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
