Open Source 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."

A multi-platform software synthesiser emulating (somewhat inaccurately) pre-GM MIDI devices such as the Roland MT-32, CM-32L, CM-64 and LAPC-I. In no way endorsed by or affiliated with Roland Corp. Source hosted at: http://www.github.com/munt/

The Analysis & Resynthesis Sound Spectrograph analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.

Standing Wave 3 is an ActionScript 3 audio library that provides high-level control over the Flash Player’s SampleDataEvent API for streaming audio output. It builds on the foundation of Standing Wave 2 but has been extensively refactored, with its core sample storage and manipulation routines rewritten using Adobe Alchemy for significant performance improvements. Originally derived from the audio engine used in the Noteflight Score Editor, the library allows developers to combine and chain together audio sources, filters, and sequences to create dynamic, real-time sound experiences. Supported audio sources include MP3s, WAV files, and algorithmic generators, while filters enable effects such as echo, equalization, and envelope shaping. The system is flexible enough to handle complex timing sequences of audio, making it suitable for advanced audio applications or interactive projects.

didgmo is a software for DIDGeridoo sound MOdeling. didgmo is capable of predicting the sound characteristica of a didgeridoo by providing its inner geometry. didgmo uses the method of acoustic transmission line modeling.

Just download the above zip file, extract it and then open the respective index.html file on your favourite internet browser and follow the instructions shown.

CWStudio is a portable almost library-independent and computationally efficient generator of CW signals for telegraphy training purposes. It can create a sound with maximum similarity to the real air, simulating many difficulties.

The Tibetan and Himalayan Library has several open-sourced tools for inputting, manipulating, translating, and transcribing Tibetan-language text, audio, and video. We aim to make using a computer easier for Himalayan peoples and scholars.

The CLUNK C++ library provides support for real-time 3D(binaural) sound generation. It puts virtually no limitations on the developer; people who have experienced working with other solutions (such as SDL_Mixer or Creative OpenAL) will respect this advan

BeatBox is a Java application in which users use a 16x16 grid of checkboxes to create a beat with various percussion instruments. Beats can be saved and loaded easily. The entire application is as intuitive and user-friendly as possible.

Loris is a library for sound analysis, synthesis, and morphing, developed by Kelly Fitz and Lippold Haken at the CERL Sound Group. Loris includes a C++ class library, Python module, C-linkable interface, command line utilities, and documentation.

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

The Python Sound Project aims to develop a productive community around Python, Csound and other synthesis engines as tools for algorithmic composition of electroacoustic music.

A unique desktop music composing application for PC/Mac/Linux/Android with a tracker style interface and a simple modular Java plugin based design allowing rapid improvement and endless expansion.

Portable command line utility for encoding and recording audio signals (chirps) to set the speed, incline, and resistance functions of iFit technology equipped exercise machines. Writes generated settings signals to music file format.

RasmusDSP is an embeddable Audio/MIDI processor. It contains various filters and generators (including SoundFont 2.0 compatible synthesizer). Has a script interpreter which is used to describe instruments, route Audio/MIDI signal between processor units.

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

A morse code trainer for Gnome. Teaches morse code using the Koch method. Requires GTK+ and Pulseaudio.

The Analysis & Reconstruction Sound Engine analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.

Artificial Intelligence (AI) evolves musical instruments you play with the mouse from small blocks of Java code that operate on numbers, each block designed to keep all numbers in range -1 to 1 if they started in that range, and combinations of these evolved codes running 44100 times per second for high quality 44.1 khz audio. You can also write the Java code into its window. Uses Javassist internal compiler on the new Java code assembled by renaming variables to overlap eachother and reordering, copying, and removing blocks of code. Listen to the recorded music in files section of sourceforge or try it for yourself. This branched into my other projects: GigaLineCompile, JSelfModify, JSoundCard, and Human AI Net as I got more into the AI and systems side of things and explored vision research as a better user interface to network minds together through the Internet. Someday I will bring it all together in a shared space on the Internet.
