Singing Game
This part of the game is essentially karaoke, but with scoring and realtime feedback. The gameplay is similar to SingStar: the game analyzes the pitch of each singer and scores the performance based on how precisely the song was performed. As a reference, the lyrics, the notes and the singer's pitch are displayed on screen as the song plays.
Performous does not attempt to clone SingStar but rather has unique features such as scrolling notes and precise singing pitch display as a wave drawn on screen. These allow the player to sing without interruptions and to easily correct his or her singing pitch to hit the notes precisely.
Performous does pitch detection with fast fourier transform (FFT) combined with a sophisticated post-processing algorithm. This system is able to operate well in extremely noisy environments, even when using very cheap microphones.
On Linux the game autodetects any connected SingStar microphones and uses them automatically. On other platforms and with other types of microphones (e.g. webcams or analog microphones connected to sound cards) a best-effort detection is done.
Songs need to be supplied in UltraStar or Frets on Fire format. Performous comes with a tool named 'ss_extract', for converting SingStar DVDs into UltraStar format.

Famous quotes containing the words singing and/or game:
“Instead of singing like the birds, I silently smiled at my incessant good fortune.”
—Henry David Thoreau (1817–1862)
“The chess-board is the world; the pieces are the phenomena of the universe; the rules of the game are what we call the laws of Nature. The player on the other side is hidden from us. We know that his play is always fair, just, and patient. But also we know, to our cost, that he never overlooks a mistake, or makes the smallest allowance for ignorance.”
—Thomas Henry Huxley (1825–1895)
