Google Glass Tuner
Listens and shows what note you're playing. Can also tell you how sharp/flat you are (using YIN (not FFT) to determine frequency), but initial testing showed inaccurate sharp/flat readings.
Significant audio processing inspiration from: https://github.com/lucns/Android-Audio-Sample/ and https://github.com/chRyNaN/Android-Guitar-Tuner
TODO:
- Change to Immersion
- Find better/refine pitch detection
- Have needle/some UI to show how sharp/flat
- Real-world testing
