What did you personally accomplish this week on the project? Give files or
photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
Implemented memoization for the Yin autocorrelation method. This speeds up computation significantly and allows me to take continuous lag windows which fixed the accuracy problem.
This is the output of the autocorrelation currently on a c major scale (frequency on left axis, time on bottom). This is now fully accurate.
I also implemented midi score generation. This is quick, flexible and fast. Generated sample midi scores and tested with Vedant’s model. Seems to be working fine.
Performed initial accuracy testing on a few different downloaded clean tone guitar samples. Accuracy >95% correct identification. The main source of inaccuracy is due to the tuning of the window sizes.
Worked on onset/offset detection. Found a few methods, likely going to stick with the built in aubio onset detection. There is some inaccuracy, but it seems good enough for primer generation:
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?
Integrate and more fully test pitch detection/onset detection.
