This autocorrelation method is extremely slow. I changed windowing parameters of the autocorrelation and changed the frequency range over which the autocorrelation operates. Now the speed is acceptable (%70 length of input), but the accuracy needs help. The autocorrelation is finding the second most powerful harmonic peaks rather than the main fundamental peak.<\/p>\n

\"\"<\/p>\n

This is the output of the autocorrelation currently on a c major scale (frequency on left axis, time on bottom). The autocorrelation finds relative pitches very well. It sees whole step, whole step, half step, whole, whole, whole, half exactly as a major scale should be. It just thinks the fundamental is different.<\/p>\n
