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.

Qsynth is a fluidsynth GUI front-end application, written in C++ around the Qt framework, using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynths.

Frinika is a free, complete music workstation software for Linux, Windows, Mac OSX and other operating systems running Java. It features sequencer, soft-synths, realtime effects and audio recording.

This software integrates a small, specialized synthesizer and vocal processor. It can be used to learn Byzantine Church singing. You can play from the keyboard, mouse or touch screen. MIDI input is also available. Voice functions include: pitch highlighting, synthesizer control by voice, pitch correction and voice-to-ison conversion. On the screen there are labels with symbols of Byzantine notes. There is a metronome. The program is oriented on the Chrysanthos tuning of the diatonic scale: 9/8 - 12/11 - 88/81. The octave is divided into 17 (or 19) non-equal parts, it allows you to get all the Byzantine modes.

SPTK is a suite of speech signal processing tools for UNIX environments, e.g., LPC analysis, PARCOR analysis, LSP analysis, PARCOR synthesis filter, LSP synthesis filter, vector quantization techniques, and other extended versions of them.

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

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.

This kangaroo-themed program allows the user to create their own music and sound effects, effectively from scratch. There are two variants of the program: Kangas Sound Editor which requires MySQL for its database, and Kangas Sound Editor QI which does not (it uses an internal database - HSQLDB - instead). Kangas Sound Editor (QI) uses a system of boxes or cells, which are placed by the user onto a timeline using drag-and-drop, and which represent entities such as chords, repetition, and individual sounds or notes. The program's database allows the user to create and store harmonics, used for constructing melodic instruments, and anti-harmonics, which are used for constructing percussion instruments. Users can collaborate with and build on the work of others via an XML import/export facility.

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.

A VST plugin designed to allow manipulation of two buffers in a number of ways. Could be considered as a cross between a simplistic wavetable synthesizer and GRM Tools' Freeze plugin.

jVSTwRapper allows you to develop VST (2.4), Audio Unit (AU) and LADSPA compatible audio plugins and virtual instruments plus user interfaces (Swing) with the Java programming language on Windows, Linux and Mac OSX. 5 demo plugins (+src) are included.

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.

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.

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

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.

Extension plugins for the SuperCollider3 audio synthesis server (see <http://supercollider.github.io/>). These third-party plugins provide additional synthesis, analysis, and other capabilities for the sound server.

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.
