Dissociated Studio Dissociated Studio takes a piece of audio, segments it into (by default) 0.1 second segments, computes a matrix indicating how similar each segment is to each other segment, and then plays the piece through, occasionally skipping from one segment to another similar segment, while displaying various either informative or spiffy-looking (or both!) displays. Emacspeak Emacspeak is a speech interface that allows visually impaired users to interact independently and efficiently with the computer. Audio formatting --a technique pioneered by AsTeR-- and full support for W3C's Aural CSS (ACSS) allows Emacspeak to produce rich aural presentations of electronic information.

Emu EMU is a collection of software tools for the creation, manipulation and analysis of speech databases. At the core of EMU is a database search engine which allows the researcher to find various speech segments based on the sequential and hierarchical structure of the utterances in which they occur. EMU includes an interactive labeller which can display spectrograms and other speech waveforms, and which allows the creation of hierarchical, as well as sequential, labels for a speech utterance. FreeWheeling FreeWheeling is a live looping instrument built for improvisation. Using a keyboard or a MIDI controller, it allows to build and control repetitive patterns from a live audio stream.

IMPSKE IMSKPE is a graphical user interface for the formantsynthesis algorithms. It uses GTK2, has wav export, and can read and write par files. InSpect InSpect is a sound analysis program, made in order to look at the inner structures of sounds. The purpose of InSpect is to analyze a sound given its expression in the temporal model (audio signal amplitude versus time). The result of the analysis is a sound represented in a spectral model, which is mainly the sinusoids+noise model defined by Xavier Serra and Julius O. Smith. Lack Of Invention LOI is a realtime sound processing tool. You can use it as a software guitar pedal or a voice distorter or for any other realtime sound processing purposes you can think of.

MARSYAS MusicAl Research System for Analysis and Synthesis is a software framework. It is a collection of classes written in C++ and JAVA for various sound analysis and synthesis tasks. MuSE Streamer MuSE is an application for the mixing, encoding, and network streaming of sound: it can mix up to 6 encoded audio bitstreams (from files or network, mp3 or ogg) plus a souncard input signal, the resulting stream can be played locally on the sound card and/or encoded at different bitrates, recorded to harddisk and/or streamed to the net. When sent to a server, the resulting audio can be listened through the net by a vast number of players available on different operating systems. Musica Musica is a sound and music synthesis package for Mathematica, providing advanced facilities for composition, analysis and playback.

The DaisyPlayer Project DaisyPlayer is a program for playing Digital Talking Books (DTB). Its main focus is to make a library with a small, easy-to-use API, making it easy for other developers to write their own daisy players without having much knowledge about the Daisy format and standards. A console and a GUI front-end are available for this library to demonstrate how it can be used in practice and for those who just need a simple daisy player.
