Capstone: Vowel Resonators

This isn't officially a capstone (I'm only doing them officially with my AP class), but it's a great project that she did to demonstrate her Advanced-level understanding of timbre and FFT analysis.

Inspired by a website, Grace constructed some of these vowel resonators and compared the aural and FFT results to those in the article and to recorded vowel sounds.  After that, she revised her resonators a bit, using reeds made from straws instead of the duck calls, and decided that these sounds closer to the original vowels (the duck calls were too bright).
