One of the best pieces of FREEWARE. No, it is not a tool, it is a real piece of ART. Sampled sounds continuing forever without obvious repetition. Like other ART you may like it or not; it happens that I do like it. I wish there would be more exchange of Mac-Computer-Art like this one. Bravo to the artist, you made me even write my first MacUpdate comment ever. (shark)

SEELEWASCHEN is a generative sound environment which was originally composed by Karlheinz Essl for an outdoor light installation by the German artist Rainer Gottemeier. Using the sound of one single bell stroke as its basic material, the piece unfolds a rich sonic cosmos by a computer program. Taking advantage of compositional algorithms that have been developed by Karlheinz Essl since the early 1980ies, the piece is generated in realtime. It can be perceived as a sonic organism which might serve as a source for inspiration and meditation, running forever and ever...

This piece neither requires nor offers any user interaction. It runs entirely on its own, driven by its internal compositional algorithms which ensure variability and richness, even over a long time. The author does not feel obliged to make any chances to the program, but he is eager to hear your comments.

generative sound file shredder

REplay PLAYer is a computer program that de-constructs a given sound file and re-composes it by using realtime composition algorithms. It can be used as a tool to generate an infinite and every-changing sonic stream from a single sound file for artistic, compositional or mere recreational purposes. It can also be regarded as a computer based instrument for live performances, as an interactive sound installation or a generator for ambient music.
