Hi
I have a project proposal that wants to track pitches from a guitar [non-midi] and then translate them into tablature that is readable by players. I was looking at fiddle and wondering perhaps if processingmight be of a help but I am posting her to hopefully get some pd feedback and perhaps a few ideas for implementing this project. Has anyone tried this kind of pitch tracking in pure data?
Hi Patrick,
I believe that there are quite a few people using pitch tracking for various things, and I believe that the current best practice for general pitch tracking is to use sigmund~, as Frank pointed out.
Pitch tracking, especially multiphonic pitch tracking is still an active research area and not an easy problem to solve, but if you're restricting yourself to a single instrument you can boost your accuracy by taking into account the harmonic profile of the instrument.
Check out the slides at http://www.ee.columbia.edu/~dpwe/e4896/lectures/E4896-L08.pdf for some good pitch-tracking info.
