To Do List // Notes

  • Find a good picture and some more information on formants. At least picture
  • More understanding of Fourier math - OK
    • Is there anything that explains the Fourier series in a similar way to "Who Is Joseph Fourier?" -- Yes. The wiki page. Duh.
  • How to use FFTW - snd2fftw? Windows utility, no makefile, easily cross-platform compatible?
  • section about pedagogical aspects of the project - Added
  • Analyzing the voice section: How to get from sound file to DFT
    • How do I get from audio file to an array? of values I can give to FFTW?
  • Differences between male and female voice - Done
  • Look into Octave (open source analog of MatLab)
  • Related technologies//applications
    • Kurzweil's device
    • Docomo translator
