Implemented Yin autocorrelation method from paper.

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.
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.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
On schedule
What deliverables do you hope to complete in the next week?
Continue tuning pitch detection. Include onset detection for note timing and create MIDI score from input.
