Alphabet Soup is a project which attempts to determine a number of things about the shapes of letters in several different writing systems. First, it hypothesizes a set of basic building blocks that all letters are built up from. Second, it hypothesizes a set of rules, a grammar or syntax, which defines how those pieces combine to make different letters. It can generate individual letters, randomize letters in an input string to create weird but readable text, or generate random strings of symbols.
PyMP3Cut is a Python command line tool designed to cut huge (> 100MB) MP3 files at high speed without requiring the extra disk space and processing time usually needed by visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything. It reads and cuts simultaneously according to the autodetected MP3 frame rate and a timeline passed as a command line argument. It doesn't currently deal with Variable Bit Rate (VBR) MP3 files, though.
XELand generates night landscapes as stereo pairs for cross-eye viewing. Currently it uses two map generation methods (plus some variations). Generated height maps are seamless and can be saved as PNG images. The program requires only JDK 1.5 or above, and is very easy to use. To take full advantage of XEland you should learn cross-eye viewing.
Autocomp is an accompaniment generator for Perl and Csound. It takes as input a text file containing chord changes, plus time signature and bpm information, and outputs a Csound .sco file containing a simple arrangement of those changes. A sample Csound .orc file containing a bass instrument, a selection of keyboard instruments, and a small sample-based drumkit is provided.
Pysco is a neat utility for CSound. It generates CSound note events and saves to a score file, with unlimited separate output time-streams ("tracks"), unlimited simultaneous different tempos (each track can have its own tempo, including independent accelerandos and ritards), unlimited named "chunks" of events, and many more functions to provid automatic time updating so that the user doesn't have to count beats all the time. It also selects ranges of musical chunks by beat value.
Kandid is a system to evolve graphics. Graphics, in Kandid, are not drawn by hand. Instead, new forms can be found using genetic algorithms. To achieve this aim Kandid simulates evolution using sexual reproduction and mutation. But there is no fitness function inside the program. Only the user can decide what images are interesting. Populations and genes can be stored in XML format. Image calculation is based on Lisp-like expressions, Lindenmayer Systems, Iterated Function Systems, Linear Cellular Automata, Voroni diagrams, and layered textures or isosurfaces rendered by the Persistence of Vision raytracer.
Pymprovisator is a program for jazz musicians. Jazz music is based on improvisation and this program is intended to help musicians to improvise. The user sets the song parameters and the program generates a MIDI file with an adequate accompaniment. It emulates the program Band in a Box from PG Music. You can think of it as the electronic version of the books/CD from Jamey Aebersold.
Grammidity is a Java based framework for evolutionary programming based on grammars. It can be used to evolve solutions to problems, or to evolve "objects" under user control. It has a limitless range of possible applications. This program has been tested on sample projects generating 3D objects and imitation plants.
