BaNa Pitch Visualizer

Want to visualize the highness or lowness of your tone? BaNa is a pitch tracker for monophonic speech and music, which works well in noisy environments. The pitch contour can be detected and visualized for a loaded audio file or a piece of your own recording.

The BaNa pitch detection algorithm was described in the following paper: Na Yang, He Ba, Ilker Demirkol, and Wendi Heinzelman, "BaNa: A Noise Resilient Fundamental Frequency Detection Algorithm for Speech and Music", in IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2014. Please contact Professor Wendi Heinzelman at the University of Rochester at wendi.heinzelman@rochester.edu with any questions.

Thomas Horta, a visiting student, and Yun Zhou, a former M.S. student at the University of Rochester implemented the BaNa app as part of the Project Bridge at the University of Rochester within the Wireless Communications and Networking Group (WCNG): http://www.ece.rochester.edu/projects/wcng/project_bridge.html. Project Bridge is funded by the National Institute of Health NICHD (Grant R01 HD060789).
