Welcome to the joe wiki!

Joe was inspired by Joseph Fourier, polymath who showed us the Fourier Transform, and integral (pun intended) part of this software.

Currently written in (sloppy) p5js. Next steps include rewriting in threejs, unity, and C.

Design Goals:

Inputs
- microphone stream
- audio file (.wav)
Logic
- Calculate distribution of note based on desired tuning
- Visualize the staff
- Calculate desired fft windows
- For each fft
  - Once every frame
    - Calculate frequency values
    - Calculate overtone series
    - Calculate note probability field
  - Combine note probabilites
- Analyze collection of note probabilites
Fit analysis into rules of sheet music
Outputs
- "Realtime" visualization
- MIDI file
- PDF
- Mathematical analysis
