Open Source BSD Sound Synthesis Software

A programmable audio generator intended as an aural aid to meditation, implementing the binaural beat principle as described in Gerald Oster's Oct. 1973 Scientific American article "Auditory Beats in the Brain."

The Pure Data (short Pd) project on SourceForge unifies the extensions (or externals) written for the Pure Data Graphical Computer Music System written by Miller Puckette with contributions from many others.

A Sequenced Binaural Wave Generator for Linux+Windows. May be used to generate sounds that entrain the brain's waves to oscillate at selected frequencies to aid in relaxation, lucid dreaming, meditation, clear thought, out-of-body experiences + more

N.B. SuperCollider is now hosted at GitHub, and the most recent versions can be downloaded from there. http://supercollider.github.io A real time audio synthesis engine, and an object-oriented programming language specialised for music. SuperCollider was created in 1996 by James McCartney, now (since version 3) released as free software.

Epulse is a signal generator that can produce pulses, sine, triangular and rectangular waves with an unlimited level of modulations. It can be used in electronics to create test signals, or to make simple audio effects.

Musica is a sound and music synthesis package for Mathematica, providing advanced facilities for composition, analysis and playback.

"CAGE", the Computer Audio Garden in Eclipse, is to be an Eclipse-based, Java and XML workbench, for the computer music composer. It will use the Rich Client Platform to provide a basic backbone framework, enabling existing computer music tools to be p

SoftMusic is a program that creates music based on a random generator and various restrictive algorithms. It can be used for quickly creating ambient musical backdrops, cyclic arpeggios that can be used in techno songs, or just plain strange music.

Sound Orgy is a suite of command line tools for the purpose of sound production and modification as well other misc sound related functons. Sound Orgy consists of components which use command line piping to connect to each other much like patch cords.

Nowadays the idea of a music of the spheres, or a cosmic music that descends from the planets seems more like poetic philosophy than anything scientific. However, when the scientist Kepler discovered special principles about planetary motion, he also reconsidered the music. Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity. The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a Java Virtual Machine (Rev 1.5 or greater). JAVA 2, system independent. Purpose:to encourage research in harmony in astronomy, math and music. Obstacles:math, DSP/synthesis, networks, astronomy. Features:audio, database, graphics Technologies: Telnet, .WAV audio, oggvorbis, other audio

qliss3d renders 3d-Lissajous-figures (figures made of a different sine functions for each dimension) with a Qt interface. You can look at the figures from any viewing position you like and even "listen" to the sound of the figures.

Realtime audio synthesis library using the flexible unit generator architechture. Many uses: music, scientific sonification, generic audio processing. Multithread abilities, extensible synth framework. Similar to modular analog synths.
