Server based pitch detection for web applications

Pitch detection algorithms ffnd use in many different applications ranging from automatic music transcription, music classiffcation and analysis to sound separation. Most recently, music games and karaoke applications have also incorporated pitch detection algorithms in their gameplay. Music and audio games pose different technical requirements in terms of the implementation and effciency of such algorithms. In this paper, we describe the development of a server based pitch detection algorithm intended to work in web applications. Real time performance, algorithm robustness and effciency were critical aspects of this work.
