This week I’m working on the rhythm processor. I wrote the code that detects the peak of an input audio signal in an interval of ⅛ of a beat. The program returns 1 if there is a peak detected in that interval, indicating that there is a note detected in that interval, and returns 0 if no peak is detected, indicating a rest note. I have also debugged the pitch processing by switching between different pitch detection algorithms and sliding window sizes. Now the pitch processor should be working accurately (which I will do further testing next week).
I am on track of schedule. Next week, I’ll start to implement the integration part that integrates the pitch and rhythm, which should be a dictionary or notes array that contain both the note and its lasting time. I will also work on the pre-processing to get rid of inaccuracies in pitch detection for the first few seconds of an input audio.
