Amber, McCoy Chapter 5

1. What minimum frequency range is required to view the impact of both vowel and singer's formant in a spectrogram?   0-5, 500 Hz
2. What are the differences in narrow band and wide band spectrograms? Narrow band show all harmonics clearly while wide band shows frequency range of the formant zones.
3. What types of analysis can be used to help a singer develop a chiaroscuro timbre? Anything that shows the relative intensity of high and low frequency energy in the sound, but especially spectrograms, power spectra, and LPC.
4. What type of analysis is best suited to help a singer develop an even vibrato? The best analysis would be with a Narrowband Spectrogram.
5. Why does real time analysis feedback often work better for the male voices than the female voices?Males sing at lower fundamental frequencies where more harmonics are visible in the display (analysis display, that is...). There are also more harmonics there that can interact with the formants.
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? Accuracy goes way down, or is totally gone when F0 exceeds the expected frequency range of F1.
8. What is meant by the term, closed quotient? CQ or Closed Quotient, is the ratio of time the glottis is closed versus open during a cycled vibration, expressed as a percent.
9. Why is EGG analysis considered to be noninvasive? Because the electrodes used are placed externally on the neck, rather than shoving something inside an orifice.
10. What is a spirometry? A method or procedure used to measure lung/breath capacity.
