Heilan is a standalone OpenGL X3D browser designed for audio work. It features a low latency Ambisonic audio engine, allowing for full 3D sound with virtually any configuration of speakers. It also has full Open Sound Control support, allowing scenes to be manipulated in realtime.
Calf is a set of audio effect plugins. Several plugins are provided: flanger, reverb, multimode filter, vintage delay, phaser, simple monophonic VA synthesizer, and organ/pad synthesizer. LADSPA+LRDF, DSSI, and LV2 versions are available, as well as GTK+ based UIs and a standalone application using GTK+2 and JACK.
Gleam is a software sound synthesizer. It receives timestamped synthesis events such as note on or program change and generates a raw audio stream. Early versions will provide wavetable synthesis based on the SoundFont 2 standard, but support for other synthesis models may be added in the future. Gleam is intended as a library that provides sound synthesis capabilities to other projects, but a few simple executable examples are included.
The Psychosynth project aims to create an interactive, modular soft-synth inspired by the ideas of the Reactable. It provides a clean object oriented API to allow the creation of new innovative interfaces for the synthesizer and a 3D simulator of a Reactable-alike device with support for collaborative music creation over the network.
FMS is a tool to create all kinds of sounds from scratch. You can play any sound (sine, triangular, vowels, etc.) with any property settings (frequency, volume, balance, sweep, etc.) and modulations thereof. It also features tools to save sounds, play .MUS music, graphically display sounds, and make real noise.
Algoscore is a graphical environment for algorithmic composition, where music is constructed directly in an interactive graphical score. The result is output to MIDI and CSound. Graphical objects are placed in a timeline and connected together. Some objects are fully dependent on user data, while some are generative and reacts on input from other objects. It is highly customizable and extensible with the Nasal scripting language. It has a non-realtime perspective where the composer can relate freely to time and construct the composition outside of time. This makes AlgoScore more like a traditional sequencer in this regard, but a graphical algorithmic sequencer with powerful and flexible scripting capabilities.
