Self-Organizing Map for Reaktor
This is a little program for creating Self-Organizing Maps that help to arrange sample-grain-positions topographically by characteristics of their respective frequency spectra.
an audio-sample is split into little pieces (grains) and a two-dimensional index-map is created where grains with similar frequency-characteristics are near to each other. the resulting map can be exported to the Reaktor table-format to drive a grain-sampler or something like that within NI’s Reaktor.
the program (win32), the open-source code (cross-platform c++) and full documentation along with a sample ensemble can be downloaded from the Reaktor User-Library
