Performous: A Challenging and Fun Karaoke Software for Linux

Oct 13, 2009, 17:03 (0 Talkback[s])

"Performous (formerly known as UltraStar-NG) started as a clone of SingStar, a PlayStation music video game. However, recent versions of Performous has become a lot different than SingStar in terms of features like its scrolling notes and precise singing pitch display as a wave drawn on screen in addition to the lyrics. These will allow the players to sing without interruptions and to easily correct their singing pitch to hit the notes precisely.

"What I really like most about Performous is its scoring system that makes it even more fun. As explained on its project website, the game records your voice via the microphone and it will undergo real-time FFT analysis. --This analysis reveals which frequency bands contain audio (peaks). Further test is used to find out the exact audio frequencies inside each band, and to combine base frequencies and their harmonics into single tones. Finally, some temporal (over time) filtering is applied to the detected tones to smooth out the output."
