1. What minimum frequency range is required to view the impact of both vowel and singer's formants in a spectogram? 0-5000 Hz
2. What are the difference between narrowband and wideband spectograms? Narrowband spectograms divide the frequency spectrum into small segments and wideband spectograms divide the frequency into broad swaths: individual harmonics can't be seen but formants are easier to see.
3. What types of analysis can be used to help a singer develop a chiaroscuro timbre? Any type of measurement that can assess both high and low frequencies can help a singer develop chiaroscuro.
4. What type of analysis is best suited to help a singer develop an even vibrato? The narrowband spectrogram because it is easier to see the vibrato.
5. Why does realtime analysis feedback often work better for male voices than female voices? Men sing in a range that permits a large number of harmonics to be visible on the spectrograph.
6. What is the minimum sample rate required to analyze frequencies in the 0-11kHZ range? 22kHZ

7. Why is formant analysis with LPC often inaccurate? As soon as F0 becomes to close to F1 the computer can't decipher it.
8. What is meant by the term closed quotient? Closed quotient is the percent of time that the glottis is closed during each cycle.
9. Why is EGG analysis considered to be noninvasive? EGG analysis is considered to be noninvasive because it is all done externally, and is measured by vocal fold vibration.
10. What is spirometry? Measures breath capacity
