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

Fourier Analysis and MATLAB - Phase Vocoder

My first go at using MATLAB as a language was to build a phase vocoder with variable Q (below 1.5 works best) and create a GUI for easier use. It contains two methods of stretching Both versions of the source code are attached (GUI and non-GUI). Isnt the fastest implementation so I would advise against trying to stretch large files. There are two algorithums included for stretching, the first use Overlap add of windows to create the strech where as the other takes into account phase modifications

Computer Programming for Music Technology - Quadraphonic Delay In C and Max/Msp

The final piece of a course in C and its uses in building Max/Msp objects was to design and code a quadraphonic (four tap) delay in C for use as a Max/Msp object. The delay takes an incoming mono signal and allows the user to set four delay times which correspond to the the four outputs.

Real Time Systems Piece 2 - PS3 Dualshock 3 as a Performance Controller

Building on Submission 1 this performance piece use the PS3 Dualshock 3 controller as its interface. It takes full advantage of the built in tilt sensors as well as pressure triggers, analogue sticks D-pad and buttons. Functionality is best achieved through the Motion In Joy driver and getting the data through Max's hi object
