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."

FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications and has reached widespread distribution. FluidSynth itself does not have a graphical user interface, but due to its powerful API several applications utilize it and it has even found its way onto embedded systems and is used in some mobile apps.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

Snd is a sound editor.

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

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

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.

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.

Industrializer is a program for generating percussion sounds for musical purposes. This program is great for generating new techno and industrial sounds. It also can produce chimes, bubbles, gongs, hammer hits on different materials and so on.

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.
