Kangas Sound Editor QI lets you synthesize sound effects and music effectively from scratch. The QI variant of the Kangas Sound Editor has its own internal database engine (HSQLDB), unlike the regular Kangas Sound Editor, which needs MySQL Server to be separately downloaded and installed. Musical pitches are constructed using a system of frequency ratios, rather than the conventional equal-temperament notation. MIDI pitch numbers can be used to specify a base note from which other notes are relative. The user interface uses a system of cells or boxes, which are placed using drag and drop, and that have associated properties which describe various characteristics of the instrument, sound, or chord group. There is a kangaroo theme to this software.
The Arakhnê.org Network Editor (NetEditor) is a Java component that permits you to edit and show connected graphs. The graph defines the constructs of a visual language, and NetEditor is able to render associated figures. NetEditor is based on a metamodel composed of the node, edge, and anchor (or ports) constructs. It has a strong separation of the visual-language constructs and the drawings. It provides tools to code graph-drawing layout algorithms. Two algorithms are provided: Ganswer-Sugiyama and Coulomb-Hooke force-based algorithms. Standard UI features are provided: graphical editing of the graph structure, depth levels for nodes and edges, undo, and redo, clipboard, and drag and drop management. The NetEditor API is able to export the graphs to GIF, JPEG, PNG, BMP, SVG, PDF, EPS, PDF, Graphviz DOT, GXL and GraphML. The document file formats used by NetEditor are GXL, GraphML, or NGR files (zipped GXL/GraphML).
Given a chord progression and a music style, JChordBox generates a song. It is a library tool that can generate backing tracks from a chord progression and a music style. It contains several command line processes detailed in the user guide. It also contains a MIDI song player that can loop, play, pause, stop, rewind, forward, mute, or solo tracks, display transport information, and much more. It runs in a terminal.
nf1db is an in memory database engine with SQL and JDBC interfaces. It supports transactions, commands from the SQL-2003 standard, all major data types, a number of functions, default and null values, auto-increments, constraints, primary and foreign keys, set operations, implicit and explicit joins, nested SELECT statements, quantity limits in SELECT statements, and much more.
Bluehorn Reader crawls RSS feeds and makes their content available to clients (only a browser client exists currently). It supports multiple users, whose sessions' look and feel can be customized based on each place they log in from. A potentially useful feature is that, while it should be able to support a large number of users from a single host, if that is not enough, more hosts can be added to share the load, with only minor configuration tweaks. The Web server part is mainly in JSP, so it should be easy to play with it and adapt it to support other use cases.
AstroStack is an easy-to-use astronomical imaging and processing tool geared towards the use of inexpensive webcam CCDs. It provides a very tunable environment to produce the best quality images. It supports the following features: tunable webcam sampling; image stacking (averaging, additive etc.); pre and post-capture gamma (brightness) and contrast correction; dark-shot CCD calibration (subtractive); and an internal 16-bit grey-scale format for optimal resolution.
