Open Source C 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."

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.

A real-time software synthesizer based on the SoundFont 2 specifications. It can be used for live audio synthesis of MIDI events or for rendering MIDI files to disk, using SoundFont instruments. It can also be embedded in other applications. This is not a application with a graphical user interface, however there are several GUI applications which utilize FluidSynth.

Bristol is synth emulation package for a diverse range of vintage synthesisers, electric pianos and organs. The application consists of a multithreaded audio synthesizer and a user interface called brighton.

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.

A cross-platform patch editor for the E-MU Proteus 2000 sample-based synthesizer family. prodatum is free software.

DSSI is an audio plugin API for software instruments (soft synths) and effects. It is based on the LADSPA plugin API, the ALSA sequencer event types, and OSC (Open Sound Control) communications with custom GUIs.

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

Snd is a sound editor.

A SoundFont editor and other software for editing, managing and sharing sample based MIDI instrument files for computer music composition. Support for other formats is planned.

The No Budget Orchestra Plugins are a collection of virtual (software) musical instruments. comprising a full, classical orchestra There are flute, piccolo, oboe, bassoon, clarinet, violin, viola, cello, contrabass, trumpet, trombone, tuba, french horn, and various percussion sections. The various sections include articulations. For example, the violin section can play legato, pizzicato, staccato, and tremulo. There are subgroups as well, for example Violins I and II. The plugins are in LV2 (Linux) format for use in Ardour, Muse, QTractoor, etc. They are available in 2 formats; a collection of LV2 plugins, and a collection of linux executables. The plugins can be loaded into a host program such as Ardour, Muse, QTractor, etc. The executables are standalone versions that contain both the samples, and the engine that plays them.

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.

Convert text to International Morse Code. Input is ASCII text. Output can be: - . -..- - on the console, raw 8bit PCM suitable for piping to /dev/audio, .wav files or even (mp3|ogg). Good for headlines on your MP3 player or code practice.

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.

Advanced GTK+ Sequencer is intended to use for music composition. It features a piano roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output panel. It's designed to be highly configurable, you may add effects to its effect chain, add or remove audio channels/pads. You may set up a fully functional network of engines, therefore exists a link editor for linking audio lines. In conjunction with ags you need a realtime kernel and alsa support. `ags` uses conditional locks to keep several threads in sync that's why you need at least a preemptible kernel.

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.

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.

x0xb0x is an open source 'acid' bassline synthesizer with sequencer

TiMidity++ Windows Synthesizer (TWSYNTH) extended TiMidity++ to read midi inputs. CAUTION !! TWSYNTH proj. is obsolute. TWSYNTH sources are sucessfully included Timidity++. see http://sourceforge.net/projects/timidity

SPU2ghz is a SPU2 plugin for the PlayStation 2 emulator PCSX2 (and other that use the same plugin API). cdvdGigaherz is a CD/DVD plugin using win32 IoCtl calls to access real drives.

NEZplug is multi-console(NES, SMS, MSX, TG16...) sound subsystem emulator.

Standalone, LV2 and VST instruments & effects generating weird sounds, noises and glitches, for experimental music. Heavily inspired by the Futurist musician Luigi Russolo, the aim of this project is to create new instruments for the new century.

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.

ppc is an E-MU Planet Phatt, Orbit, Carnaval remote and SysEx-editor written in C/GTK+-2. You can control all global- and all preset-parameters and create new presets.
