This week I finished preprocessing to the point where I could comfortably begin work on the note identification and note onset algorithms. I got a simple initial algorithm for the note onset detection finished so that I could work on note identification for the case of an individual note. I have been working on this and debugging as I have gone, but should be done with isolated notes early this week. This puts me on schedule. This next week I will be able to finish out solo note detection and start to explore polyphonic note onset detection, which will then lead into polyphonic pitch detection the week after.
