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.

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.

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.

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

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.

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

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.

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.

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

Snd is a sound editor.

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.

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.

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.

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.

eChanter is an Open Source electronic bagpipe project, based on the Arduino platform, using capacitive touch sensors, with polyphonic wavetable synthesis PCM audio at 8KHz. See Files for the development version, eChanter v3.0.

Text-to-Speech conversor for Basque and Spanish. It includes linguistic processing and built voices for the languages aforementioned. Its acoustic engine is based on hts_engine and it uses a high quality vocoder called AhoCoder. Developed by Aholab Signal Processing Laboratory: https://aholab.ehu.es/aholab/ http://aholab.ehu.es/ahocoder/

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.

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

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.

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.

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.

A fast, accurate, and flexible "shoebox" room acoustics simulator that supports both specular and diffuse reflections.
