The Constant Q Transforms uses bins that are spaced on a log scale like musical notes. So the bins corresponds better to how humans perceive pitch. You wont waste hundreds of bins to the high frequencies. Calculating CQT can be roughly as fast as FFT. http://academics.wellesley.edu/Physics/brown/pubs/effalgV92P2698-P2701.pdf http://academics.wellesley.edu/Physics/brown/pubs/effalgV92P... And here are some real musical samples you can use instead of the artificial midi notes: http://virtualplaying.com/virtual-playing-orchestra/ http://virtualplaying.com/virtual-playing-orchestra/
