Shreya’s Update for 2/19

At the beginning of this week, I was beginning to experiment with the exporting of time stamps for an instrumental version. In order to determine the desired amplitudes for the beats, I visually determined (from the time-domain representation attached below), the correct peaks of the beats and then searched through the wav file for the timings related to the desired peaks at the time difference per beat determined by the BPM.

Because I hardcoded the desired amplitudes for beats (I used absolute peaks) last week, I was trying to determine an algorithm for getting the amplitude of beats in a particular song. That amplitude would be used to search for the time stamps in a different file. However, this has been slower going. Because I can’t rely on the beats being the highest amplitude and instead, it needs to be primarily based on the BPM. For this week, I have been getting more false positives than actual positives.
My deliverable for next week hopefully will be an accurate amplitude determination for beats (automatic, not hardcoded) integrated into a different file that exports time stamps. So far, I am on schedule for the project as a whole. I have several weeks to finish up an accurate beat tracker.
