Argyll is an ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, and film recorders, and calibration and profiling of displays. Spectral sample data is supported, allowing a selection of illuminants observer types, and paper fluorescent whitener additive compensation. Profiles can also incorporate source specific gamut mappings for perceptual and saturation intents. Gamut mapping and profile linking uses the CIECAM02 appearance model, a unique gamut mapping algorithm, and a wide selection of rendering intents. It also includes code for a fast 8-bit raster color conversion engine as well as support for fast, fully accurate 16-bit conversion. Device color gamuts can also be viewed and compared using a VRML viewer.
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
Artekopia Netjuke is a cross-platform Web-based audio streaming jukebox powered by PHP 4 and an increasing choice of databases. MP3, Ogg Vorbis, ASF/WMA, and other music file formats are supported. Artekopia Netjuke aims to enable small organizations or communities run a private "mp3.com-like" Web site to access the music they legitimately own, distribute, or are granted access to. It supports most audio players, language packs, optional file downloads, media protection schemes, multi-level security, shared and private playlists, random playlists, images, etc. It also features an unusual, easy-to-use installer module to get you started in minutes.
OpenEXR is a high dynamic range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. It includes support for 16-bit floating-point pixels (compatible with NVIDIA's Cg shader language "half" datatype), several lossless compression algorithms, and extensible image metadata attributes.
The Snack sound extension adds commands for sound play/record and sound visualization, e.g. waveforms and spectrograms. It supports in- memory sound objects, file based audio, streaming audio, WAV, AU, AIFF, and MP3 file formats, synchronous and asynchronous playback. The visualization canvas item types update in real-time and can output postscript. New commands and file formats can be added using the Snack C-API.
Webplay creates, from a collection of MP3s and Ogg Vorbis files (indexed from a directory or MySQL/PostgreSQL database), a Web-based jukebox with support for multiple independent streams. If Lame/oggenc are available, it can change the bitrate or codec of a file in real time to a selectable value. Each user controls their stream via a Web interface and can skip back, forward, or to a specific track; increment or decrement the bitrate; and check the current playlist, song, or bitrate. Playlists can be looped, randomized, played locally on the webserver, edited, deleted, reused, or renamed.
