Performous – party gaming

Performous is an open-source karaoke, band and dancing game where one or more players perform a song and the game scores their performances.

Performous is more than a karaoke game. Instead of just displaying the lyrics, notes are also displayed and the performance is scored based on how well you actually hit the notes.

The game is released under an open source license.

Features include:

  • Top-notch visuals:
    • Fully OpenGL-based rendering.
    • Music videos as backgrounds.
  • Very accurate singing pitch detection:
    • Noisy environments are not an issue.
    • Multiple simultaneous tones can be detected and separated properly.
  • Intelligent gameplay with guitar and bass:
    • The engine determines what was intended rather than simply picking the nearest chord.
    • Hammer-ons and pull-offs are undoed when the player accidentally does them and then picks the note in the regular way.
  • Drums.
  • Dance pads.
  • Scoring system.
  • Supports songs in UltraStar, Frets on Fire and StepMania formats.
  • Audodetection of microphones and instruments from SingStar, Guitar Hero and Rock Band.
  • Solid C++ engine:
    • Performs well on slower machines too.
    • Rapid but still safe development thanks to advanced C++ features.
    • Plenty of threaded stuff like background loading of songs and videos.
