Chaos Music - The Final Piece

Chaos music is a composition based on my research and programming of the functions documented in my previous post. The piece uses the output data from the chaotic functions to drive musical synthesis with the built in functions of CLM, more explanation about methodology can be found in the attached report.

Algorithmic Comp. Piece 2 Research - Choas Functions

For my final year piece iv been researching choatic functions and non-linear maps. Below is a selection of function iv ported into Lisp. Each function outputs a text file that can be imported into most graphing software (the corresponding pictures were all produced with MATLAB). I intend to implement these functions and use there output to drive a piece of music.

The Logistic Equation


(with-open-file (*standard-output* "logistic.txt" :direction :output
:if-exists :supersede)
(let* ((x 0.5)
(r-env '(0 1 1000 4.0))
(r 0.0))


(loop for i below 1000 do
(setf r (envelope-interp i r-env)
x (* r (* x (- 1 x))))
(format t "~D ~D~%" r x)
)))

Algorithmic Composition with Common Lisp Music - Piece 1

This composition was used as an inital exploration into the world of Lisp and Common Lisp Music 4 (CLM). It experiemtned with using the builtin instruments as well as instruments provided by the course lecturer. It takes loose inspiration from a piece by John Chowning with more explanation in the report. All samples used are referenced from within the source file and can be downloaded from www.freesound.org
