In-game Music analysis must be implemented to execute ultra-fast while maintaining high accuracy. For Beat tracker, I considered that the rhythm is as a very low frequency component and set up very large window buffer (VLW). The application used this method is available to realize less than 1 second / song analysis time, 0.01bpm accuracy, 90+% correct rate and only 8 samples (0.181ms) average error of downbeat position. For Chord tracker, I optimized CQT performance with exact chord and modal music theory. So it is available to analyze key signature and modal with 90+% correct rate. Also it is available to output chord names including triad, 4th, 7th and 9th tension chords with 80+% correct rate. |
