Extase

Another experiment in using physical modelling sound synthesis. This time the model used is a system of 4 inter-connected plates. The plates are excited using variable length sequences of pre-filtered digital impulses. The frequency of the impulses is set equal to one of the first twelve mode frequencies of the first two plates. These sounds are then layered to create chords and hence the harmonic structure of the piece is derived entirely from the spectral content of the first two plates.

All sound synthesis done in SuperCollider, all numerical math done with the help of Python (using Numpy and Scipy). This is a stereo reduction of the original 24-channel version.

Made with SuperCollider, Python and a little help from Audacity.

Extase 3 (Version)

Another piece (stereo version) made with a self-build physical modelling library for SuperCollider and Python. The model used for the sounds consists of two plates which are connected to each other through 6 stiff strings of different physical proportions. 

The different spectral content throughout the piece is achieved by exciting different strings and plates and, by picking up the response of all individual objects at different locations along their surface.

The excitation signals are made up from different types of filtered noise and impulses (FOF synthesis) and an attempt has been made to model / compose different types of environmental sound scenes purely using sound synthesis methods.

All sound synthesis and sequencing done in SuperCollider using Unit Lib and my custom physical modelling lib.
