014) for electronic and concrete sounds, around selected sentences by Edith Stein recorded by German actress Gisela Claudius. New work from Jean-Claude Eloy, a long piece under the power of expanded sounds and sacred words.
Le minuit de la foi is a double album, each CD of which forms a stand-alone entity. Each CD can therefore be listened to separetly. However, you do need to listen to the full album for it to become meaningful through its complementary balances, and to grasp its very essence.

The Gates of H. is generated out of a 120 second sample containing a folk song sung by a female choir. Algorithmical structures are applied to the sound by changing pitch and time-position to portions of the source sample so that a granular-synthesis structure is generated. The idea of modifying a sound image in this way is to apply a new structure to an already existing image and place it like a mask above the sound, while this mask is in time and pitch instead of space and colour.
The result is a sound which exposes either the algorithmical structure while the sound image becomes unrecognisable or the sound image when the duration of the grains is long enough and the pitch is not extremly modified. I was especially interested into the transient states of the grain, where dependant of the lenght of the sounds timbre or voices become audible: The listener seem to hear events which create an association to a human voice but it does not really sound like a voice. This keeps the perceptive process of the listener toggling between the context and the content of the sound grains.
The tension between the source sample and the algorithms gives a lyrical or a dramatical effect to the resulting sound while the recognisable voice images seem to create surrealistic scenes with strong associative power. Since I passed the Rodin Sculpture la porte de l enfer the gates of hell nearly every day on my way to the studio in Stanford a connection between the bronce plastic and my piece was unconciously drawn.
The sound processing techniques are restricted to sampling-rate conversion and pointer operations. The piece was created exclusively digitaly on the NeXT-Net of the CCRMA using Bill Schottstaedts Common Lisp Music synthesis language, Rick Taubes Common Music score/composition language and Paul Lanskis RT mixing program. It won the Prix Ars Electronica 1994. The piece was made possible by a scholarship of the DAAD by the German Government.
Ludger Bruemmer lives in Essen, Germany and teaches currently at the electronic studio of the Folkwang Hochschule Essen and at the Studio of the Technical University of Berlin. He holds a masters in psychology/sociology and a masters in composition, which he studied with Nicolaus A. Huber and Dirk Reith in Essen. Mr Bruemmer worked with the Nederlands Danstheater in Den Haag and choreographer Susanne Linke and the Susanne Linke group for 2 internatiolly performed dance productions. He also worked with several solo dancers for solo productions. For his works he was awarded with the Busoni Award/Berlin, the Folkwang Award/Essen and the WDR broadcasting Award/Cologne, Prix Ars Electronica Austria and got a honorable mentioning at the Luigi Russolo Award/Italy and Stockholm Award 1995. His pieces are performed in South America, US, Europe, Asia and Mid East.
