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.

Nyquist is a language for sound synthesis and music composition. It is implemented in C and C++ and runs on Win32, OSX, and Linux. Nyquist combines a powerful functional programming style with efficient signal-processing primitives. Nyquist is also embedded as a scripting language in Audacity.

Snd is a sound editor.

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

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

30 modules, 300+ Synthedit prefabs ranging from subcontrol circuits to synths, fsu effects, drum sequencers, near complete copy/paste/save/load system for xox style patterns. 2 complete vst effects, and one vst synth.

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.

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

Tao is a software package for sound synthesis using physical models. It provides a virtual acoustic material constructed from masses and springs which can be used as the basis for building quite complex virtual musical instruments.

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.

OSW is a graphical programming environment for real-time music and audio applications. Users connect objects called transforms to form programs called patches. OSW currently runs on Windows, Linux, Mac OS X and SGI platforms.

The MusicKit & SndKit is an object-oriented software system for building music, sound, signal processing & MIDI applications. The distribution is a comprehensive package that includes on-line documentation, code examples, utilities, applications & scores

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

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/

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.

MaxxHi5 was focusing originally a VST Plug-in's software, Since then decided turned it into a community as well "MaxxHi5", and made many other types of plug-ins and multimedia software, as stated at the beginning of the project.

Phonolith is a software instrument for AmigaOS 4, which plays sampled waveforms. It's usable with Horny and other CAMD based sequencers, or just a connected MIDI keyboard.

Create your own rythms. Make entertaining musical bases combining as you like six different electronic drum samples. You can use your mouse, touchscreen or keyboard (Q, W, A, S, Z, X). Also available for Android and Windows Phone. Portable. No installation required.

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

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).

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.

Soundbench is high-quality GPL-licensed software synthesizer written in C++/Qt that is meant to work across all major platforms (though especially most common Linux distributions). Soundbench follows a development philosophy that emphasizes getting everything stable before adding new features. Soundbench is meant to be usable by anyone who wishes to produce music, whether they are hobbyists, professional musicians, or experienced sound designers. The program is currently in Beta, meaning that it is ready for some simple music production, however is not yet completely stable or complete.

Steel is a cross-platform package for using common text-to-speech (speech synthesis) engines in Python. Steel currently supports the following TTS software: - Microsoft Speech API 5 (SAPI5) - eSpeak - NS Speech Synthesis - FreeTTS Documentation: http://sourceforge.net/p/steeltts/wiki/ Bug Tracker: http://sourceforge.net/p/steeltts/tickets/ If you are interested in contributing to the Steel TTS codebase, or would like to make a feature-request, please contact the lead developer, Jasper Danielson, at jrd4@rice.edu.
