The InfoWorld Bossies are chosen annually by Test Center editors, analysts, and reviewers. The winners represent the best free and open source software we've used. Our choices for productivity applications were led by contributing editor Mike Heck, with an assist from the "Office killer," senior analyst Curtis Franklin Jr.

Audacity can handle up to 16 channels at once (with the right hardware) and dubs over specific tracks to create multi-track recordings. Basic editing is straightforward, and the usability extends to advanced features, which range from a drawing tool to alter individual sample points to the envelope tool for smoothly fading volume up or down. If you want to do more, Audacity’s effects let you change pitch, remove background noises, and alter frequencies with an equalizer – which is aided by a spectrogram mode for visualizing frequencies.
Blender is a consummate example of the influence and opportunity for open source. Backed by a truly global developer and user community, the 3D modeling and rendering suite runs on Windows, Linux, OS X, Irix, and FreeBSD – a breadth of platform support unmatched by commercial offerings. It lacks some of the features and polish of commercial counterparts, but its pluggable raytracing engine offers zippy rendering. Microsoft’s Caligari trueSpace – just made freely available (though not open sourced) – is the only worthy rival.
Easy and extensible, Firefox has set new standards for the Web browser with the recent 3.0 release. The new look is more streamlined, less clunky, and the active elements such as the newly retooled location bar offer a new way to work with the Web. Security is not only far better than any other browser, but also less intrusive than you might expect. And the ease-of-use additions, such as the ability to save a session on exit and the wonderfully implemented full-page zoom, are instant winners.
Just as Adobe Photoshop owns the commercial space for graphics creation, GIMP (GNU Image Manipulation Program) is the top choice for photo retouching and image composition on X Windows systems. GIMP gives you a wealth of functions that nearly match high-cost applications. Complex tasks such as correcting perspective and color are effortless. Other advanced functions include clone (to get rid of unneeded details) and touchup using the healing feature. The software supports both common file formats and unusual ones (including multi-resolution Windows icons).
