crtmpserver it is a high performance streaming server able to stream (live or recorded) in the following technologies: to and from Flash (RTMP, RTMPE, RTMPS, RTMPT, RTMPTE), to and from embedded devices (such as iPhone and Android), from surveillance cameras, and with IP-TV using MPEG-TS and RTSP/RTCP/RTP protocols. Also, crtmpserver can be used as a high performance rendesvous server. For example, it enables you to do audio/video conferencing, online gaming, online collaboration, and simple or complex chat applications.
Lush is a Lisp dialect with extensions for object-oriented and array-oriented programming. It is intended as a programming environment for prototyping numerically intensive applications. Unlike alternatives like Python or SciLab, Lush is designed for easy integration of existing C/C++/Fortran codes.
Swami is an instrument patch file editor using SoundFont files that allows you to create and distribute instruments from audio samples used for composing music. It uses FluidSynth, a software synthesizer, which has real time effect control, support for modulators, and routable audio via JACK. This project supersedes the Smurf SoundFont Editor, and is an entire object-oriented rewrite of it. The supporting libraries are GUI-independant and can be used in your own programs for doing SoundFont manipulation.
PianoBooster is a program that teaches you how to play the piano as well as the basics of reading musical notation. PianoBooster can play any MIDI files, listens and reacts to what you are playing on a MIDI keyboard. It makes sight reading music fun. It can make use of the "light keyboard" or "guide lamp" feature found in some keyboards, such as Yamaha EZ-200, Casio LK 220, LK-300 TV, and LK-43. Keyboards with this feature can cause specific keys to glow. PianoBooster can use this feature to show beginners which keys to press at any given time, even if they can't read musical notation.
The Kowalski project aims to provide a data driven, lightweight cross platform audio solution. The target audience is developers of games and similar applications where real time audio plays an important role. The Kowalski engine, which is the runtime component, relies only on host-specific external libraries to pass the final output buffers to the audio hardware. All other processing is done in the engine code. Features include positional audio (distance attenuation, cone attenuation, Doppler shift, binaural panning), real time Ogg Vorbis decoding, a powerful mix bus system, and tools to build, validate, and view Kowalski data.
LAoE is a graphical audiosample-editor, based on multi-layers, floating-point samples, volume-masks, variable selection-intensity, and many plugins suitable to manipulate sound, such as filtering, retouching, resampling, graphical spectrogram editing by brushes and rectangles, sample-curve editing by freehand-pen and spline and other interpolation curves, effects like reverb, echo, compress, expand, pitch-shift, time-stretch, and much more.
