My project involves 3 separate parts
My project involves 3 separate parts
1) '''Fix widget bugs''' - There are several widgets in Music Blocks. As reported on github
repository <nowiki>https://github.com/walterbender/musicblocks/labels/widget</nowiki> , there are around
20 bugs reported currently. I think there would be another 10 bugs related to widgets which
would be reported during summers. I am planning to remove 2-3 bugs per day. Most of thebugs involve pitch-time matrix, tempo, timbre, filters, rhythm ruler. Most of bugs are easy
and they would be fixed in around 10 days. Other bug reports involve adding some
functionality and are actually enhancements.
2) '''Pitch tracker -''' It involves making a widget which would record sound, process it to find
fundamental frequency for every small segment, and then choose blocks (whose frequency
is closest to fundamental frequency of each segment), and then use these blocks to code
the recorded sound in Music Blocks language.
I chose to use fundamental frequency because it can be calculated in real time and is easy to
calculate as well. For calculating fundamental frequency I will be using autocorrelation as
feature vector. Autocorrelation is correlation of a signal with its delayed copy.
