We are developers of the Audacity® sound editor which runs on Linux, Windows, and Mac. Audacity is widely used, with around 15 million downloads in the past year from Sourceforge (https://sourceforge.net/projects/audacity). Audacity won Best Project for Multimedia in the Sourceforge 2007 Community Choice Awards (https://sourceforge.net/community/index.php/landing-pages/cca07/). Audacity has been featured widely in the media, including CNN.com (http://www.cnn.com/video/#/video/tech/2008/01/12/data.doctor.records.cnn), and a reference in a New York Times article. Audacity is a flagship application of the wxWidgets (http://wxwidgets.org/) cross-platform toolkit and it is widely admired as one of the only multimedia applications that runs beautifully on all three major platforms. Care has been taken to make Audacity work with screen readers for visually impaired users. Audacity has been translated into almost 30 languages, and nearly half of Audacity users use it in a language other than English. Perhaps most importantly, Audacity has a large and vibrant developer community. There are no full-time developers, but about a dozen team members who have been with the project for several years act as the leaders of the community, setting the direction and coordinating releases, but many contributions come from the dozens of other developers who have contributed small features, bug fixes, or other patches, and hundreds of other developers who participate on the mailing lists and help test and track down bugs. In addition, dozens of volunteers help with documentation, technical support, language translation, community support, and more.
