Sinatra

Sinatra is a karaoke game, designed to be free and lean. The latest version released as a downloadable archive is 1.0, released on February 16, 2008, and considered an old version now, the only way to install a current version now being checking the code out of its SVN repository. It was written by Fredrik Portstrom in the C programming language. It uses the SDL library. The game is licensed under the terms of the GPLv3.

The game supports input from multiple microphones.
