Bike Crash and Audio Software Experiments
Today I crashed my bicycle on market street and front when I was trying to look behind for cars then I biked into the muni track groove and went flying over my handlebars and face into the ground. I sprained my left pinky, scraped up my face and knocked the wind out of my lungs. I found myself laughing, and noticed it was rather difficult to LOL and breathe at the same time. It was probably karma for the horrible things I’ve done over the years.
Additionally, I was working on a generalized method for note detection on musical instruments (namely the trumpet and piano). I wanted to avoid modeling the instruments general envelope or wave form in any way; essentially avoid any kind of precomputations and training stages, and just rely on my very flimsy knowledge of psychoacoustics. The idea was to be able to play my trumpet into the computer and have it transcribed into sheet music. Needless to say, I inevitably failed, but I did come up with some novel audio filters during my fruitless research.
Here’s the source code and some audio output example.
