Open Source Windows Sound Synthesis Software

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.

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.

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.

Project that aims converting a text page directly into MP3 or other audio format using the MBrola libraries

Party Pad is a live sound processing application which allows a set of effects to be controlled by the position and pressure of a finger on a Synaptics Touchpad (found on Dell and IBM laptops, for example). http://www.youtube.com/watch?v=c2lcA6SSfXY

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

SilenceVST is an extensible, open-source language for programming music and sound on Windows. SilenceVST consists of a set of Python extensions and a custom Python shell that runs either standalone, or as a VST plugin.

The project is about porting selected (open source) music-, and audio software to latest compilers and platforms...

hscratch is a simple command-line tool to produce scratch sounds from a given phonogramme offline coded in Haskell. Currently, it lacks all that command-line sugar like '-v' and '-h'. Working prototype, still to be developed and improved.

Replacement for the Java Media Framework (JMF), allowing you to transport not only audio and video. In extention a modular software synthesizer designer/sequencer sharing local hardware over the internet.
