Computer Music Programming Language

CIOS Audio Core is the infrastructure and subsystem in Collective Intelligence Operation System. It is a cross platforms audio abstract interface, supports including Mac OS X, Linux, Android, iPhone OS and Windows 7.

Unlike conventional audio players, ARITA aims to help music lovers to keep their precious collections well organized and tidy. Therefore it takes a different approach to arranging audio files. They must be emplaced into libraries: 'archives' or 'cuesheets'. Archive - compressionless container like CPIO. Instead of tags for description of tracks, a plain XML/YAML file is placed alongside each archive. Rather than embedding cover art in every track, put a single image next to a library. TIFF supports multipage docs, so scans of covers/discs can be packed together in one file. ARITA will locate and display the said file, allowing you to view all pages. Optional 'signature' files can be created to keep checksums of tracks, so you may ask ARITA to verify them and make sure nothing is damaged due to a sudden failure of HDD/SSD. As for 'cuesheets': tracks are merged into a single continuous audio file and a supplementary text file, which provides information on where tracks start and end.

cl-pcp is a collection of Common Lisp CFFI bindings for Pango, Cairo, and PixBuf from the GTK+ (Gimp Tool Kit) Project. This is meant as a lightweight, general solution for developing graphical/text based applications in Common Lisp.

Mapserver is a GIS application offering a MapScript library for scripting applications. CL-MAPSCRIPT offers Common Lisp bindings for the MapScript library based on the CFFI glue.

DACML stands for Digital Audio and Computer Music Language. It is implemented as a Common Lisp library and low level C routines for efficiency. The aim is to apply functional paradigm to Computer Music composition. Licensed under GPL v. 3 or later.

Incudine is a Music/DSP programming environment for Common Lisp. It provides a mechanism for defining primitive unit generators on-the-fly and scheduling sample accurate callbacks.

Jeszra is a visual designtool, which combines 2D- vector graphics and GUI design. Jeszra is written in Tcl/Tk and creates reusable code for: * Tcl, Ruby, Lisp and Python. * DocBook based reference pages. * SVG import and export.

CM-ETF is an extension to the Common Music composition environment, which allows for output of musical data in ETF "Engima Transportable File" format, readable by the popular commercial musical notation software, Finale. Requires CM and lisp.

Implementation of raytracer with its prototype written in LISP. Goals: lisp knowledge.

RMG: a Random Music Generator written in Common Lisp using the Common Music library, producing MIDI as output. RMG differs from other random music generators in that it is actually intended to sound good, "good" being defined as "better than bad techno".
