Open Source Sound Synthesis Software

eGuideDog project develops free software for the blind. Currently, we focus on WebSpeech, Ekho TTS and WebAnywhere.

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.

As a library of classes for generating and manipulating music and sound, jMusic provides a solid framework for computer assisted composition in Java. jMusic has a music data structure based upon note/sound events and methods for modifying and structu

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

RetroCode(tm) is a universal mobile content converter. RetroCode(tm) is able to read and write most common sample based ringtone formats including meta-data. Formats: SMAF (MA2,MA3,MA5,MA7), RMF, MFM, CMX, QCP, AMR (NB,WB), AAC, MP3, OGG, SWF, RA, WAV

CECILIA is an environment for music and signal-processing that uses Csound as its underlying audio processing engine. One can think of CECILIA as a completely programmable sound-processing tool, with real-time interactive processing on soundfiles or live

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.

AdPlug is a cross-platform OPL2 audio player library. AdPlug plays music, originally composed for the AdLib (OPL2) audio board, on top of an OPL2 emulator or by using the real hardware. There are multiple player software interfaces available.

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.

Spectral Orchestrator--A software tool for musicians and composers that creates harmonies/orchestrations from digitally recorded sound files. Currently compiles and runs in Linux and Mac OS X (and eventually Windows/Cygwin).

Cow is a waveform editor. It generates sounds out of graphs for amplitude and frequency. A handy graphical user interface (using Qt) helps you drawing these graphs.

Csound is a sound and music synthesis system, providing facilities for composition and performance over a wide range of platforms. It is not restricted to any style of music, having been used for many years in at least classical, pop, techno, ambient. Csound is now hosted at https://github.com/csound Binary and source-code releases: http://csound.github.io/download.html Mailing lists are hosted by HEAnet at https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND and https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND-DEV Archives: mail lists at http://dream.cs.bath.ac.uk/Csound-archive releases: http://dream.cs.bath.ac.uk/Csound-archive/OldReleases/

A free, portable software synthesiser program: allows you to build a synthesiser by linking plugin modules.

A general tool for creating and processing sound in a general manner. The plug-in system makes it possible to create a complete software studio with all kinds of cool little boxes.

siN is an experimental sound synthesis tool. It is designed for composers of experimental music. The aim of the siN project is to compose tools such that alternatives are present which facilitate desirable music.

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.
