[microsound] Compositions with Wavelets

[Dara Shayda]

Hello 

Feature Extraction, e.g. Trend and DeTrend, performed by Wavelets have been used to compose music made the CO2 Gas Age geological data:

The code and diagrams and data are included:

Earlier experiments with Wavelets compositions:

http://soundcloud.com/dara-o-shayda/thus-sang-the-wingless  Wavelet decomposition used to generate music from the gene expression patterns in moths and butterflies.

http://soundcloud.com/dara-o-shayda/fall-berries  Again Wavelet decomposition used to make music and beat from a photo of berries in fall time. The 'berries' formed the tune for a beat in the right channel while the edge detection of the branches generated the general melody.


The compositions are based upon Wavelet package in Mathematica 8.0, MetaSynth and Density:
