my reward
BTW: I figured out a great reward for me. If I get my two cornerhost mini-projects done during the day, I get to spend the evening working on fun programming stuff. :)pyjama update
It turns out that if you want to sing into a microphone and then determine the pitch, the easiest thing to do is let the Snack toolkit do the
work for you. It can record a sound into memory and then show you
the pitches, even at the 10-millisecond level.
So I wrote a little tool that records me singing, saves it as a
wave file, and also saves the pitches as a python array.
Then, I wrote a python script to match the pitches to the
closest "pure" musical note.
Then I wrote the notes out as a simple Haskore program and played it.
It sounds horrible! :)
The good news is that the system works end to end. I can record sound and generate a midi file. All I'm missing is some intelligence to turn the raw pitch data into single notes of particular durations.
That's going to be the tough part.
