In this paper, we discuss a system for musicians to practice rhythm with a musical instrument. Our system offers real-time visual feedback to the user about the rhythm played along with guiding metronome sounds. The system uses spectral flux and dynamic thresholding to find onsets in the audio signal. Usually, a real-time onset detection method uses annotation data, which need to be set manually and...
Mitochondrial dysfunction increases oxidative stress and depletes ATP in a variety of disorders. Several antioxidant therapies and drugs affecting mitochondrial biogenesis are undergoing investigation, although not all of them have demonstrated favorable effects in the clinic. We recently reported a therapeutic mitochondrial drug mitochonic acid MA-5 (Tohoku J. Exp. Med., 2015). MA-5 increased ATP,...
We are developing a rhythm practice support system with onset detection. The system produces guiding metronome sounds and processes the performed sound to detect onsets in real time. Spectral flux and dynamic thresholding are used to find onsets in the audio signal. We made three types of prototype display for the system; a survey of user display preference was conducted. An evaluation of the accuracy...
